Seriously Ihave a 4 banger with 33"s also.
Get your self a flowmaster muffler. Good deep sound and not bothersome loud. You will notice imediate performance increse.
Get K&N filter and air-tube system - you will see slight increase here too.</strong></font><hr /></blockquote><font size="2" face="Verdana, Arial">I'm going to say BS on that. You will not notice a difference except sound. All an exhaust will increase is 2-5 horse power. Like adding a lawn mower engine to your Jeep. You can't tell that little of a change. There is nothing you can do without completely starting over. 4 bangers are not meant for power.
