custom exhaust ?

[Tig]

I know they probably wouldnt be beneficial (or would they?) but they'd look pretty slick.
Has anyone made or seen any custom exhaust set ups?
When I get my CR I would like to build one, to be a little different.
What are your thoughts guys?

I'm probably off, but I'm pretty sure that those conical pipes and specialty built pipes are engine specific for the most part, as in the builder of the engine builds the pipe specifically for that motor due to the amount of tuning involved to get the correct performance from that motor. But I would think there are other aftermarket pipes beside PC and FMF also.

theres a formula to make pipes. its probly pointless to make one for stock bike though
