I finally decided to replace my exhaust system. I have a 1998 A4 TA with 53,000 miles on it. I was told my muffler a Thrush CVX is looking pretty ratty. I went to a shop yesterday and got a quote of about $450 in labor costs for replacement with a Borla 3way adjustable and Hooker LT super competition headers (ceramic coated). I wanted to remain 50 state emmisions compliant and the only LT headers approved for my car on Cali's emmisions laws were Hooker Super Competition LTs. I've been told that Hedman were also approved. I plan on getting my shift kit and line lock placed as well.
I've been told that fuel efficiency will decrease when I get my headers placed but other people I've talked to debated that.
Anyone have the 3way adjustable Borla Cat Back their cars? How do the settings sound to you? What setting do you have them for daily driving? Are they easy to adjust?
Anyone aware of any other LT headers 50 state emmisions approved for 98 T/As?
I appreciate your opnions. Thanx in advance.
