How many of you s/st guys are getting away with open exhaust?
I'm planning on going to the divisional race at CDP this weekend, & I got the car down to 10.83 last sat night, but the weather was better than they're predicting this week.
I'd like to take the 3" tailpipes & muffs off to save some weight & maybe make a tad more power. Do you think I could get away with a big block w / 3" headers & X pipe?
