2001 Yamaha Raptor 660 - Pipe Help!

[raptor1660]

Hello im looking to order a full system pipe for my raptor 660, im looking between a curtis sparks, and an hmf comp seires..I want a power gain but am looking manily to make it alot louder...Just some input would be great! What kind of jet kit will i need to get with the sparks and what for the hmf im in SD so not high elevation! Thank You!!!!

both are good systems and so is muzzy. probably have to contact muzzy via email due to no listing on their site. as far as jet kits, the exhaust manufacturers will offer a basic, intermediate and competition kit. add another 50-150 bucks depending what you want ...

I STRONGLY recommend Sparks... Personally, the only single exhaust I'd ever run.

I have heard pretty good things about Muzzy, I just have no experience with them.

Muzzy exhaust sound great. Especially on V twin motors. They have a very unique growl. They are on the expensive side
