V.A.L.E. slip-on/full exhaust systems and flange-on systems feature CNC machined aluminum inlets and outlets. These special designs provide for ease of maintenance as well as simplified construction, which is what a premium performance product is all about
The exhaust note produced by all Top Level exhaust systems is best described as being deep and throaty without suffering from the shrill whine normally associated with other manufacturers straight through muffler canisters

Awesome beefy sound - NmistRecommended by Reviewer: Yes
Pros: Super beefy sound without being overwhelmingly loud. Looks awesome. People think bike is modded or bigger than it is because it sounds as loud as most 600 bikes.
Cons: Draws a lot of attention. Gives authorities the impression you are speeding.
Great exhaust kit. Came pre-installed on my bike by last owner and I would buy it again in a heartbeat. Amazing sound. People will not know its a slip on by the great sound quality. At 10,000 rpm you can hear engine whine but it is very minimal due to how loud the kit is.
