I'm looking for a pipe for my yz450, to ride on the trails. I has the have a spark arrestor and meet the decibel requirements. Any suggestions? Brands? Models?

I currently have a White Bros E2. Im very pleased with it. When I had my WR250 it had a FMF Q. It was also very good.

Whats the difference in power compared to the stock pipe. I was kinda leaning towards a white bros pipe, but I didn't know what kind to get. I don't know very many people with them.

Cant really tell you the difference with the pipe alone. The reason is I also removed the smog pump, backfire screen, installed a JD kit and did the pipe at the same time. Overall the bike runs alot smoother with no roll on burp. The power is now clean and strong all the way through. I dont know exact numbers but its nowhere near as loud as a stock mx 4 stroke.

One last thing....The E2 allows you to insert different tips. It comes with a spark arrestor and track tip but you can also purchase a quiet insert to drop the db's even more.

What about pro circuit and yoshimura?

I think I'm going to go with the pro circuit T-4. Anyone have this pipe?

Get a WB aluminum Pro II pipe. Great power gains and they come with the SA insert
