anyone ever tried a header form a different bike?

I keep seeing these streetfighter kz's with exhausts ive never seen. Im looking for a more upswept exhaust, more upswept than a vance and hines header.

Sometimes what your seeing is a Kerker or V&H pipe with a modern can adapted to it. A friend of mine gave me a Yoshi competition baffle which I (I'm a mechanic and do exhaust work/ pipe bending) adapted to my Kerker. It comes off the pipe and is much more upswept than the Kerker. I switch out the mufflers now and then.

I put a Yoshi pipe on my 550. It was originally for a 600 ninja so i had to do a little modifying. One thing you need to watch out for is the passenger peg, I had to cut the pipe in front of the canister and re-weld it to lower it and to clear the peg.
