Hi Gavin.

Blimey, that's cheap!:

Mind you, it'll be mild steel, not stainless. Should give you an idea of what's required.

The Jetex website lists all the bends, straights, over-axles, etc bits you can get should you want to make one up yourself, and then it's a case of joining them up!

It's worth keeping a constant cyber-eye out for companies who make up systems to order; by the time you get to that stage, you should be pretty clued-up. They CAN vary hugely in cost.

One major advantage with a side-exit system is the increased ground clearance it offers. In fact, my Marlin will soon gain a side-exit system for just this reason. The current exhaust was hardly in brilliant condition, but a couple of sleeping policemen have made sure it won't see the upcoming MOT test!

Your 3" system sounds (oops) a bit loud, tho'.

I'm going to experiment with a 'Polyzaust' (I don't think that's spelt correctly) I bought of Ebay. Have you heard of them? It's South African, mainly Stainless Steel, but with a polycarbonate outer case - yep, it's made from plastic! Meant to have very good sound insulating properties, and is smaller and lighter than equivalent metal boxes.

We'll see!

Oops, that link doesn't take you directly to the Cortina systems. However, the 'search' facility on the left of the page will get you there!
