Hopefully anyone with shorties can answer this question, but particularly pacesetters. I'm gonna get an offroad pipe custom made, and I know that the y-pipe for the headers would normally weld to the factory cat (that I'm replacing with an OR pipe). Question is, is the y-pipe the exact same length as the factory y-pipe? in other words if you cut the cat off right at the weld between the cat and the factory y-pipe, would the new y-pipe come right to the end of the cat? Or is the aftermarket y-pipe slightly longer or shorter? I need to know so I'll know the measurements I need for my offroad pipe. thanks.

 

Just drive your car open headers to the shop and have them make it with the car in thier posession.

Having a pipe made absent of the car just doesn't sound like too good of an idea to me - too much could go wrong.
