Anybody do a muffler delete? At first I had just the back resonator h-shaped one removed with the straight pipes but it sounded louder but not balanced and sounded like a mis-fire. So I added in the x-pipe and removed the 2 resonators [which people sometimes call the secondary cats] closer to the engine,it smoothed it out but also made it dead silent almost stock.


what are my choices now? aftermarket mufflers? s65 mufflers? or muffler delete?

thanks guys.
Hey streetlife, I made a recent video covering the muffler delete and video footage of the sound. I also took off the electronic valves and had no issues afterwards.

Agreed, there is most certainly a happy medium of louder than factory sound while not being obnoxious. I want zero drone and some noise say north of 4500 rpms. Clip above sounds great but with mufflers removed it may be too much, not sure.
