for anyone wondering the stack is functional and made from an automotive test light tube and some plumbing fittings at the hardware store for less then 10 bucks things that are an absolute must to not ruin your engine everything added to exhaust must be same size or larger that original exhaust tube anything smaller will restrict the flow throw off your tune and fuel vacuum and possibly melt your piston again these guide lines are not an option you must go bigger on all pipe and fittings for this to work you burn up your motor by not listing its your own fault if you do it right you get a pretty sweet diesel look with the smoke coming out the top of the stack oh and under no circumstance bend the pipes or fitting this will pinch off the opening and cause same problem and too small of pipe

check out my profile for the pics of this set up to see how it works and how it looks since this thing wont let me post url pics yet
