how much power does a cutout rob from you when closed?


they got the TSP true dual system now with sweet thunder mufflers... alot more restrictive then the average Bullet muffler thats for sure..


and I happen to have a pair of 3inch hedmann cutouts, for racing I'd probably have it open (especially when this car gets the cam) but for daily driving how much power am I losing for having a cutout on there?
