Looking to replace the header, (any brand) and was wondering what the best brand was for the 99 Cobra. I am also looking for some SLP Cat-Back exhaustfor the 99Cobra. Let me know if you guys know some good exhaust sites. Thanks. www.LMPerformance.com has some SLP, but let me know if you guys know if this company sucks or know of other better comanies. http://www.lmperformance.com/4114/50.html it is $450+Ship. Is this too much for SLP? Because i know as far as cat-backs to, thats kind of high.
