Was just curious about some performance aspects. By now, there should be enough pairs out there on running cars to determine how these perform. All cars/combos will be different, but keeping in mind this question is relative to your engine and what was previously there for exhaust. It would be interesting to get some sort of feedback.
I haven't fired my motor yet with the Doug Thorley's on it. I really won't know preformance because I have nothing to compare it to.
If somebody will buy me pair I will swap them out for my Hedmans and do a right up and dyno pulls No really, I am serious
