Beautiful handmade carbon fiber muffler with Titanium inner pipe.  The header pipe is built in durable stainless steel, so it will not dent or ding easily like titanium header pipes do when hot.  The carbon fiber header guard is designed to cover the entire exposed pipe area all the way back to the kickstart lever, so no more burned pants!  All the hardware is of the highest quality: stainless steel header retainer spring with billet spigot mount, titanium mounting hardware for both points, plus high quality mounting brackets where necessary.

This exhaust system has so many benefits:
Saves up to 3 lbs in weight from the stock system
Increases power noticeably thru the entire rev range
Allows for easier starting, less engine braking, and freer revving motor
Better sound - quieter at idle, clean healthy sound thru rev range, no "slap" noise 
Looks gorgeous and did we mention it's Hyperlite and sounds amazing?
