I have the exact same issue.. Sounds like a 78 Ford truck with a Glass pack on part throttle accelleration. Sounds like ****! Other than that its great. Getting ready to yank the Bullett and put in a 1 chamber Flow I think.

^I hope your right, I should be getting one sooner or later
Really dont think switching any parts/pipes would make a diff. My car sounds awesome when standing behind it/riding next to it. I can only hear it when im in the car driving

UNtil you delete it you will hear it. Simple. Its actually heard more under medium acceleration then WOT.

Like I stated before, it didn't do it before it was run out the back. When I had the exhaust run out the back, this was the first thing I noticed. Before, it sounded awesome in every way....just a little loud. I have been told by some 6-speed guys that they have a similar sound as well and they certainly don't have TM. So once again, TM is not the culprit.

I know not to use Sweet Thunders dumped if you don't want interior noise. They create LOTS of interior noise......but man they sound sweet. One of the best sounding cars I ever hope to hear. You're probably pretty close with the Spiral Flows. Also consider Magnaflow 4X9's and Borla XR1's.

Im bringing this thread back to life because I just got a bolt on dyno tune and most of the BLATTT sound was eliminated! Its still there but much more quiet in just about every gear, in every RPM. 5th gear in a low RPM is the most noticable. I highly recommend a bolt on tune if your not going to mod further, my car drives just like stock now.
