What are the best pipes to look for, for 1/4 tar racing. They would be for a 800. Only ones I find brand new are aaen pipes. are they any good. I only ride on the tar my sled is winterzed now.

I've had aaen and psi pipes for 90* firing. The testing I have done The psi were superior. If you 180* he mooe howlers or a hybrid r the only way to go IMO
