As subject states I have an LS2 based 427. Currently I have TTS headers (not around anymore they are five years old) a catted Y pipe and GMMG exhaust. The headers and catted y pipe I’ve had on the car when I first got it. Did the motor build a couple years later and just reused but now that I’m getting into more performance things I want newer and better, taking the car in a different direction then I was at first years ago. I’m looking into buying a set of new headers and an ORY. Just want some opinions on what’s the best route or a couple ways to go. Looking at a race style header, no egr, and I already have O2 sensor extensions. Any comments wanted

 

We sell a great 1-7/8's system for your car I'm sure you'll get many opinions. The ORY with a 427 and a GMMG will sound insane.If you have questions or need help PM me and I'll do what I can

 

insane being good or bad?? love how the cars sounds now what will be the difference in sound with out cats?

 

Sound really is a "taste" thing I had headers and ORY with GMMG on my f-body with a G5X3 cam and it was really loud I liked it back then not so sure I would deal with it now. If you liked it before I doubt that you would hate it after it will be a tad louder with no cats especially at WOT
