Love the sound and setup! Curious did you feel any gains from the JBAs shorty headers with stock y and stock muffler?
I put the Shortys and new y pipe on at the same time and I can tell you I got a big kick in the pants. the shortys give anywhere from 10-12 horse power and the y-pipes is bigger all around, 10 horse power from there. I rune an 89 octane tune.
The biggest restriction I think has to be stock y-pipe! I got instant power right from the get go. Knowing what I know now, I will not be buying a cat back muffler, ,
I don't think there are any power gaines, just a nice sound, I get that from my stock muffler!
