It rips!

I bought this exhaust to replace my stock CRF exhaust. I wasn't sure if I'd need to rejet the carburetor, but it runs great. It fires right up on cold starts and rips.

Questions & Answers

  • Will I need to re-jet the carb on my brute force to be able to use this?

    By: Logan

    Yes, we always recommend re-jetting your machine when changing intake or exhaust components, especially if it's a completely stock unit.

    For Pro Circuit exhausts, we recommend Dynojet carburetor jet kits as they come with a range of components that'll help you get the most out of your new exhaust.

  • Does it come with hardware bolts etc.

    By: Lisa

    Typically, these exhausts only include hardware for attaching the header to the muffler. For everything else, you are to re-use the OEM exhaust bolts to complete the installation. So long as you have the stock exhaust on your bike, you should have no problem fitting this exhaust to your machine.
