I installed my OBX Longtubes last week, easy install.
I added 3" inlet/outlet high flow cats to mine and cut out the little 2.5" section on my Flowmaster catback so that mine is all 3" now. Welded it all up myself...very pleased with how it turned out.
Oh, I also lengthened my front 02 sensor wires, little solder and some wire.
Saved $800 compared to Kooks longtubes with cats.
