replace the filter on the k and n cai with an afe pro dry s filter, and get the muffler of your choice. for sound, go with something baffled, like a flowmaster(thats what i love), or something straight thru for performance....like dynomax or magnaflow
. you can also straight pipe the 2 rear cats for a bit more flow/sound. then again, full exhaust(headers back) will add to your power and mileage, as well as a maf calibrator from urd
(expensive, but a definite improvement,from what i hear.) hope this helps.
