Product Information

MSRP: $950.00
Average Price: $1,639,344,644.77
Manufacturer: Borla
Yes: 76 / No: 2

Exhaust systems have a tough life. Outside, they face salt, mud, water, crud, and rocks, among other road hazards! Internally, they experience unburned hydrocarbons, acids, and moisture. All Borla systems feature tough 16-Gauge T-304 Stainless steel construction. It's so tough that Borla backs each system with A Million-Mile Warranty.
Cat Back Systems run from the rear of the catalytic converter to the end of your vehicle. Adds throaty sound characteristics, and provides mild performance gains with tuned exhaust flow.

Price: $600.00
Pros: Great sound
Cons: None
Recommended? Yes

Comments: Personally, I think Borla exhaust systems sound the best. The sound is deep without any rasp or "hollowness" and is very smooth. It's not the loudest exhaust on the market which makes it more "sophisticated" than annoying. The sound is proportional to the throttle input (doesn't sound like you're trying to go all-out when you're just easing away from a stop. Revving the engine gives a satisfying burble as the revs drop. There's no drone at speed. The construction and materials are top-notch.

Price: $362.00
Pros: Stainless! Two pieces with all the parts to install Two different exhaust tips (fancy-onroad and turndown for offroad) Warranty Price (I got mine through Amazon for $362 bucks) Sound! No drone
Cons: none --- yet
Recommended? Yes

Comments: I wanted to upgrade from the stock exhaust on my 2004 LJ. I was researching two brands, Magnaflow and Borla. I heard both on a 4.0 Jeep at a local 4WD Parts store and got price quotes. Both were in low to mid $400 range. Install was extra.

Decided to look online and do it myself. Amazon has the cat-back system for $362 and with Prime....2 day free shipping.

Received in a pristine box! Two pieces and a super easy install! Biggest PITA was the skid plate reinstallation by myself. Everything went perfect, did not even need instructions.

It sounds great, throaty but not obnoxious. It even came with two exhaust tips, one for onroad that looks great and one for offroad.

I have had in on the Jeep for a month and love it. I have even noticed a slight performance advantage on the highway and mild gas mileage improvements. Nothing to brag about though, but I will take any that I can get!

I would recommend this product to all 4.0 Jeep owners, you will not be disappointed!

Pros: Great sound & performance.
Cons: None
Recommended? Yes

Comments: I have had my Borla Cat-Back exhaust system on my '91 YJ for about 12 years. It still sounds great and there are no leaks. It's not pretty to look at anymore but its easy to remove and reinstall if you ever need to. The exhaust tip gets a little bent up from hitting/dragging across rocks & logs (bent but not broken).

Pros: great tone on deceleration, easy install
Cons: none so far
Recommended? Yes

Comments: this exhaust system has met all of my expectations.. ease of installation and nice appearance at the tip. The sound is what I was looking for, a nice rumble at low soeeds with a real nice low pitched rumble on the down shift. At highway speeds the sound is not overwhelming. I installed a Smittybuily rear bumper and had to use a longer rear exhaust hanger and grind out a notch ao the exhaust tip for clearance.

Comments: I installed this system in 2002 and it has helped with performance and fuel economy. It sounds great with the 4.0L. I have slammed it on many stumps and rocks and it is still holding up. Did I mention that it sounds great with the 4.0L?

Price: $175.00
Pros: High Flow Good sound (not over the top) Solid construction cooler running exhaust
Cons: none
Recommended? Yes

Comments: It is not actually a "cat-back" system, but the Borla Pro2 muffler. The cost included installation.
I got this because I have a turbo charger and as a JF member once wrote:
"There's no point in taking a big breath of air if you're going to exhale through a straw."
After the installation, my Turbo Charger performance increased by 2 psi and the engine response upgrade was significant.
The sound is a nice tone that lets other drivers know you've got something, without shouting it, and there is little in-cabin resonance.
I always ditch factory mufflers as soon as I can afford to, regardless of intake modifications; and always see performance and usually MPG gains.
