what would be the better exhaust a pro circuit t-4 or ti-4, or a yoshimura rs-2 exhaust?

wow thats a really good deal right there! how has it worked out for your crf?

I really like it so far. Fit & finish is phenomenal. Dave (I believe his name is) uses top quality materials & excellent craftsmanship. He also has excellent support from what I hear. I haven't had to contact him besides the original order, but his reputation precedes him.

I got the procomp with the SA & quiet core. It didn't quiet it down much but the sound it makes now is excellent. I did notice a slight low-mid grunt increase on the butt dyno.

My only complaints would be I don't like the end plate of the can as it's machined out and it can sometimes be a pain to clean. Same deal with the rear bracket that holds the can to the bike. There is a machined out cavity that can pack with mud and be a pain to clean.
