Reviews for Pro Circuit T-4 4-Stroke Silencer
More power better sound!
Bought for my '95 KLX650R and am very happy. I replaced a cheap aftermaket silencer that rattled. Huge upgrade! Fit perfect sounds awesome, and better power.I would recommend this item to a friend.
this was well made but the T-4 4-Stroke Silencer Part #448937 didn't fit my stock 2001 drz400s head pipe, It looked well made but i sent it back , Not sure if a different part number would have fit. I ended up just getting a full system from another maker.I would recommend this item to a friend.

Put on 03 wolverine sounds nice and throaty and not too loud . nice machine welds on canister - welds on mid pipe not so nice . fit well but had to cut a slot on end of pipe so hose clamp could compress the seamI would recommend this item to a friend.
Good sound, good power. Quiets down considerably when at cruising speed. I needed to re-jet but that helped with power as well.I would recommend this item to a friend.
It´s very good exhaust, good quality, good performance. Too much better than leovince or FMF.I would recommend this item to a friend.
