I have heard of him and he makes awesome pipes. Hands down the best for the YZ 426/450. They have that handmade factory look.

Yes, I rode a 426 with one. Mine was stock and another friend had a full white bros system. The t/a pipe was incredible. It built revs faster and screamed from the bottom to the top. I really liked it. I was going to buy one for mine but I sold it to buy the Predator.

do you think it would be a good pipe for the predator or something else?

Absolutely. I just don't know if they make them for the Predator. It is a pretty small shop in Hanford, CA. But since you live in Tulare you might know that. I think they have a websight, you may want to e-mail and ask.

Is the t/a pipe louder than the stock one or are they close?

I haven't heard one on the Pred yet because they haven't made it. They said they're doing it soon. But it will probably be louder that stock.
