I no another exhaust question but im not racing just trail riding. Just got the gytr ecu and tuner kit. Should I get the

Yamaha Quiet GYTR® Performance WR Muffler Insert to be used with the stock exhaust system to offer a power increase while allowing your muffler to pass the 96 dBA 20" stationary test.

OR

Yamaha GYTR by FMF ® PowerCore ®4 Muffler

From what others have said the GYRT insert doesn't offer much over stock. If your looking for the best power gains, go for the FMF.

I am a "new" 07 WR450F owner and from what I'm reading the adjustable Lexx from RMATVMC sounds like the way to go.
