I put in a good weekend or racing and riding with my new Thunder Alley Pipe installed on my '06 450. I have to say that I am very happy with my purchase. I didn't expect anything less, because I have been happy with these pipes in the past.

Just as I hoped, it added a blast to the lowend. I think the '06 is a little soft down low with the stock pipe. The bike now has a ton of smooth power from crack of the throttle to the top. To me, this makes the bike easier to ride. More power down low = less downshifting in a corner.

Best of all, my exhaust does not reach to the end of the fender now. At 250 bucks, this pipe is a real bargain in a world of 600 dollar plus exhaust systems.

I agree. I had a thunder alley on one of my 426's and loved it. very nice throaty sound too. Very good pipe at an even better price.

Yes, it is the slip on. I don't have any pics of it yet. It does look nice. I will try to take some.

I ended up getting a DMC pipe for mine it will be here this week, although I am not "supposed" to ride till July because of My ACL replacement.

I agree that the 06 is softer than my 05 for sure, I had the head and carb done on that bike and the TPS sensor disconnected, it ripped but the 4 speed required more bottom end than the 5 speed seemed to.

The longer head pipe of my 04 Carbon pro that was on the 05 helped the low end response, I ended up with a shorter head pipe on it which helped over rev a bit but gave a way some bottom, but it had some to give.
