Backpressure normal on stock exhaust?
2004 TJ Sport, 242ci I6, 5sp man... The RPM drop after a rev is a little slow for my liking. I would think that the quicker it is able to drop back to idle would be better. I feel like I'm not getting as much power to the wheels or trans b/c of the back-pressure. I'm not a mechanic, that's why I'm asking. Am I right? Do most people upgrade the exhaust, or is it something that most of the time is overlooked?
