Fully straight piped from the turbos to tips!
Apikol Intake and D.O. Dual Nozzle Stage 2 Meth Kit
Well the kit is a bolt-on from Audi Performance Tuning (APT), but rest was done by me, and yes, it was quite a bit of work, but I enjoyed it and the end result. I paid $1,500 for the kit, it came with everything.
