    I had several other mods to match up with the toomey pipe. But I believe the toomey pipe really brought it all together. It is definitely more of a top end pipe, but boy does it scream when those rpms start to rev. Also, the sound the toomey adds is amazing. BRAAAAAAAAAP!

    Fit tight, lighter than oem, looks good. sounds the same as oem, a bit shorter which is no issue. Not as thick material as oem on canister and will dent much easier but that's ok

    Nice Silencer

    Spark arrestors are required where we race, so we own several of these on various bikes. The Turbinecore didn't seem to tax my son's 65 much and kept us legal. We did get a little spooge out of it, but I probably could have jetted it out. Wasn't enough to cause concern, bike ran perfect.

    Like New1

    I bolted this on and WOW , just like my bike was new again. So responsive and toque. I had and old FMF sparky I was repacking for the last 10 years but this is 2x better. Turbine core Q series blows the old one out of the water. I would recommend this for sure a good packed Silencer is worth its weight in HP... Brraaapp ON

    Got this for my yz125. Makes the bike sound crisp plus improves the mid range a lot! I loved shorty silencers but after switching to this I'll never go back!!
