GYTR Slip on muffler

Installation was a breeze. Bolted right on in place of the other aftermarket muffler that was on the Raptor 250. Love the exhaust clamp that was included. Sound is more like a performance 4 stroke vs Obnoxious of the other muffler. Performance, awesome midrange hit. Wants to pull the front wheels!

This pipe really woke my yfz 450 up compared to it having a stock pipe on it, very nice for the price.

A: Most aftermarket systems sound pretty much the same. Some have a deep sound and some, after a few miles, have a raspy sound. Some will have a different tone and even the same exhaust system can sound differently on different models of motorcycles. In general most systems are around 92 to 98db's.
If you run your rpm up to the rev limiter the db's may go as high as 100 to 102+db's.

A: It is compareable to the db of a stock pipe with core removed. Except it takes some of the annoying sharpness out. With this pipe you can keep the insides in tack of the muffler and sounds great.

A: Normally when installing just a slip-on exhaust only little or no rejetting is required. You should be safe to install the exhaust and see how your bike is running and then adjust and tune the carburetor from there. If your bike is jetted correctly now you shouldn't have to make any major jetting changes if you were to run this slip on.

A: Maybe move the needle clip down a notch or two. I used the powerbomb header ant went from a 160- to 165 main jet and got a bigger noticeable PULL when racking through the gears.
