I'm talking about the middle mufflers. YES I've searched and found a bunch of good info. I LOVE the flowmaster muscle car sound, but the flowmaster loudness doesnt belong on this car, but I love the aggressive tone. Original plan was some ultra flo's and an x pipe in place of the resonators. I heard a sound clip, still sounds a little louder than I'd like. NOW I'm thinking about keeping the stock resonators on there and just swapping out the rear mufflers with some loud flowmasters, with the resonators, that should really quiet it down and give me the sound I want. I'm just worried they're REALLY going to quiet it down.

I want it a little louder, and more aggressive, and with the intake making lots of noise under the hood that will suffice.
 
I personally went through about 7 attempts to get what I wanted.

The Flowmasters are way to loud even with resonators... I tried it! The resonating hum on the highway will drive you nuts! WOT though it sounds awesome!

Then I tried Magnaflows! First with x pipe and then put in resonators to keep seperate pipes. I did not see any gains either way so I just left the resonators on.

Magnaflows with the Magnaflow Resonators sounds awesome... this is what I am running now with custom 2.5 pipe right off the stock headers.

I have Pace Setter cats in place of the stock ones (not sure if they are any better than oem).
My advice is to get Kens Magnaflow kit! You will be happy..
 
yeah, umm.... Local exhaust shop is gonna be a couple hundred bucks cheaper, heh. I'm not a cheapass and would rather support someone on here, but a couple hundred dollar difference is pretty big

Could you elaborate?? I've been wanting a new exhaust.. Tell me the secrets of your ways....

One of the recommendations I got for my SHO was to go this route. Basically, you buy the cats and mufflers, then go to a local exhaust shop and have them fabricate the pipes to create a custom exhaust. This way you aren't stuck with what's in one of the packages; you can have Magnaflow cats and Edelbrock mufflers with stainless pipes, or Edelbrock cats and Flowmaster mufflers with aluminized pipes, or whatever combo you can imagine. (I don't know if either of those companies make cats, this is just an example.)

It's also usually the least expensive route to getting a better exhaust. If you have an '03 or newer, it's the only way to get anything other than the stock exhaust.
 
I have the res. and flowmasters and I think is sounds good at idea and part throttle but not at WOT. I might try loosing the res.

Remember...you get what you pay for. It is rare to find a local shop that can mandrell bend your tubing and utilize factory hangers and hardware. If it rattles or doesn't perform like the Magnaflow unit, it's a waste of money and you'll actually spend more money getting what you desire. But the Maggies and be done with it.
 
It's not gonna cost me 750 bucks to swap mufflers. The stock tailpipes are fine. Most exhaust upgrade gains on late models are in your head anyways. These days you swap exhaust for the sound, 10-15+ hp my ass, I'd like to see that on the dyno. And with such a heavy car do you realize how little 10 hp really is anyways ? You'd barely be able to feel it, if at all. I'd be surprised to see more than 4-5hp gain on the dyno from just exhaust. I'll save about 500 bucks and just have the local exhaust shop buy and weld me in some mufflers.

My car was the development platfrom for the Magnaflow V6. Trust me, it's 10-15 hp. They have a dyno in their shop. I saw them do it. The stock V6 piping is ~1 5/8" O.D. The Magnaflow is 2 1/4". There are also fewer bends and they are madrell bent. The exhaust is flows much more free. The reason Magnaflow backed out of the '03+ is because it was only 5hp. The stock exhaust is that good. I also asked their engineer about free-flow cats. He said the stock cats were already pretty free flowing and wouldn't be worth the cost.
