yeah I want cats on the car to keep it from being raspy and ungodly loud. Just curious to see if anyone is running it. I am looking at the Kooks 1.75" headers and there h-pipe for the boss. But a huge huge part of me does not want to do a header install. I know what a PITA it is. Wish kook's would just make there H-pipe modular so it will work with stock headers then later add a piece and works with there headers. SLP does this with there stuff but they dont make a h-pipe for the boss that would retain the side exhaust.
I was thinking of getting that for when I finally get a Boss but you would need a tune or else you would throw a code which is what made me decide to keep the stock H-Pipe until I was ready for a tune. :-\
That was a question I posed on another forum and a member had said that at first their CEL didn't come on so they said a tune wasn't needed but eventually a light did come on which is why they changed their position on the issue of needing a tune and I remember Kendall from Cool-Tech saying that some one kept having to fiddle around with cats and they thought they found one that wouldn't throw a code so they released it and eventually their car ran a code so they changed their stance on the product and the MRT is the only one that I know about that still utilizes cats. I really like how it sounded and it opens up the exhaust from the restrictive factory H-Pipe which I liked as well. When I get out of work I will see if I can find the post that Kendall made.
