"What's the best sounding muffler for my car?" We get this question a lot and there is no right or wrong answer. Ideal sound is based on individual preference and will vary from person to person. This is why Flowmaster offers over a dozen different series of mufflers, as well as several Cat-back and Axle-back kits, for nearly every popular make and model of vehicle. We provide everything that you need to tune the sound and performance of your vehicle's exhaust system to your specific wants, needs and budget. In this video, 8 of Flowmaster's most popular mufflers are tested, from mild to aggressive, in order to help you figure out which muffler is right for you. Keep in mind, the sounds heard in this video reflect how the vehicle sounds from the exterior and are not representative of the interior noise that may or may not be generated inside of the cab under normal driving conditions.

Any reason Flowmaster doesn't make these mufflers in 304 stainless? Its tough to build a nice matching 304 stainless exhaust system with 409 mufflers.

We do have a few: Our Super HP-2 and DBX Series mufflers both come in 304 stainless as does our Slim Line Sidepipe.

Thank you for the response. I was actually more interested in the delta flow line. Many of my customers who want a Flowmaster want the sound that is created with the delta flow. Many of the available options out there in a oval case in 304 stainless are perforated tubes through a metal or fiberglass wool. The sound is much different.

We appreciate the feedback. This may be something that we will consider in the future. Thanks for your insight.

Agreed. I had to ditch my loud magnflows and wanted to go Flowmaster but the lack of 304 meant I had to go with stainless works mufflers instead.

Can someone explain the difference between 304 & 409 stainless? Just for those of us who don't know....

THANKS!

409 will corrode to an extent while 304 won't. A magnet will stick to 409 and not to 304 if you need help determining which stainless steel an exhaust is made of. Please understand this does not mean 409 is bad. It's still much better than aluminized steel. It's just that it is cheaper than 304 so the price should reflect that. My pypes system is 409.

Great description. 409 stainless steel has a slightly higher iron content than 304(shiny) stainless steel. This makes it easier to weld, more durable, stronger and longer lasting than a 304 stainless steel, but because of that, it will show light surface rust over time. This surface rust actually acts as a barrier to protect it from rusting completely through even under extreme conditions. Most major automakers recognize these benefits and currently use 409 stainless for their OEM factory exhaust systems. Because of its durability, we back our 409 stainless steel mufflers, systems, and kits with a Lifetime Limited Warranty, so you'll never have to buy another system again.
