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!
