I'm ready to purchase and install headers on my 07 tC. i am most likely going to go with the mmw set up because i want a 4-2-1 stainless setup and an s-pipe. What are you all doing about the cat??? does the tc have 2 cats? (i havent been under the car enough to check it out)
2 things... 1. is that ive heard that certain cars dont run right w/o a cat, is this true with the tc? and 2. this is my daily driver, i dont see how i'm going to pass inspection w/o a cat...
any advice? comments?
