OK when i first got my car i had a flowmaster on it..not the catback but just the muffler cuz i got it free....i was just wondering i have a 3 inch cat back and i was wondering if i put the flowmaster on this would it sound alot diff than it did with my stock exhaust pipe?

 

Im also curious because i am about to do the same thing. Except I will be running a 3 inch I pipe with a gutted cat. How much diff will this sound compared to just the Flowmaster muffler with stock everything?



Compared to this

 

Its gonna make the tone a little bit different, but with the 3 inch pipe, you can support more mods that will change the exhaust note. I have hedman headers and 3 inch pipe, into a 40 series delta force single in/out. It sounds pretty good for a stock L03

 

yeah, itll have a little different tone, and probably be a little louder. it will also perform better as long as you have a 3" y-pipe as well.
