ive run open headers at hte track(uniongrove, w/o nitrous) and recieved a .1 second increase. I reset and let hte ecu learn to the gas station and back(15 miles) There is virtually no restriction in our exhuast, and it seems to be give here take there.
Phil,
Possibly the 0.1 second resulted from practice gained as a result of the previous runs ! On second thoughts I am not sure if you by "increase" you mean an improvement or a longer elapsed time and therefore decrease in performance!?
In any event, the above should be shouted out loud from the roof tops, included in the How Too section as a "How Not Too" and posted in Mod Mania for good measure.
I have always been confident that the stock exhaust system is obviously well designed and is in fact a carefully tuned system and that anything fitted by an aftermarket exhaust shop will be an absolute downgrade.
Congratulations, Trevor
