Catalytic Convertor 95 altima

hi i was just wondering if the cat in a 95 nissan altima is a bolt on......because i wanted to get a test pipe and be able to change it out when emissions comes around. so if anyone knows please help me and will my car run better or worse with a test pipe and catback?

The test pipe should bolt right in. I don't think you need any new gaskets. It will sound awsome. Get rid of the OEM putt putt noise. The cheaper systems are too loud when you are crusin on the freeway. You may notice power feeling a little flat off the line with a noticable improvement increasing above about 1800 RPM.

thanks man i got a header down pipe test pipe and cat back!!!
