Wish I bought it 3 years ago

Very simple for the mech to install. In fact, it was harder and took 3 times longer to remove the original. Noticed the awesome rumbling sound of those engine gases being expelled through the mandrel-bent pipes as soon as that ignition was turned on. The vehicle instant-power increase was also immediately obvious from the first drive out of the workshop. Fuel usage decreased by over 0.5 litres per 100km, in on-road congested traffic conditions. So, given the vehicle is not only a play-weapon, but also a daily driver...this exhaust will actually pay for itself in fuel-cost savings, in about 18 months. Additionally, by replacing the stock exhaust, the muffler is removed from the vulnerable position at the rear of the vehicle...this was an added advantage as this then allowed the interior cargo 'tray'-slot 'bay' to be cut out and an enlarged custom interior storage 2nd battery tray to be installed. Impossible with the OEM muffler in location. A great, quality product and well worthwhile dollar value. Highly recommended.

Ok so I'm interested in this product but I have a quick question... I drive a fully stock 2011 Wrangler Sport Unlimited and I'm wondering how easy, if I even have to, relocate the evap canister? I like the fact that I can create more space where the stock muffler is, as well as make the jeep sound a little better, but I'm no mechanic so I don't know what an Evap canister is or even how to relocate it. Any little bit helps, thanks!

Asked by SomeGuy from Lycoming, PA on

Hi there! When you install this cat-back exhaust system you will need to relocate the evap canister, or the exhaust will hit it. The evap canister is on a vehicle is used to recirculate the air from the gas tank. All the gasoline vapor is absorbed by the charcoal material in the canister, so you aren't smelling gas all the time. We also sell the relocation brackets for the canister, Rock Hard 4x4 part# RFPRH6005-A
