it ran a 15.8 stock back when it was on the road, it now has kooks longtubes on it its a little charbroiled right now but plan to run it when its back out on the road.
a few companies now make them back when I bought this exhaust set up not many manufacturers were. theres kooks,jbl used to make them they made both longs and shorts.
one good thing with shorties is generaly no exhaust change is needed with longtubes things need to change.
