I have RV6 HFs, XLR8 Jpipe and exhaust non resonated and im getting alot of rasp in the 4-5rpm range I want to get rid of. Im thinking about getting a resonator but not sure which one to buy. Anyone have suggestions or have this problem? Thanks

Dynomax resonator for stage 3?

 

I have a Dynomax on mine. Originally removed the factory resonator after doing the XLR8 v2 J-pipe and removing the mid-muffler (have stock precats) and while it sounded great at idle and full throttle, part throttle was just too raspy, especially above 3000 rpm. Adding in a Dynomax resonator completely removed the rasp, actually sounds really good now.

 

I recommend looking into the Vibrant ultra quiet resonators. One or two of those welded into place will really help reduce drone when cruising.

Dynomax or Vibrant resonator FTW. I myself have ran both and I like Dynomax's 'crispy' tone. Vibrant is a once sh*t company that has climbed pretty far and has paid special attention to their quality and it's beginning to show...especially in their exhaust products.

Either way, both will resolve the problem. Go with a longer (greater than 15") resonator to get a respectable result.

Good luck.
