Default Does Flowmaster=Bad???

I had B&B tri-flow on before, i got a flowmaster muffler because it was cheap, and it sounds better and louder than the B&B i had before. When i look around the forums everybody bashes flowmaster. Is it really that bad compared to other regular Mufflers (ex: B&B).

Some flowmasters are designed for sound nad not flow. Therefore, they have multiple baffles in the muffler that eliminates the raspy and upper end exhaust notes leaving a deep rumble. Good sound yes, very much so. But bad flow which means less horsepower.

I'd like to see more proof as well. I was just at the dyno, and gained only 7 hp opening a single 3" cutout right before the rear axle vs going through my flowmaster. Mods in sig.

i kinda doubt that, mine only dyno's 326 rwhp and i have all done as him, with more, minus the ls6 intake, and slp, though i have a borla catback and with that flowmaster+y i would imagine the gain is about even

just my speculation. based on listed mods.

not to say its impossable, just a little hard to swallow.

on top of those mods ive also sealed the air box to hood. i dont think those gains would be listed though, i wasnt dynoing in a wind tunnel :p

Did you see the dyno, or is that just what he told you? 352rwhp would even be strong for a car with longtubes.

Regardless of what most people tell you man, it still flows better than stock. Just think of it like that, sure there are better mufflers out there, but it's still a worthwhile upgrade from stock.

But would you trade a B&B for a flowmaster? A B&B costs twice as much doesnt it?

A4's do take quite a bit more power then M6's, now sure about 30 hp, but probably more like 10-15 more

I feel a bit cheated. I am having my first Dyno Run on Saturday at Colvins in Austin Texas. I'm gonna be disappointed for sure. Stock the WS6 supposedly has 340 ft-lbs, and 320hp, with all the mods in the sig. Does this mean in reality i'll have mayne what my owner's manual say's I should have stock?
I don't have my sights set too high, but I am hoping for something around 350ish. I mean what the hell is the purpose for spending hours and hours and dolla after dolla on mods just to get back to what the car is rated from the factory with?......Getting pretty sick of it.
