    • Yeah the exhaust they made had a 36mm ID muffler section, loud! I made a baffel to go in it, I've now reduced the outlet to 10mm and its getting better.

    • Mint !

    • A large diameter headpipe will give some improvement at higher rpm at the cost of low end torque.

    • How bout a 12 - 15km/hr loss in acceleration over the same distance

    • Yup, I could see that being possible

    • Well the lesson here is, if you want something done right do it yourself.

    • Yep that way to big

    • All for the low low price of $300

    • Anyone measured the inside of the standard pipe?
