Note. I welded onto the elbows, not the pipes. Very nice pipes, great fit and shape and finish. Nice and fat. Great sound.

Yes - actually it was your post that made me weary about the Fabspeed pipes, I think the holes you had to plug by machining down those huge bolts is to accommodate the ROW Euro setup that had CO2 sensors in the secondary cats (totally not sure if that's accurate, but I think it is).

Anyhow - the pictures they show on their page don't seem to have the ports you had to plug:




Was hoping there was a third option though...
