is there alot of difference and does the bassani offroads have 02 sensor plug ins?

 

randomtechnology.com claims their cats flow as well as straight pipes. I'm thinking of running with Brenspeed's offroad H pipe for a while, and if the fumes are too bad, maybe having some Random Technology highflow cats welded in or something.

 

I have the x-pipe with removable cats. Both the high flow cats and straight legs have holes for the sensors to screw into.

 

yeah - the sensors slip right in and the cats will quiet the exhaust a bit -

 

I'm running Bassani's X-pipe with cats on mine. I don't have the harsh fumes everyone keeps mentioning. I added a little "exhaust sealer" at the connections when I installed it. No problems or fumes 2,000 miles later.
