1985 Chevy Truck OPEN HEADERS?

I dont advise it! It is incredibly loud and you are goign to get the neighboors mad. And if you fly past a cop like that your sure to get a ticket.

Plus unless your running full open throttle it will decrease torque. Backpressure is good for torque if usually vehicle is operated in the 1,000-3500 rpms.

If your reading about burning the valves dont worry about that. It is not true that you will burn the exhaust valves from runing open headers. Open vs a true dual 2.5inch is nothing. If you put a xpipe or h pipe system itll push more horses then open and its legal.
