What about the supplied muffler with the Evo 60NX? Is it really way too restrictive?
thanks,
Ernie
Not really restrictive, just lacks a few things that add power. Volume can help, such as what the discontinued Tower muffler had. The most power can be made with a Macs tuned pipe followed closely by a quarter wave tuned Evo muffler, aka Jett. Bang for the buck, compactness and simplicity, the Evolution TUNED muffler rules.
