I've got one just like it. Mine is also a 07 Limited v8 and 4x4. I've changed out the exhaust, headers and air intake. All three helped with sound, fuel economy and the nagging question "they v8s in those". Only other thing i did was put on cut outs on the exhaust at the end of the headers...
Would anyone be interested in doing a meetup of fellow Sportrac owners in North Georgia? Do a meet up say at Home Depot parking lot in Jasper,GA. I’ve recently got interested in trying to do one and was wondering if anyone else would be interested in doing one. Let me know if you would.
I had the muffler and resonator cut off of mine. I went back with a Flowmaster series 40 muffler. It's not overly loud but great sound. My sportrac is an 07 with 4.6.
I know from trying to find one almost 4 years ago in the same configuration,God luck. Wont br cheap but worth it. I like mine. Wish Ford would bring it back.
