TCI Streetfighter C6 with the TCI Saturday Night Special converter
2 1/4" exhaust all the way back through Flowmaster 40 series mufflers.
Stock DuraSpark 2 ignition system
I'd like to get closer to 9.5 et in the 1/8 mile. Any suggestions?? The 2 1/4 exhaust is going to be upgraded to 2 1/2 or 3" soon. Will I see any noticable gains? Is the 2 1/4 holding me back? Any other ideas how i can squeeze a few more tenths???
