at low rpm's, does your fabspeed make a "pppfffffttttt" sound? i noticed even when stock, 997's make that noise. but with the muffler swap, its way more pronounced. i really noticed it the other day in a parking garage. i wonder if its actually leaking air somewhere. or maybe its just that its more noticeable since the fabspeed is louder overall. i liken the noise to the classic vw bettle sound.

Nope, just a nice little burble sound. Actually the Fabspeed sound the most like a Cup race car to me than any of the others.

Nope, my fabspeed sounds as above....

Yeah my Fabspeed sounds sweeeet! Loud and beastly, although sometimes I do sort of hear a 'backfire' type sound or a 'pop'.

Yes, I had the pfharting sound... it gets better with miles. I had it the most with the full exhaust set up...headers, high flow cats, and mufflers... now it's less for some reason with the X-51 manifolds, stock cats, and Fabspeed mufflers. The old set up was too loud, it made my ears ring every time I went past four grand, at full throttle.

My Fabspeeds do the farting thing at start up and low speeds - just like the stock mufflers used to except a bit louder.

Add BEANO to the fuel system.... That should stop it!

Geez what smells in this thread...

Dave, me thinks you could use some too listening to that .wav file!!
