- got my ep3 3" exhaust kit in last night, perfect packaging and perfect exhaust. Had it all welded up today with a vibrant muffler on the end, all i can say is WOW...quality work, perfect fit and sounds amazing. He also made me a transition piece so it can bolt easily up easily to my race header. Highly recommend this exhaust kit and seller, very friendly and knows what he is doing. Thanks again!!!

- ASP, Stefan, and Charles know all aspects of tuning. Building headers/R & D, fabricating/installation of parts, K-Pro/ECU tuning, troubleshooting problems, and answering questions/giving suggestions. These are all things that they have done for me. We are very lucky to have them on board at K20a.org!! It's the only place I have taken my Kswap to and they have put me miles ahead in the game.

willing to answer questions and is very patient. I would recommend to ANYONE.
Best of luck to you in the future Stefan.
