It works really good, people say there not always accurate but I have used it for a long time and I have a 300 dollar GPS unit and they both read the same thing when I'm going so it must be accurate. It is very easy to install and it comes with directions. Minor Work, and I don't got alot of money for a full system so what do you think is the best Slip on System that I can get and how much is it? thanks for the help guys

I took my snorkel off, adjusted the valves, took the innerds out of the muffler, rejetted and it made a world of difference, really woke it up. I read a dyno post and a guy found out that after a lot of testing the stock muffler with the innerds removed was about the same HP gain as a slip on.

Mine was in like glue as you said also, when i had my stock muffler on i took mine out but completely twisted the thing (not my exhaust, just the baffle. I undid all the bolts I could see on it, and put a pipe wrench on the little tip and twisted clockwise while somewhat pulling out, it came out as a complete peice but there was no way I could re-use it if I had to.

I just did it for a deeper sound.

You might soak it with wd-40.

Mine was rusted in place. Had to use large waterpump pliers to "flex" the tip and loosen the rust. The arrestor was toast by the time it came out.

Anything you can do to let it "breathe" better will improve power.

I tried to take it out again today and man its so hard to get it out. It just won't come out. When I do get it out will I need to rejet or anything. Its all stock and would just have the baffle out. Will it hurt my quad and can I get into alot of trouble having it out. What will the DB rating be
