So far I have a big gun exhaust, epi clutch kit and 26inch mud lite xl tires. I was thinking about trying a k and n filter and maybe a dalton clutch kit. I was wondering if anybody has tried these mods or has any other mods on there outlanders that have worked well. The reason I am thinking about dalton clutch kit is because it has weights, primary and secondary springs. The weights are apparently adjustable to accomodate for oversized tires. It looks like a better kit than my epi. My epi kit works pretty well but with the oversized tires it tends to sqweel the belt a bit when I'm trying to get going in heavy mud and I also lost some top speed. I would definetly recomend the epi kit for stock tires but it has'nt worked too great with my oversized tires. Well any info would be much appreciated.

 

How much of a difference did you notice with the big gun? K&N has a jet kit for the 400.

 

I did'nt notice much for top end power from the big gun but I noticed a little more low end and midrange power. I find my bike now gets up to peak rpms quicker and it holds the rpms better on hills and tough going. I would say its a decent add-on but it was a little on the pricey side. The exhaust is also a little on the loud side in my opinion as well.
