You need to rejet with any pipe on any bike. Its simple, you let more air in or out of the engine and you need to compensate by letting more gas in (jetting) You will have to rejet!!!

Well you dont have to, but why wouldn't you? If you dont your quad could run worse than before. You got the pipe to get more power, your not going to get it unless you rejet!

Ok thanks i have the complete HRC kit and i was just wondering if i would need to re jet with that i wasnt completely clear when i got my HMf for my warrior i called hmf for what jet to run adn they said it wasnt needed so......

That doesn't sound right. HMF has to be one of the worst jetting recommenders I've seen. Every pipe they sell they recommend a main jet WAYYY too large. Ask around on here you should be able to get some answers. What type of riding are you doing? You have the HRC kit? Do you have an air filter? Full airbox lid? HRC lid? No lid? More info and we can give you recommended jets.:D

HRC kit full so lid and intake kit uni filterwith a hmf slip on lol any more ?'s let me know.

I'm running the HMF elliptical slip on on my 05' with a 170 main and hrc stlye lid. runs beautiful.

[400exrider707]

Try 175 main, 50 pilot, needle I've seen vary a lot between four wheelers and I dont know why. If your using the HRC needle, then try 3rd clip down first and see how it runs. If it stumbles keep bringing it down till it runs good.

Well I got it and got it on and there was no jetting required what so ever with the 185 in there it runs great through every gear at every RPM very pleased with it.......will post pics later on!

i like mine.

[450robot]

i think the eliptical shape is there to allow clearance between the tire/axel and the exhaust can, so there is no rubbing or denting... which seems to happen alot with my 20inch holeshot hds and stock exhuast

maybe i should look into one

[IOWAracer]

I highly recamend it rode with it today for the first time and it made my 450 with the HRC so much more useable in the woods im not even joking i love this pipe its actually quieter then i exspected as well.

[d3ktrix]

So does the elliptical have any performance differences compared to the round 1? Or is like mentioned above, just for clearance and looks?

[MMcCannon]

HMF Elliptical vs Round ?

That thread should answer any ?'s. The sound and db's are different. Elliptical is deeper but quieter.

[IOWAracer]

The elliptical is not deeper at all compared to a round HMF i rode witha guy just the other day taht had one and it was a hell of alot deeper then mine they are actually boutt he same loudness too....

[MMcCannon]

I wasn't for sure, that is just what I had read in the other post about them, I want to ride an elliptical so I can know which I like better for sure.
