all fit great but get the muffler

Dominick O’Connor
Sounds awesome

It has a very nice deep tone while on those low RPM’s and a nice controlled loud tone in the high RPMS’s. It was pretty easy to install but the only problem was that it was a little bit short on the bumper so some of the exhaust fumes gets on the muffler. It also made my gas millage better. Btw if you’re gonna be installing this on a g35 coupe like me you will need an 8 inch by 3 inch wide extension pipe.

Bolted in no issue only concern was that I had to take the tail end of my old downpipe to make a spacer to allow me to tighten down the clamp tight enough on to the port on the downpipe it was too small needs to be flared out more otherwise works perfectly. You do not check engine light. You will need a spacer and tune
