Are there plans for a full exhaust system for the rhino?
and what type of hp gain do you typically see from a slip on to a full system?

[KEVIN/HMF]

No Plans for the full system, but any decent header should ad at least a 3 hp increase.

Any chance the grizzly head pipe is close, or possibly could be modified to fit the rhino?

[KEVIN/HMF]

The Grizz and the Rhino are completely different and won't match up...sorry.

I purchased the Eco slip on for an 05 Rhino, the instructions say to use a 175 main jet, which was not supplied with the kit. The factory is a 150. I primarily ride in elevations of 5,000-5,500'. Now that I will have to purchase a new jet, should I purchase a smaller one for the altitude, possibly a 172 or maybe even smaller. I re-jet my two stroke frequently but have never jetted a 4 stroke for elevation. Any info would be good. Thanks.
