geez, had i known trubendz sold 3 bolt flanges i could have save myself $130! then again, its illegal in CA for a shop to tamper with a stock cat, at all......but i do know backyard welders..
Matt, i still have my stock 2 bolt flange cat if youre interested. all youll need then is the donut gaskets for your msds. do you have the msds Y pipe? or just going to optimize your stocker?
