Anyone had experience with this exhaust? I haven't installed it yet, but from what I understand it's REALLY quiet(88db)- I can see why. It's about 4-5" longer than the stocker and the riveted-on endcap is only 28mm diameter- much smaller than the modified stocker or HRC tip. Imagine it doesn't allow the bike to breathe very well... Just wondering if anyone's experimented, maybe shortening it a bit and using a bigger-diameter endcap? I don't want it to be too loud, but I think it could gain a few dbs (say 93-94) & still be OK. It'd be a shame not to use this- it looks to be very durable & high quality. Anyone??
