im surprized after riding my sons 06 yz 450 just how much softer it is in the bottom end than my 2002 yz 426.
IT does however have a pretty good midrange .. And seems very smooth and linear compared to the 426 also very light in the front end , it has brand new 08 shorty exhaust ,newish piston 12 hours old, and racetech suspension front and rear it does handle beautifully though when compaired to my old tank...but hey i love my old girl she makes my heart race:thumbsup:

It's obvious that someone upgraded to a new '08 from that '06. They kept the '06 pipe and sold your bike with that POS '08 pipe.

I took my '06 pipe and put it on my '08 too but I couldn't stoop low enough to sell the '06 that way. The original bikes power was way too good to ruin it with that junk pipe so I bought a second '06 system for my new bike and sold my '06 with it's original exhaust and a clear conscience.

Do your son a favor and find him a stock '06 exhaust system for his new ride.

yeah thanks guys, we know that someone switched pipes, as we brought it off a yamaha dealership it was owned by there workshop mechanic and they told us, we also know its a shit pipe but as hes only raced 1 other mx before and that was on his yz 250 2t in the wet.. we thought we would leave it on for now untill he gets a bit more experience under his belt...I was just surprized the difference that it made
