Hey,

I was just about to enter into an exhaust project and did a bit of digging around...

Have a look on eBay there are various things I found that may help. there is an exhaust pipe firm that will cut any size pipe to length and slot if for you (not kill it I mean stick four slots in each end) there is also a firm that sell flexible links that would get you a nice turn....

saves on the potentially costly solution of having someone custom design and bend one for you...

Not sure how long the flexible ones last but I had a set up front on a big jag and they never failed...

A good cheap way to at least test the exhaust before you have one made.

let me know if you can't find them and I will stick up links for you.
