I just ordered my fabspeed secondary cat , Cant wait to install them and I have read about primary cats , and found supersprint primary cat http://www.supersprint.com/en/IT/pro...s_pre_kat.aspx
did anyone here install them ?
thanks

 

I used leistung motorsports primary cat delete pipes. They are less expensive than fabspeed. My mechanic did the install. He did mention it was pretty "tight" due to access of the bolts coming off the turbo to the primary cats.
