Flowmaster Exhuast

hazzywayy · 05-23-2006, 06:08 PM

Hey - new to the boards. Just starting payments on a '06 blue/blue M6 GTO and I'm investing in exhaust.

I'm wondering if anyone has any knowledge/experience with a flowmaster 40 series muffler on these cars. I was up at jegs yesterday and one of the guys there told me he didn't think the 40 series would work as a direct replacement becuase of the space/size restriction, and hanger location.

Is this the case? If so, that's really disappointing because all I really want for my LS2 is that flowmaster sound.

Just had Flowmaster Super 40's put on my car yesterday. The guy at the shop thought the same thing but I told him I had read of others doing it and he called Flowmaster and they sent the muffs he needed- inlet and outlet on same side and muffler turned on its side- they fit fine and sound great I think, but some people on this board seem to not like the sound.

I personally love the sound as well!

What he told you was BS!!. I have the Super 40's on mine......Flowmaster part number 952549. It is a 2.50" inlet/outlet same side setup. Took the muffler shop around 45 minutes to do.......very simple actually, as I watched them the whole time. Here is a clip from another GTO website you may be familiar with....its an 05 with just the Super 40's replacing the stock mufflers. I love the deepness of the idle. It rattles the rafters at the Spectrum every time I go there.....

. No interior resonance either. I highly recommend them if you like the Flowmaster sound as I always have. This is the 5th vehicle I have had them installed on and havent been disappointed yet.

I was 351/347 after CAI, x-pipe and flowmasters, 438/400 is with the addition of SLP LT's, underdrive pulley, heads and cam.

Husker GTO and I both gotthe 40's. I have an X pipe he doesn't. He had the SLP headers and I'm in the process of getting them. Both sounds great. The X pipe makes a slight difference in resonance. Mostly just a preference in sound.
