What mufflers you running and why?

[Lenie]

I'm ready for mufflers and exhaust and running low. I was interested in what mufflers you're all running and why. Also, what you've run in the past and why you've switched to something different. Interested in all your edgemicated info.:rolleyes:

[NOPANTS68]

I have Flowmasters on my Camaro. They sound wicked, are loud, and flow like garbage. Probably one of the worst flowing mufflers out there, but I have electric cutouts to aid in the flow dept.

Putting Borla XR-1s on our Chevelle. 3 inch with a stainless X pipe, and tailpipes to he bumper. Heard that combo at GG autocross on a DSE car and was hooked.

I have also had good luck with Magnaflows and Dynomax race magnums in the oval case series of each. They are quiet and flow air like mad.

My favorite combo so far has been on my Nova though. 3 inch pipe to the bumper, stainless x pipe, and race magnum bullets. It was loud but very streetable and I always got compliments on it.

[skatinjay27]

I always reccomend xr-1's as i love howthey sound unique but super bad azz.there also supossed to flow real good and they are fully SS to boot.

[Flash68]

Spintechs or nothing for me. I had Spintechs. And now I have nothing. :lol: :thumbsup:

[intocarss]

Car came with 40 series flowmasters and i hate them

[214Chevy]

Hey all, I want the Borla XR-1's for my Chevelle as well. But their website says they are for racing. With that being said, are they ok for the street?

[canrc]

I have Flowmaster 50 Series...Thought I would hate them....but I don't

[SLO_Z28]

Magnaflow 2.5in non mandrel bent, with a dual in dual out crossover style muffler. Very low interior noise and sounds great!

How loud do you want it? 1987 Winston Cup loud or a little attitude?Im sure I know the answer but humor me. Ha

[skatinjay27]

[HRBS]

The ultimate sound varies depending on what your backing it up against. However, we ONLY run XR1 on our builds. Our shop Camaro actually picked up .12 ET by adding them compared to none at all (open headers).
Most of our client builds are Big Blocks and they sound super aggressive. If you are annoyed by interior resonance then these are NOT for you. They are free flowing and loud. :thumbsup:

Here is a 510ci BBC with 3.5" XR1's we built a few years ago.

borla xr-1's 3.5" inlet and outlet
I like their slims, item #40536 w/oval 3.5" inlet and outlet but I was looking to do 3" from my 3" headers in oval tubing as I'm sitting pretty low. Would rather do borla's but it's looking like I may have to go Spintechs. Don't know if that's a good route or not as people seem to have a love hate relationship w/them. I noticed Scott changed from Spintechs to Borlas. I'm really trying to keep things tucked up for clearance. Open to all suggestions:question:

[John510]

Any of you guys have the stainless works ones? Curious how they sound

[69znc]

I run SSW turbo mufflers and I love them The right amount of resistance to lower the sound (lower is relative) when normal driving but the back sounds like musics when you get on it. Very happy. I run 3 inch all the way. Could not do 3.5 for clearance issues. Specifcially I run thier part part #: TM5C3O3OP . Have for several years. THey seat behind a BBC 632

[HRBS]

That sounds great, Steve.:thumbsup:

Thanks Todd. I heard your car a few years ago at the LG SEMA party. Back then you had your "old" BBC. What mufflers were you running back then ?
Yours sounded pretty bad ass too. I remember Mark L and I turning around when you pulled in and being instantly drawn to your car because of the sound.

[Vegas69]

Steve, they are magnaflow that dump before the axle.

[dubbleu]

I went with SSW mufflers, 3" pipe all the way as well as thier headers. I love the way my 540 BBC sounds. Not overly loud for the street or highway but when you get on it...... they sound sweat!!

[Barry]

I run a $32 muffler I picked up at Autozone. 3" in and 3" out...but that's after the electric cutout. On my LS6 Sonoma.

[rfrankb4]

I used Race-Pro mufflers from Pypes that came with a 409stainless 3" kit for my chevelle.

The reason I used them was the cost of the full system was very reasonable but I have been pleased. Interior noise is significantly less than the flowmasters it had before.

They might be too quite at times but I am sure my neighbors would disagree. The exhaust note is nice from behind the car. In front of the car the cammed LS valve slap overpowers the exhaust note. Inside the car it is reasonably dB levels. I can reasonably hold telephone conversation on the interstate due to the insulation but still get plenty of compliments.

My original plan was to run these until I decided to cough of up money for one of the Borla pieces but now I have decided to stick with this since it works out so well

[Rhino]

I can't answer the question for Todd, but my preference is turning them in. The reason being any exhaust/oil is blown toward the center of the car rather than on the tires.

[6D9]

I am running Hooker Aerochamber mufflers on the Camaro and love them. They have that crisp chambered muffler sound but almost a straight thru design. They are pretty mellow at cruise rpm's but rip when the skinny pedal is pushed...:thumbsup:

[Musclerodz]

We have run Magnaflow on most everything unless doing full 304 stainless exhaust. They sound great on just about anything plus no drone which I hate the most. I need to take a video of the 455 Pontiac with Magnaflow, sounds great. The 480hp crate LS3 with DSE headers was just plain nasty sounding when you stepped on it.

[jski67]

I'm running Xr-1s with a BBC...not too loud at idle and screams when you put your foot in it.

Here's an older video with the mufflers dumped in front of the axle. I've since added tailpipes and it's a good bit quieter and higher pitched.

By the way, I'm running a Ram Air restorations oval x pipe kit from the headers to the mufflers. It's a nice kit, but the transitions from oval to round to go into the mufflers are too long (which keeps you from tucking it up much). I kinda feel like they defeat the purpose of the oval. Just my .02.

I really like the XR1's. My only complaint is I kind find them with an offset or outlet which would have helped packaging.

Except, that I was never planning on changing to something else. I have Race Pro's flowing through a Pypes 2.5" stainless system with their X-pipe. At idle and cruise it is not a resonating nightmare, but when you get on it, it is a simply awesome sound!!! It is my opinion that an exhaust system can brag the best flow numbers, but sound like crap......and in the end, entirely personal choice. It's like buying stereo speakers or choosing a wine :unibrow:

[Tony_SS]

Magnaflow, 2.5 with an Xpipe. It's much better than the old chambered mufflers I was running.

I tried a Dynomax Ultra Flo on my truck, but there's too much drone. From now on its Magnaflow for me...

[67XR7]

went from magnaflows to 2 chamber flows because I wanted it a little louder at idle. flows just sounded like everyone elses car except for when I had them on full 3" exhaust on my last 5.0. now I'm running spintechs and am waaaay happy when Im driving they just have this sound I cant explain almost like a light rasp. needless to say EVERY PERSON who has heard those mufflers with the exception of one has liked them and have plans on running them on there car. my crappy cell phone video does zero justice but here:

I am running the Pypes Street Pro's with 2.5 inch S.S. and the X pipe..

With the 280H cam ,it is really Sweet Sounding at Idle, but at WOT, it is Intoxicating..Love it..

And there is a slight drone at some speed, but you can get to a speed on the highway when it is quiet..

[rocketman]

i have run flowmasters on everything i own and build for 20 yrs, IMO there the best flowing, best sounding muffler out there with lots of options for sound in there muffler line up

[LS1-IROC]

Just out of curiosity, why is this?

Because they flow reasonably well and are quiet. I run stock GM f-body system on my car and it's nice and quiet. I must be getting old...I enjoy my car so much more now that it's quiet. I like to drive hard on the street and I don't like to announce it to everybody:unibrow:

Ill be running dynomax bullets. and that's about it. Or a centered nascar style boom tube.

[skatinjay27]

No, I mean, like, why are the "turbo" style quieter?

they snake through the muffler casing passing the glass insulation the whole time as opposed to chambered styles where its got no insulation or ones like the xr1s where they do have a insulation but its straight through design.

researching mufflers Rob? By the way, I would want to know how loud, or how much resonance each of the mufflers had at 1800rpm where they all tend to drone a little bit (or a lot).

[John510]

Cool!

Now which one sounds the best? I don't mind giving up a few hp for a better sound.

Always researching each piece to try to avoid doing any one thing twice.

I agree on the drone. I'm thinking Borla stainless right now, maybe even a secondary resonator out back by the fuel cell, but we'll see.

Thanks for posting that. Anything to help get him off my back is much appreciated :rolleyes:

Rob, I would suggest you catch a ride in my car with Magnaflows, or Gregg's with Borlas, but those are both LS powered cars and an old school Ford would sound entirely different. Personally, I would try and find out what a set of Bassani mufflers would sound like. They have perforated chamber walls, but I think they also have a straight through passage. They might give you a nasty old school sound with a twist. They made the wimpy little 4.6 3V in my old car sound downright mean too!

I don't need a muffler to enhance the sound I need one to tone it down, remember this isn't an LS it doesn't need help sounding like a real motor. :rofl:

Mufflers are like wheels so many choices and in some ways it is very subjective. The db figures I posted only tell you level of sound. Also the hp and torque difference in the top tier is negligible.

holy crap does your axle move a lot side to side in that video...you might wnna look at that....it can't be helping you times...

I never uploaded it to youtube, but I did another video, its all optical illusion. The tires I have on there are over 2 inches wider (which is funny for being the same size) and they fit fine. The axle only walks about 1/4 of an inch.

[Ripped]

I'll add my 2 cents, and a lot of $$.

I went through, a long evolution, in the muffler department. I started with the magnaflow 2.5 kit for the 'stangs.

2eE7-JP7YPU


At 2000 rpm, I had an obnoxious drone. Considering that from 1700-2300 rpm was cruising speed, it was not long before I changed the mufflers.

I changed to 19" magnaflow mufflers. Quieter, but still droned and resonated at the same rpms.

After researching, I found that some people had added a tee'd resonator, to their tailpipes, to eliminate the drone.

wgf_KThcGDs


I did that. The "science" is that the tube, is to be 50% of the tail pipe length.
It worked. My car sounded like a quiet luxury car. Way too quiet.

I tried to figure out a way that I could have the car be noisier when I want and quieter when I want. I picked up a pair of summit cutouts and fabricated them into the tailpipe tee's. It worked perfectly. Quiet so I could listen to the radio, and noisier when I shut out the resonator tubes.

http://i550.photobucket.com/albums/ii440/67FEfastback/shocks%20and%20exhaust/100_3584.jpg

http://i550.photobucket.com/albums/ii440/67FEfastback/shocks%20and%20exhaust/100_3586.jpg

Then off came the 19" magnaflows, and on went the 14" magnaflows again, along with the installed resonator tubes.
This was better, flicking an electric switch, let me choose what sound level I wanted, quiet or noisy.
ijwxKDVnAec

Still droned though, when through the muffler.

The other 2 problems were; I was carrying around an extra 10-20 pounds of hardware under the car, and it was in the way of my rear brake cooling ducts.

Screw-it, I decided to bite the bullit and get a pair of patriot varaflow mufflers.
Pricey but I really love them, and wish I would have discovered them sooner. Essentially they are a stainless 2 1/2" glass pack, with an electric flapper valve in the middle. Closed, the sound goes through the mesh and fiberglass surround. Open, basically like a glass pack.
One advantage, over the electric resonator set up I had before, is that you can vary the flapper part-way, and have something between loud and quiet, if you want.
They only come in 2 1/2" though.

aEW4t_nOWmc

Oh yeah, they do not drone... even in the open, louder mode.

[Richio1]

I've got Flowmaster Super 40's on a 383 and love them. Some drone but not too bad. Plus FLowmaster is up here in Nor Cal so I want to support the local manufacturers as much as possible.

I will tell you what, I LOVED the sound of the DSE 69 Camaro when Staci was running it out at GG Pleasanton AC earlier this year. It was loud but sounded sexy in all the right ways.

They are running the Borlas but I am not sure which models.

I dont know, I'm just not on board with all the Magnaflow guys. I agree they sound really good when accelerating hard but other than that I dont care for the sound much.

[transam]

I run magnaflows on my mustang. Turbo car so its barely louder than stock,on my trans am i run magnaflows and its way too loud for me,i will most likely switch to a 50 or 70s series flowmaster
