There are many performance exhaust system manufacturers that make extravagant power claims, with a lot of talk about increased flow with huge exhaust tubing. But their systems usually make the most power at 5000-6000 rpm, an rpm range seldom used on the street, even by performance vehicles. And those sewer pipe sized tubes actually reduce torque at lower rpm, where you need it the most.

The Gibson Split Rear Cat-Back Exhaust System is designed and built to make horsepower and torque for real world driving conditions. Dyno results show that this system makes maximum horsepower and torque at 1800-3000 rpm, where you can feel it during every day driving and where you need it when doing things like towing a trailer. And along with that increased power and improved performance you get better fuel economy, an aggressive, throaty exhaust tone, and a lot of style from 2 separate exhaust pipes and 2 polished exhaust tips that exit straight out the back like dual exhaust.

Gibson designed this exhaust system at their fully equipped research and development center, using engine and chassis dynos, flow benches and audio testing equipment. To make useable real world power, Gibson equips this system with the Superflow muffler and mandrel bent tubing. The all-welded construction Superflow muffler is baffled and chambered for better volume efficiency with unrestricted flow. It’s so efficient it has only 5% exhaust flow restriction, as opposed to the 34% or more restriction in a typical stock muffler, and the 10-20% restriction that exists with some aftermarket mufflers. And the increased flow and great sound is achieved without using any muffler packing, so there’s no packing to blow out. Your exhaust flow and sound will remain consistent throughout the life of the muffler.

The other key to less restriction and improved flow is mandrel bent tubing. First Gibson selects the optimal tubing diameter for the best engine efficiency, not the most exhaust flow, then they use CNC mandrel tube benders to make every tubing bend. Mandrel bending ensures smooth bends and makes sure the pipe maintains its size and shape throughout the entire length. Tubes that aren’t mandrel bent can lose a percentage of their diameter in sharp bends, creating restriction. CNC mandrel bending provides consistent bending so every system flows as designed.

Finally, all Gibson exhaust system components are joined with a “slip fit”, where an exhaust system component fits into the larger opening of the next downstream component. This method reduces the turbulence that is common with ‘ball-and-socket” or “flange-and-gasket” joints, which can cause power-robbing backpressure.

The Gibson Split Rear Cat-Back Exhaust System is available in your choice of stainless steel or aluminized steel. Each comes with highly polished dual T304 stainless steel clampless exhaust tips. The system comes with everything required for installation, including zinc plated factory style hangers and clamps, and detailed instructions. Aluminized systems are warranted against defects in materials and workmanship, but not rust through, for as long as the original purchaser owns the vehicle on which the system is installed. Stainless steel systems are warranted against defects in materials and workmanship, including rust through, for as long as the original purchaser owns the vehicle on which the system is installed.

Gibson exhaust systems are manufactured in the USA.

Great Exhaust System
This is my 3rd purchase of this catback system. High quality and good sound. Easy installation with all hardware provided and exhaust tips. I installed this brand on all my vehicles.

Not an Exact Fit. Could Be Louder.
Supplied clamps would not hold pipes from turning, making installation for one person very difficult. Hanger behind muffler was too long. Ended up buying different hanger and additional clamps to hold pipes from turning. Tail pipes didn't have enough bend to come exactly straight out the back. Expected it to be a little louder but does sound good. Had to remove spare tire and leave off.

Gibson 67402 Stainless
Easy install ~2 hours. Aside from moving a hanger point on one section I love this exhaust kit. Sounds amazing on my 2009 Tundra 4.7, I can even get it to crackle and pop playing around with sport shift mode. Definitely worth the extra money instead of letting some random shop make a trampoline pole exhaust with a Flowmaster muffler. 10/10.

Great System!
The exhaust has a great look to it, and a great sound! If you’re looking for that loud bass sound. This is it! Great pickup for those who don’t want to spend close to a thousand dollars on essentially just a more popular brand. Love it!

Nice System, Disappointing Sound
I ordered this system because it was the only one I found that offered a rear split exit. The description said it had a loud/ aggressive sound that I was looking for. The install went well, nice easy instructions to follow. But when I started the truck, the sound was not even close to what the description said. It did give it a deeper tone, but I'm disappointed in the sound overall. As far the exhaust system itself, it is really well made, easy to install, and looks good. This went on a 2001 Ford F250 V10.

Catback for My Tahoe
It looks great and sounds awesome. Not much of a problem to install but did have problems with aligning up the tips with the short pipe there was a 2 inch difference in the alignment. A special pipe had to be bent in order for the tips to exit outside the rear bumper. The system is a well thought-out kit and I am happy with it.

Incredible new deep/quiet sound!!
I love it! That was the first three words that came out of our customer’s mouth, then he said that it looks very clean and professional, he said that his truck never had that smooth sound since the day he bought it!

Gibson Exhaust
Exhaust looks great on, definite increase in hp, install was very simple and didn't take long, cutting old muffler off save time and effort, would recommend by far over the other overpriced exhaust systems, just paying for the name.
