i beg to differ. 07 4.0 xlt i put JBA headers on it, and mid range is way more noticeable! well worth the money in my opinion!
i need to fix my exhaust leak tho b/c i lost some of the bolts :( ha so the drivers side is missing 2 bolts on top next to each other and 1 on the bottom. i stripped out the hole in the head so i have to buy a tap and re-thread it.
PIA to install.. but i also did it with crap for tools. like 6 3" extensions and 1 swivle ha. they dont affect the sound to much thru a stock muffler.
well worth the money in my opinion. ill load some pictures of the JBA's compared to factory sunday.
