Power Gain from exhaust change. READ On my old ARE 375 W/ Fresh L92/L76 goodies I had a Groty LT /3" Y-PIPE into a 3" in/out Borla XR1 exhaust setup.
Yesterday I had the Y-PIPE cut and spliced into a flowmaster twin 3" in / 4" out collector and a 4" Bullet. I gained from 17 - 20 rwhp from 4000 to 7000 and the tq stayed exactly the same.
I just thought this may interest someone contemplating a large single over duals.

03BUSA,
I think you may have missed something in your reading comprehension. THE FLOWMASTER PART IS A MERGE COLLECTOR AND NOT A MUFFLER. The muffler is a dynomax bullet. 4" in , wide open, 4" out. The merge collector is (2) 3" inlet pipes merged to a 4" outlet, straight in and straight out. This setup will support 675 FWHP W/ 0 loss. I agree some mufflers seriously restrict flow but to say that flowmasters were not designed for F-body's is nutty. I assume your buddy bought the cheapest muffler he could find from flowmaster or the one that his buddy uses on his 225hp mustang that sounds great but is only desinged to flow the amount of air to support 225 hp and not the 325min the f-body was making. I'm not trying to sound like an azz but some of the stereo typical comments about a particular MFG just don't sit well with me when there are mathematical calculations to prove or disprove some claims.
FWIW I could care less about Flowmaster or any other MFG but I hate BS across the board claims about any MFG.

I apoligize, I did mis read your first post. The flowmaster car I was talking about, I do not know who's car it was just happen to be at the tuners dyno and saw for myself and was told that Flowmaster systems on F-bodies all do that. Either way that is irrelevant to this situation. Sorry for the confusion.
