Easy to install

It really sounds good and was really easy to install once I have the old exhaust off.

Great Upgrade!!

Added this AfE cat-back and was amazed how easy it was to install.. Once I got my old pipe and muffler off it took about 20 min to finish the project. Total time about an hour. The 3" pipe really makes it sound nice it has a deep tone with very little to no resonating sound that other systems have. There is an increase in HP with this unit. How much I'm not sure but it's noticeable. I also have CAI so putting the two together made a noticeable improvement..

Why is there a 2.5" and a 3" system by afe? Is one better than the other?

Asked by kyle from on

Hello Kyle! The smaller 2.5 inch exhaust is designed to have a smaller profile, thus giving more ground clearance. The 3 inch exhaust produces a bit of a throatier exhaust tone. It comes do to personal preference. If you are doing a lot of off-roading, I'd recommend the 2.5 inch for better clearance. If you are driving mostly on the street, then the 3 inch exhaust is for you!
