It's is both raspier and deeper. Word is that the stock suit case looking mufflers with the resonator delete sound way better the the GM performance mufflers aka borla attacks
Is made it deeper and louder but not as loud as I would like. It's sounds really good if you delete the resonators on the stock set up more then the GM performance mufflers
I litterally did the same thing you didMuffler delete and I didn't notice anything Now going to hugs summit racing x pipe How is your car driving with the dod turning on
bigkarl24 Havent had any issues thus far, Xpipe is the better way to go long term. Resonator and muffler delete are the cheaper way to get some sound and flow out of the stock system. I have the GM performance mufflers which are aka the borla attacks, My buddy did tue muffler delete and hos sounds pretty good. I have only deleted the resonators on mine. Soon we will be installing electric exhaust cut outs in front of the cats, I make a video to show how it turns out Havent had any issues with Dod turning on.
