I have an annoying drone at idle that I don't know how to tackle.
My truck was running the GM performance exhaust (made by borla) which eleminates the resonator in the middle of the truck.
While doing the engine swap, I had my two primary cats (which are HF) replaced with HF magnaflows and the latter two removed (all 4 cats were shot and throwing codes before the swap so they had to go)
After the swap was done and got the truck running, it was too loud. I got a performance muffler from borla ( XR-1 sportsman) that was added in place of where the stock resonator originally was and the truck sound perfect in all conditions except idle! When I step on it its loud, at part throttle its great. No drone at any rpm above ~ 1100 rpm
Thought any of you guys have an idea as to what I could do to remedy this. The idle sounds meh and the drone just garbles everything. I believe if its gone my truck will end up sounding just abit louder than my original setup (before the engine swap and with all CATs) during idle and part throttle.
Im open to any suggestions
