Reducing Rasp?

I have LT headers, Prochamber o/r mid pipe, and roush abs. Now in my opinion, best sounding v6 at idle ive heard so far, especially with my ghost cam on, nothing but compliments. It screams at WOT, but those mid RPMs can be a bit.... raspy. Would resonators change that drastically? Any thoughts would be great.

As im starting to hear... lol.

Its so beast at idle and with that cam lope, but once I get on it I cant stand that rice sound. Of course it is a 6.... but still. I was thinking of changing the abs out to a borla stinger and resonator set up to test out.

Resonators work WONDERS! Trust me, my car had a terrible rasp before I put my resonators back on, and it is much much better now!

I had Borla LTs, a custom O/R h-pipe, and Pype Bombs. After adding 18" resonators, and switching to Borla S-types, the rasp is hardly noticeable. It only shows up around 3.5K RPM as the exhaust note transitions from deep and throaty to screaming racecar haha. Keep in mind that you'll never fully get rid of the rasp simply due to the nature of our engine, but you've already got a pretty solid game plan.

They subdued the rasp quite a bit. It didn't really deepen the tone, it just made the deeper sound more noticeable by removing rasp

It usually depends on what else your running in your exhaust system. H-pipe our x-pipe? Off-road or catted? Muffler or straight pipe?
