Not sure about the Yosh, but I know the TA comes very highly recommeded for the 426, especially for a low/mid range pipe. I have one (Thunder Alley) on my 450 and am very happy with it.

Never tried the Yosh and don't plan to after owning the TA. It's an awesome low to mid pipe, and you can't beat it for the price. Do yourself a favor and have it ceramic coated when you order one.

Cannot speak about a Yoshimura BUT I can tell you that the Thunder Alley is one hell of a good pipe. I have a YZ450F and it is a screamer.... It has excellent low, mid and high end performance! You cannot go wrong on this one. Make sure you have it ceramic coated. The pipe is easy to repack too!

As for as dB level - it is loud BUT is "music for the ears" to those who like the sound of a finely tuned 4-stroke anytime during the day.

Something about the sound of a 4-Stroke with throttle cracked open playing the [COLOR=Blue]"Thunder Alley Boogie." [/COLOR] One thing I am confident of, you will not be disappointed with a TA! :naughty:

what is the difference between the regular exhaust and ceramic coated

The regular exhaust is bare steel and takes a lot of maintenance to keep it from rusting. The only drawback to the ceramic is Bob sends them to Embee to be coated, so it takes a little longer. Well worth it though. I've never had mine dB tested, but you can order quiet cores (98 and 96 dB I think) when you order the pipe if you think it might be too loud.

is the TA pipe louder than stock?

  • cowboyona426

Yes, but it's not make-your-ears-bleed loud like some pipes are. I would guess no less than 99, no more than 101 dB.

They are louder than any other pipe out there! I like the sound, though I dont run one. If you are in an area with sound restrictions, it might be a problem. Well built and reasonably priced.
