Full systems

What is a recommended good full system exhaust? I don't want to spend tons but I imagine the stock system is restrictive.

Assuming it Pregen, I think Muzzy is the only full exhaust readily available now. Two Brothers and Yoshi are slipons but wont do much for performance. To my knowledge, any exhaust will require a rejet.

Even Muzzy has stopped producing their pregen full system. The prices now are low, get on it ASAP and get one before they're gone. Your only other chance is eBay. Good luck.

Rejetting isn't hard. It's worth it when you get it right.

I found it at Star Cycle USA WWW.starcycle-usa.com. I got it the next day.

So the best guess for jets would be factory 110 mains or 108 mains. This is what I have seen others run. Anyone with experience with this?

Stock jets are 105. Get a set of 108 and 110 and 112 and test them.

With a pod filter, I'm happy with 110. It's definitely better at 75+ degrees outside, so I likely could go to 112's if I wanted to. But it's a summer toy so I'm not worried about cool weather performance.
