Runnin Stacks?

RE: Runnin Stacks?
if you want a semi get your cdl's and start trucking. personally i think that stacks on a pick upare the stupidest thing ever. i wishthey would outlaw them everywhere.
EDIT....sorry i dont usually post things like that. i just get mad everytime i see a truck with stacks in the bed. especially the guy that lives across town with a stack on his v6ram.

What he might be talking about is how the new diesels have the particulate filter near the tip that burns off any soot in the exhaust so that there is no more black diesel smoke. You can't convert this type of system to stacks from what I recall. I doubt this applies to the older style exhaust systems.

You can run stacks in any state but on the black smoke issue any desiel that blows black smoke is just wasting fuel and the black smoke is a resalt of the exsess deisel being burned in the exhuast manifold not in the cylander. This has been proved by Gail Banks.

im thinking no back pressure. and you need some.

A common misunderstanding is that too big of a tail pipe hurts performance because there's no back pressure. What actually happens is the pipe expands too much and the gasses cool and slow down before they exit the tail pipe and cause turbulence and bottlenecking in the system. What you want is the right size of exhaust tubing to get the gasses out at the correct velocity not too small to cause backpressure, not to big to cause excessive cooling and lost velocity. As you build up an engine, you actually might gain performance by stepping up the size of your exhaust system. I saw a chart somewhere that had recommendations for exhaust diameter based on what HP you were making at the crank. Something along the lines of 1/2" increase for every 100hp made over stock.
Another good way to keep velocity and improve system scavenging is to have the entire exhaust system ceramic coated inside and out. It isn't cheap, but it'll net you some gains over a plain system.
