I am ready to get a new exhaust system. I am pretty set on the cattman cat back with the hot shot headers and budget b pipe. I was just wondering if the headers come with a Y pipe or if I need to buy that seperately. I don't want to buy the y pipe if it already comes with it. Also I was thinking about changing my intake to a short ram instead of a cold air. Would that be a wise decision? Also what kind of things will I be dealing with once my exhaust is installed, as far as SES lights or my car running different. Any input would be greatly appreciated.

 

y pipe is included in both cattman & hotshot headers. the intake is a judgement call, short ram is better for higher rpms and real cold air intakes are typically better low end. as far as the exhaust, you will have to relocate 2 secondary o2 sensors behind the main cat.
