I've been generally unhappy with the aftermarket part availability for the XT. With only one cat back out there I thought I'd try something different. SPT recently came out with one for the WRX at a very attractive price. It's made by Bosal and is a full 3" stainless except for the neck down to the stock center section. I gambled that it may work out or I would have to modify it. I found one for $350 shipped and bought it.
Well it doesn't bolt on. It was delivered with a hanger arm bent 45deg. And the one on the front of the can was welded on backwards by the South African welder. I checked it's backwards to the WRX as well. Must have been made on a Friday. When I tried to install it, the tip was on the bumper cover and the pipe was very close to the CV coming out of the diff.

Since it's SS and I don't TIG weld, I took it to a welding and exhaust shop. About 45 minutes later and it was done. They made a nice triangulated mount. Not shiny but who gets down on their hands and knees and looks at the hanger arms anyway?

Money shot:

passenger side hanger arm:

Fixed front hanger arm (plenty of room for a larger anti-roll bar):

Pipe with plenty of clearance over the diff. Still 7" of ground clearance. I'm very happy with it, especially at $350 + $50 welding and installation. Sound is aggressive, it being an upgrade for a WRX. It may be a multi chamber design but it definitely doesn't have any wool in it.
