I would search high and low for another stock resonator myself. Or...fix yours, it can be patched/welded on.

I left my resonator on, and SURE glad I did. From idle, to WOT it sounds good. Inside...at any throttle, no drone. I'm pleased to say I have no rasp.

My set up:
TOGs.
3" DP
Gutted stock CAT
U-bend delete
stock resonator
3" custom made "Y" pipe from there on back. (Upgraded from my old 2.5" set up)
Flowmaster dual chamber mufflers
stainless tips, no internal baffling in them.

It does help that I have the Intense stage 3 heads and cam for the sound I have. But on a stock engine set up or any IMO...the key is not to touch the stock resonator if you can help it.
