The exhaust is a JP piece and is made for the kit. Only prob the Y34 has a 6-cyl not 8. I have to cut some of the tunnel on the bumper out so I can bring the exhaust up a little. We wanted a full JP car, so we went with the exhaust. It's actually made by Apex'i. The wheels are Work Euroline SL. I'm sponsored by AME, but they won't be in for awhile....also Endless is making brakes for the car too.
