Exhaust Thoughts

[ccracin]

I'm getting ready to build the exhaust system for the truck. What do you guys think of the flex joints that are becoming more common? I was going to install them right after the header collector and then continue back with the exhaust system. Are there any issues with running them?

Also what kind of hangers are preferred? Anybody make those silicon grommets in black instead of blue?

On a side note how do you guys think this combo will sound? 415ci LS with long tube headers. 3" exhaust with cross over and Magnaflow mufflers.

Any comments are greatly appreciated!

Anybody???????

I'm using a Magnaflow 3" X kit on my 69 .

I would have liked to use an X, but it won't fit. I have to use a balance pipe instead. It shouldn't give up much.

I saved this article, its a good read when your building an exhaust system.

Thanks Speed, I have that article as well. That is the reason I was not overly worried about using a balance pipe instead of an X. That's good stuff there! Appreciate it, thanks again.

Chad --

I built an all stainless exhaust system for my buddies 55 Post - Art Morrison frame - LS2 motor... and I used the SS flex exhaust - one in each side. The reason I did that was because the exhaust runs thru the frame on the AME piece... and I didn't want to "risk" the chance of it becoming a rattler down the road. The flex pieces isolate the motor vibration and any movement etc.

They look good and were nice pieces to use. I TIG welded the entire system and made custom mounts for it.

You can see the flex pieces here - and the "tight" fit through the frame - the pic sucks (it's dark) but you'll get the idea.

Thanks Greg. I have a very similar application. Although I built the chassis, I have some clearances that are tight and thought these would be helpful. I just wasn't sure about the longevity of them. Speaking of your custom mounts, what did you use for isolators? I have been looking at the blue silicon grommets, but they don't match anything I'm doing. I don't want to sacrifice function, but they will stick out like a sore thumb. Thanks again for the info.

Later,

I used the blue ones you hate... LOL

The car I'm putting together for my buddy is a "driver"... to those aren't issues for him. They also have red versions.

I was in search of the black mounts as well.no luck just ended up machining cover to cover the blue up.Somtimes it's not how good you are it's how good you can cover up the uglyness.

Seriously - who or what is the "Welds" you are referring to?

[Garage Dog 65]

You're talking about the WELDERS SERIES.... okay -- got it -- yeah they have all manor of brackets and stuff. Good supplier!

[Garage Dog 65]

Yes, Paul Horton's welder series. They have tons o brackets and stuff.

Here's the isolators from their site:
