Drop me a line when you're selling.
I've got a tubbs modified pipe which I like, the bike runs very well with it on but it is starting to corrode and is also kind of heavy.

I know this may sound a bit daft but........ wouldnt the forward motion of the bike hamper the escape of the exhaust gases ? I assume the can comes out at the front ?

:headbang:

think about it Rob, the outlet is at 90 degrees to the airflow of the bikes tavel, if anything it will create a partial vacuum in front of the outlet :idea:

1. I wish I had a shed to be cold in
2. I wish I could make things like that
3. That just a piece of practical artwork. Truly amazing!

dyno plot for the reverso and my straight thru can, blue=reverso, green=straight thru, red=standard, not massive gains but a good midrange boost with reverso with no other mods. Image
and first pics of my new headers, still needs a few tweeks Image

Guessing from the frame colour, it's a xb9. Would fit the numbers too.

I think it is a 12. Saying that I know a dyno where it will make more than 100 and make yours look down on power ZB ;)

it's a 2008 12, that dyno is pretty conservative, i'm not overly fussed with total output just what gains i can get :)
