I currently have Kooks Longtube headers, Kooks Offroad X-pipe and Stock GXP Mufflers. My wife and I cannot stand the smell while idling. Can I weld in high flow cats to the Offroad X-Pipe?
Yes, just have a decent exhaust shop add high flow cats just after the flanges and before the rear O2 sensors. Look at the Kooks catted x-pipe as an example. Or you can just buy the kooks catted connections pipes which will likely not cost too much more and keep it a bolt on affair.
You may need to have the car re-tuned that as adding/removing cats can mess with some drive-ability things. Depends on the current tune and how "high flow" the cats are.

If the exhaust shop tries to over charge you to weld them in place hit us up for the catted Xpipe. It will bolt right in and you can always sell your off road Xpipe to someone in need. You might even be able to find some looking to trade your off road Xpipe for a catted version if you're lucky.
