2020 RST 6.2 Headers

[Butch Peyton]

I currently have Borla S-Type cat-back on my truck since new. Sounds good now, but having my Kooks headers with catted Y pipe installed. I'm certain it's going to be to loud for my liking. Anyone run in to this and if so what muffler did you go with that tones it down. 

It's getting tuned, dfm delete, cam and heads worked over.

It will be loud as hell, and I have no answer to that but who is/ how are you going to get it tuned?

GPI is doing all the work. Dyno tuning ecm and tcm, head porting, springs lifters and pushrods, DFM delete, intake porting, headers with catted Y pipe and trying to pony up for the whipple but funds may not allow. I still have a few weeks before dropping off so maybe I can pony up those funds.

Glass pack resonators. I’ve done it more than a few times.
