honestly i believe the truck ran better better with the stock one on.QUOTE]
Wow. No offense, but you're not exactly a salesman are you?
I'll give you a bump. I like the system. There's NO WAY it causes a drop in performance, but it's not going to make you do laps around a stock 4runner. The benefits are a clean look, durability, quality sound (a healthy, civil rumble. It's not going to wake the neighbors), affordable in comparison to other systems, and easy installation (harder to get the stock system off than the Gibson on).
Buy this if you want it for sound and appearance, not if you want to shave 5/10th's of a second off your 0 - 60 time. Remember, it's a 4runner not a Mustang.
