Supertrapp 2-1. Makes great power for stock size motors and you can adjust the level of sound from almost stock to louder than you want.

 

You'd be surprised what the stock exhaust will flow for HP.

Hell, even just gutting the CAT out will loosen up some flow without adding noise.

 

Ayden, hello old chap, from a couple of counties away! A basic problem with aftermarket exhausts is that many of them subscribe to the "loud exhausts save lives" mantra, not something I for one believe in. There are indeed options available out there, as mentioned above, indeed I have a SuperTrapp Supermeg and it really is a great system. Gives a wonderful torque curve and decent subdued sound, the unexpected bonus being it also made my bike remarkably smooth running. So if you want an instant recommendation, that is mine. I have an S&S 107" Evo engine, giving over 100/100 - it's great!

 

I'll think you'll only be able to stage it to a 21/32nds and still keep it quiet

 

 

 

Easy man, anything can be accomplished. Don't you ever get rid of that Rocker C, unless it is to get another one.

 

 

I loved my 2008 so much, that I sold it and bought the final year a 2011, and modified it to suit me. It is most assuredly a forever bike.
