for a stock engine you dont need headers. if you run true duals from headers back, it will sound like complete ****.

how is true duals from the headers back gonna sound like complete crap? we've done it tons and it doesn't sound any different then normal.

As for them headers, kinda high on price and can't tell if they are long tube or shorties. The pic shows long tubes.
