Speedwerx, SLP or SSI kit for 18 Cat?

[907to406]

Picking up a 18 arctic cat and want to add a little more power. I'm having a hard time deciding between the Speedwerx stage 2 Exterminator kit or the SLP stage 3 kit or SSI's Stage 2 kit. They all look pretty similar but would like to hear from people who have run both or have one of the above kits and why you went with it over the others. Basically looking to add the most power and shed the most weight with reliability being the most important as well as price tag.

I should mention my typical riding zones range in elevation between 6000'-10,000'

Either speedwerx or slp. I have a speedwerx fat daddy pipe on the way. I could not find any reviews so I went by DynoTech numbers.

stock is best

Whatever way you go, all require 2degree timing advance, stock too. Cheers!

I live in Michigan and spend 1 week a year out west somewhere and I did the SSI kit and I'm very impressed. Even 2 local guys ( Alpine WY) tried my sled and they couldn't believe how smooth it ran and pulled hard. My ride is a 19 Alpha 165

I’m on the fence right now not sure what one I want to go with speedwerx or slip also

I went with Speedwerx because they had their pipe dynoed at Dynotech whereas Slp has not. Yet. I have not run it so far so I cant comment on performance.

ive got the ssi pipe mod and y pipe runs great. i put adjustable weights in and at 10k im running 2 grams more than the stock weight for 6 to 8k.
