I have a 2002 6cyl 5 spd manual TJ which is stock. I'm interested in dropping some dollars on it to improve performance somewhat and maybe increase mpg somewhat.
It has been recommended to me that I go the Borla header and cat back route. I'm wondering, however, if these mods will really accomplish much of anything on a 2002 TJ. I suspect that the stock exhaust is fine and the aftermarket stuff is really unnecessary.
I'm therefore interested in opinons as to whether money spent for headers and cat back will be money well spent on a 2002 TJ -- or just wasted. By the way, I don't care at all about increased "cool noises" out of the Borla deal as I think the TJ is loud enough overall as is! It's performance and mpg that I'm interested in. Thanks!
