My T-4 exhaust and Rev. box along with my K&N filter and Jet kit will be arriving thurs. Will I notice a big increase in power?

 

The difference won't be huge but you'll be able to feel it compared to stock.

 

Like yellow said, you'll feel a little something, but nothing huge. The rev boxes are kinda worthless. They make the quad extremely hard to start in colder weather. They usually drain the battery long before the quad will kick over. Also, they will give you 1000 more RPMs of rev, the motor has already passed its peak power output when it hits full revs, so giving it 1000 more is kind of useless, unless you like rebuilding motors for the sheer enjoyment of getting your hands dirty.


I just put a 416 kit in mine, along with a 10.8-1 JE piston, and a new cam. Talk about feeling a difference. It flat out rips. All for about $300 in parts.
