Well I am finally going to do it. I plan on ordering a flowmaster cat back system (Force II model) from Summit. I also figured I best replace my catalytic converter with a high flow one since I still have the original one on it. My question: I will probably do the work myself. 1. Are these direct fit cats easy to install ( i dont have alot of patience!) 2. What cat would you all recommend If I go to a direct fit? 3. What online company would you go with? 4. What size tubing (inlet and outlet) on the cat should I be looking for to match up to my new Force II cat back system from Summit and to my original exhaust? Thanks much for all your help!
