i was curious has anyone messed with it? i mean the flap opens past 4 grand in what i have noticed to be 3rd gear and on. just wondering besides the sound increase is it worth to leave open or just base it on preferance.

 

Its a common mod on all the older models. I dont see why you couldnt try it and see.

 

actually i have tried itand only noticed the exhaust note increase in the lower revs.
