That same old question...Flowmaster or Dynomax?
Ok I decided since my stock exhaust is messed up, I'm gonna replace it with a performance one.
So, which is best for the 2.8?
In terms of both sound and performance.
Price isn't that big a deal, cuz I already poured so much in the car, what's a little more.
Also, suggestions for a cat?

Dynomax has a smooth flowing stock sound, but flows better than the Flowmaster. Flowmaster is louder, so it's basically a choice of what you want. I like my Dynomax, and I don't think that too many people will disagree with me on this one.

Um Flowmaster is the leading exhaust company and Dynomax can be bought at a parts store. Think about it.
If price isn't an issue then get Borla.
Where is this Dynomax flows better than Flowmaster information? Which flowmaster system? They only have like 4 for our cars.

once again Kyle is spews his worthless crap. Dynomax flows better then flowmaster! I have seen several professional tests to demonstrate this fact. If Kyle has a dynometer I'd love to hear his comparisons.
BTW Dynomax sounds good on the 2.8.

Tell me where I can find one of these test. I have seen the Flowmaster results in Hot Rod and HPP and CHP. I have seen nothing on Dynomax.
Once again the board goes to trash talking. Its not only Monkie guys. Some people are just to touch about someone having a difference of opinion

Kyle, go ask that ? on the exhaust board....i'll bet you get the SAME answer.
Hey, Kyle. BTW, in case you DIDN'T know, Walker makes Dynomax....

Hey guys, check out www.goravin.com You cant beat those flow numbers. I guess its a reasonable price too. I'm not sure if they are just mufflers, but someone on another board was talking about a ravin cat back that kicks @ss.

In the Famous words of Dr. Culp
Liars can figure but figures don't lie"
What mufflers where they comparing? Mustan 2 1/2" or F-Body cross flow????? It doesn't say. Just because on company makes a muffler that out flows another in one application doesn't man they all do.
IMO nothing sounds better than a Flowmaster. I will sac 2hp for that sound, if that be the case. Is there a graph on supliers of F-Body mufflers? I bet none flow better than the Flowmaster 3"in 3" out. Maybe SLPs 3"in dual 2 1/2" out (both 2 1/2" on one side).
Its your choice man. My brother and I both have Flows and most people in my area do to. We love them.

Hey thanks Violate. I found another chart that shows Dynomax vs. Flowmaster.
Kyle, I never said either was better in ALL aspects. Dynomax flows a little better, and is better if you want more of a stock sound. Flowmaster produces megasound, but also has higher backpressure, and can actually reduce your power. Don't believe me? Just search the internet. I found a site, that showed a modded car running the 1/4 mile and stuff with different mufflers. The Dynomax was BARELY behind the Open exhaust, and the Flowmaster was Way behind. The Dynomax however was also the quietest out of the bunch. http://www.wauknet.com/douthitt/exhaust.htm
It's all a matter of personal preference. I'm not going to call Flowmaster a bad muffler or say your car sucks because you have one. My preference is Dynomax, because I don't care for a loud obnoxious sound, especially on a V6.

Kyle, I read the book "how to build horsepower" it had a chart showing dynomax being in the top 3 or 4 best flowing mufflers. Flow masters was about average.
Again if you have your own dynometer and have conduced tests, please post your results.

They are all good.... If I had all the money I could I would get Borla, but I really do like my Dynomax... I live in Florida so in 2 1/2 years it shows no age...

3.1 Firebird Maybe somneday I will have a dyno I can use because OU is building one for are Electric race car sao we can burg custom Proms for the controller. (ECM on our motors)
ANywyas I was asking if there were any on the F-bosy. All I see is mustangs which have a completely different type of muffler than ours. My brothether bought a set of Dynomax Ultraflows once, they were ****ing open exhaust. It was a straight shot through with fiberglass packed around it. Well he installed themn on a 3.1 (DOG SLOW) 95 Grand Prix. They we so loud it shook the change in the ashtray. He had them removed the next day. It all depneds on wht series of mufflers you are talking about. Its hard to compare apples to apples and oranges to oranges because the comapies won't show that. They will find a way to show theirs are a lot better.

Everything I've seen, independent (magazines) or non-independant (companies), has always showed the Dynomax outflowing the Flowmaster. Of course, some of those non-independant ones are like the Ravin' chart, putting theirs above all other mufflers- but if it was rigged, why have Dynomax above Flowmaster?
Besides, everyone puts Flowmaster on. That's enough of a reason to go with Dynomax. Like Monkie said, you wouldn't notice a seat-of-the-pants difference anyway.
