Hey guys,

So, I'm got a 2.4 auto with more-or-less a stock exhaust again. I had a GMPP Performance catback first by it's self. It added solid performance but was loud. I added a ZZP header/dp combo to the mix, and it was insanely loud. Removed the header/dp and went back to just a GMPP. Then, I went with a custom exhaust set-up with GMPP tubing, stock SS resonator, and a Dynomax Super-Turbo muffler. It flows great, sounds mint, etc. Love the set-up. But i'm curious about adding another header/dp.. Will it make it insanely louder? I just remember that my header/dp and GMPP was crazy loud, but the GMPP was very loud alone.. This set-up is much quieter and flows actually better.. So, anyone have a header/dp on their stock exhaust? Because for all intents and purposes, my exhaust is mostly stock now.. How is the sound and flow with an aftermarket header/dp on a stock exhaust?

Thanks guys!
