This is good info, thanks. I am assuming the before / after 139mph was without an increase in power? (not sure if you just did an exh change only or more work all at once). As an increase in power could compensate for any drag added due to the removal of the rear OEM muffler.
Has anyone fitted an after market exh system (cat back only) and then run at the drag strip pre/post muffler removal? That would be a good indication if there is any truth to the added drag (assuming weather conditions were relatively consistent etc). Thanks.
