  • 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?
