Yoshimura TRC Pro Series Carbon on CRF450!

[mudman21]

I have just installed a Yosh TRC Pro Series carbon "Full" exhaust on my 05' Honda CRF450. After my first ride, the bike feels sluggish. The stock pipe feels much more powerful especially in the bottom & Mid range. The Yosh pipe will rev out a little more but this is very dissappointing. Does anyone have any jet recommendations or fuel adjustments with this pipe installed? I am at an altitude of 0-1000 ft. and the weather here is very hot & humid! Any help would be greatly appreciated!

Just an update on the Yosh Pipe. Ordered a Dynomax Stage 1 jet kit and installed per their instructions. WOW!!! What a difference. I tested it and had my first ride today and power improved everywhere. I was whipping the berms, hitting the big jumps out of the turns. I am more than happy with the results.
