Im just inquiring as to how hard this would actually be. I really like the idea of greddys full Ti exhaust system. Lets say I were to buy the HKS carbon fiber and Ti exhaust x2 lets also say that I could custom order Ti tubing. How hard would it be to put an exhaust system together that mimmics other exhausts. I figure I could order the Ti tubing to pretty much any specs I ask for so i could have it molded similar to other catback systems.
