I just did both a muffler and resonator delete today primarily to save weight for autocrossing / track. H-Pipe was left in place. Definitely loud, but I knew that going in. Less drone than I expected as well.

I had them put a flange on the tailpipe tips as well as on the original SRT-6 muffler in the event that I need to put it back on quickly due to a sound violation during autocross.
