I have an EJ22E and was wondering if there was anything I could do for less than a small fortune to up the HP output. Not really looking to force induction, as that is a ROYAL PITA on an NA. Just maybe upgrading parts here and there to get a few more HP. I already need/want a new exhaust system (2-inch pipe w/UEL and mild muffler)
Any and all advice is much appreciated!
