Hey Tsx owners....So Ive finally decided to do somthing to my whip. Ive owned it now for 3 years and just have it tinted and have a sound system and just drive the shit out of it. It is a beautiful car and I love it. it has 107k miles I have blizzak tires also for the winter so my baby and i are having fun come winter time. On to the good stuff....I called my local exhaust guy and he is setting me up this weekend with a Injen Sp cai and an exhaust system. I need some advice on the exhaust system before I go in there. The Injen is already ordered, but the exhaust is not picked out yet because he says he wants to look at the car with me. But regardless I am putting a exhaust system come saturday. I just don't know what to do with the car. He sells magnaflows, flowmasters, and some other exhaust that sort of look like flowmasters. He said we can do cat back systems to. I need advice on what is best for performance and what i should do.
