Home brewed stacks

Hey, I've just scored a quantity of 4 inch and 6 inch stainless tube which polishes up luvvly, so I thought I might make me some stacks. The plan is to take a branch off on a Y piece before the cat with an electric valve to open and close the route to the stacks, so I can go back to quiet and testable at the push of a button. (Anybody done this and does it work OK?). From the valve at the Y, a bit of flexy then four inch up into the bed, split it into two and out to two 6 inch slash cut stacks.

Fabricating all this is a doddle (I'm a bike builder and cut and shut stainless pipe every day) but I've no idea what it will sound like. What other issues might I face? I'd expect lower exhaust temperatures and a faster spooling turbo, but is there any down side?

Dammit, I just realised I posted in the wrong section, I'm running a 1995 7.3 powerstroke!

It should sound awsome. The OBS's sound great loud.

It's likely to take a while, as I'll be fitting it in between earning jobs, but I'll post up a video when it's all hooked up. Should look great, as I have an alloy chequerplate tonnaeu cover on the bed, so the stacks can stick up through it and the pipes in the bed will be hidden.
