I'd say use ZZP's resonator andgo with no mufflers!

Thanks for the link. I think Magnaflows, and a removed resonator, will be the way to go if I ever decide to change to a cat-back system. But for now, I'm keeping the stock mufflers, and removing the resonator.

Honestly, I would not get the magnaflow system. I would keep stock, get a straight downpipe and put some flowmaster 44's on there.

To clear up some misconceptions, I didn't get a Magnaflow catback. I purchased two Magnaflow knockoffs, and a 3 1/2" custom piping from a local shop, with a resonator delete, for about 90$ total.

That's not stock. It's noticeably louder than our bone stock GXP.

So it would sort of sound like this (40's instead of 44's, with a removed resonator):

do you guys know how much it will cost me to buy back my monte from the insurance company if they claim its totalled?

Am I the only one who thinks the flowmasters sound like crap? Too deep and forced, plus they are restrictive or so I hear.

SSWS6

Interesting. May I ask why you say that since you own a MF cat-back? I'm just curious since I may be doing exhaust for this car shortly and was considering the MF cat-back.

SSWS6

Couldn't tell ya. That price will be determined by them. And thats assuming they will let you buy it back. Some insurances won't let you buy it back for whatever reason.

I think they're OK. And aren't they cheaper than Magnaflows? BTW, I found another video of a GXP with Flowmasters, and the resonator put back on:

Ya for the most part Flowmasters are cheaper.

I like the sound of flowmasters, on most cars, and I don't think they sound like crap, but I think they're definetly way overdone which is why I got rid of the Flowmaster cat-back on my T/A and got a Spintech.

I have stock exhaust with the resonator removed and it sounds great! There is absolutely no rasp either. I read these posts and wonder where the rasp that is spoken about is?... It is not too loud and just right for me. I even got a compliment from a cop that is sounded good. lol... I wonder if the mufflers are different on the GXP than the other V-8 W-Bodies? If you have a GXP then I say just remove the resonator and go from there. I know you'll be pleasantly surprised.

I agree. In case you might have missed it, here's a video of your exhaust setup:

Next week I'm gonna get the res taken off my LaX Super, but leaving the stock mufflers on. As to whether the GXP's mufflers are the same as the Impala SS, Monte SS, and LaX Super's, I suspect they are, since I think they're all made at GM's Oshawa 2 plant. It'd certainly be more cost effective to use the same parts.

ick....I certainly hope it sounds vastly different in person. Sounds like somebody stepped on a dying pigeon.
