Has anyone installed the speedwerx slip on exhaust on there quad?
Does anyone have a clue of how good the performance is?
How loud is it? I am looking at one for my 500 Cat but everyone around here is running the HMF setup so I dont one to check out.

 

I have one!!!!!

You will be able to tell a difference in the performance, but Speedwerx doesn't make claims as to "20% hp increase" or anything like that because those can be false advertising. Mine is right at 96 dec, which is the legal limit in MN. It is a tad quieter then the HMF. I am very pleased with mine, and give it a thumbs up. I have even been down to the Speedwerx shop and they are great, honest guys. Feel free to call them and ask them your question too, one thing they won't do is sell you something just to sell it to you. They make sure it is good for your setup. Ask for Jeremy. Good luck.

 

Hey Catterman, you say you have clutch rollers for your H1, do they make a difference and how and are they very hard to install, what I mean is can a schmuck like me do it in my garage?
