im looking for a second hand exhaust system for z33, fujitsubo or HKS, full exhaust system that can withstand a turbo or supercharger.
thanks for any help.
when dis happens my rev feels like a pull back, drop of performance for 1 sec,,,, on dyno machine at each run, it always happens at dat region, thus im not able to pull above dat region, as da a/f ratio fluctuates up...
