Call them. I don't want to speak for them, but they should be able to include it in your kit. They've been REALLY great accomodating people. Provided I can ever get the payment to them, I asked them to make a custom 3" exhaust with a universal Apexi World Sport II Turbo muffler (80mm/100mm). It's probably good thing I had issues with mailing them the payment because I just picked up an Si sedan. When I originally ordered it was for a coupe.
