      What's the difference between off road and catted x pipe? Also what would be more efficient for daily driving? I already have roush axleback installed so which one would suit it more ?

      • The Kooks Off-road X-pipe will not include catalytic converters. The Kooks catted X pipe will include two high flow catalytic converters on the mid pipe. Both mid pipes will increase flow and performance from the stock applications. The Catted mid pipe will a little bit more mild tone due to the catted application. https://www.americanmuscle.com/kooks-catted-xpipe-2011gt.html

      would I be able to add cats to this x-pipe for street use

      • I am pretty sure that you cannot add cats to this. They do offer one with cats though

          Killer exhaust

          Combined this with kooks headers and the borla supersnake ovals for your 5.0 and it made a unique tone

          Amazing

          If you’re looking for that race car sound, all while increase HP and torque. Look no further that the kooks long tubes and off road x pipe. At cruising speed it’s quiet, but once you jump on the throttle it’ll scream like nothing else.

          Nice and loud !

          Had a catted x pipe before , a little louder nothing crazy. Switched over because of my 2 step. Didn't want to dump a bunch of gas into my catted x pipe. Love the sound. Great quality as always!

          I had this along with the kooks 1 7/8in long tube headers installed and let me tell ya it was worth it! Worth every penny. This takes your mustang to a whole other level. If you want your mustang to be heard on the streets than this product is for you!

          Great fit great sound

          The x pipe goes with headers fits great and sounds even better. If you like loud without drone on the highway then this set up is defintely the one you want. I have this paired with a roush axel back, and it's defintely one of the best sounding coyotes out there

          Kooks headers and shorty off-road x-pipe combo

          Went with this product based on what I've heard about performance gains and it certainly didn't disappoint. A difference you can feel! Car pulls so much better throughout the powerband and sounds amazing too. Get that nice raspy/metallic sound with the x-pipe. Received several compliments on it already. If you're on the fence, take the plunge. You won't regret it!
