Has anyone put after market exhaust on yet? I heard one today with the two brothers WOW it sounds great. I want to put one on just not sure witch is the best. anyone know how much of a gain the two brothers will add.
we did not have to do any jetting, and it was a very easy install. it is louder than stock but it is a deeper sound. the cab of the Teryx is loud from the engine, i did not think that you could hold a conversation while wide open with the stock exhaust, but the aftermarket is louder...
we made our own tip for the exhaust and it did make a difference. some claim it adds a 3hp gain. so for a chaeper upgrade the tip would be fine. but the gibson is a big improvement..
we are a dealer for gibson, and also have some tips available.
