So i just got this exhaust system. i read the directions and i really think they gave me the directions for the first exhaust they made for the z. So anyways i have this system halfway installed on my car for now because the only problem i have is were you bolt up the h pipe with the intermediate pipe. The two lower bolts i cant get to. The brace is in the way. Am i suppose to bolt these two pipes together then slide it under the car as one peace? thanks alot guys

 

Alright guys so i finally figured it out and now its installed. The only problem is when i go around five thousand rpms the car whistles. Wats wrong? please help. And my mods are the injen CAI, stillen headers, stillen hfc and HKS hi power.

 

tighten all your exhaust bolts and check to make sure your intakes are on good and tight.... you either have a loose bolt letting exhaust escape or maybe one of your intakes arent on good and its letting air in where its not supposed to.... GL...

 

okay i found the problem. Thanks ekelly36.


Mods please delete this thread
