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.

Yrep, get the FMF PC4 and get the 96db QC insrert. Good power and reasonable noise level.

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