I just picked up a 2001 f150 super crew cab 4x4 5.4 for 800 needs a key is all fyi that back door just needs the cable replaced my ole 99 I had did that and I rigged it up to a pull string and it worked great after words
I had a couple of exhausts on mine it was a 4.6 first was straight piped it was way obnoxious Second was a six inch cherry bomb from autozone it sounded perfect And the last one was a flowmaster 40 it sounded decent but the cherry bomb was hands down the best it gave it a hotrod sound for the price
