Features
- Classic S-Type sound: Borla puts S-Type in the middle of its three sound levels: bolder than Touring and a little tamer than ATAK. Borla describes it as aggressive when you get on the throttle and more refined once you settle into a cruise.
- Starts behind the converters: A Cat-Back system takes over from the catalytic converters rearward and swaps the pipes, mufflers and tips that follow them. The factory converters are not touched and stay on the vehicle.
- Muffler tuned to the vehicle: Borla develops each system on the vehicle it is sold for, working out the muffler body, core layout and pipe routing around that engine, so the S-Type character suits the platform rather than a generic muffler.
- T-304 stainless steel: Every system in this family is built from T-304 austenitic stainless steel. Borla picks it over 409 and aluminized steel because it stands up far better to road salt, moisture and repeated heat cycles.
- Million-Mile Warranty: Borla covers the system against flaws in materials or workmanship for one million miles, for the original buyer on the vehicle it was first fitted to. Tip finishes, black coatings and carbon fiber carry a one-year term.
- Turn-down Climber exit: This system ends in a turn-down outlet tucked up for trail clearance, so there is no tip at the bumper to catch on rocks or ledges.
Description & Fitment
Borla S-Type cat-back 140644 is listed for the 2012-2015 Jeep Wrangler JK 2-door with the 3.6L V6, automatic or manual. It is a high-clearance Climber system that ends in a turn-down outlet instead of a tip at the bumper. The listing gives stainless steel tubing stepping from 2" to 2.5". Borla places S-Type between its mild Touring and loud ATAK sound levels.

About Borla
Borla got its start in 1978 making stainless exhaust systems for concours Rolls-Royce and Ferrari restorations, and says the term Cat-Back began with it that same year. The company still builds in stainless steel, now at a 100-acre plant in Tennessee, and Borla says automakers including GM, Ford and Toyota use it for some of their factory-installed accessory exhaust.
Borla engineers each vehicle system from a clean sheet, shaping the muffler bodies, cores and pipe routing around that one platform, and offers many of its systems in three sound levels: Touring, S-Type and ATAK. For custom work it makes ProXS universal mufflers, CrateMufflers tuned to crate engines, exhaust tips, tubing, clamps and hangers.

Frequently Asked Questions
Will this fit my 2012-2015 Wrangler 3.6L?
It does when your Jeep is a JK 2-door with the 3.6L V6, automatic or manual. If anything differs, send us your VIN before ordering.
Is the photo this exact system?
No. We do not have a photo of 140644 itself yet, so the image is a representative Borla cat-back. The parts in the box are made for the vehicle in the fitment row; contact us if you want to see the part before ordering.
How does S-Type compare with Touring and ATAK?
Borla ranks its three sound levels with Touring the mildest, ATAK the loudest and S-Type between them. S-Type turns aggressive under throttle and calms to a smoother note at a steady cruise.
Do the catalytic converters stay in place?
Yes. A Cat-Back system begins behind the catalytic converters, so the factory converters stay on the vehicle and only the exhaust after them is replaced.
Do I need a shop to install it?
Borla recommends an exhaust shop or professional installer for these systems and warns against air impact tools. A second person to hold the system up while it is hung helps on many vehicles. Some vehicles need the factory pipe cut; the Installation section on each product says whether yours does.
Can I send it back if I don't like the sound?
Borla does not warrant sound level, because how an exhaust sounds is a personal call, and it asks owners not to return a part for that reason. Settle on the sound level before you order. Borla notes that venturis, available from a retailer, can quiet a system later. For any other return question, contact us before you ship anything back.
Installation
- 3/8" drive ratchet
- Extensions
- 13mm and 15mm sockets and a pry bar
- No air impact tools

Warranty, shipping & returns

Warranty
Borla's Million-Mile Warranty covers this part for one million miles against flaws in its materials or workmanship.- Coverage belongs to the original purchaser of record, on the vehicle the part was first installed on.
- Black coatings, tip finishes, carbon fiber and moving parts such as valves and actuators carry a one-year term. Blemishes or marring caused by weather, road hazards, lack of maintenance or extreme heat or cold are not covered.
- Borla inspects the returned part, and when it finds a manufacturing or material defect it repairs or replaces the part, at Borla's option.
- Sound level is not warranted, since sound is a matter of taste. Borla notes that venturis can be fitted to quiet a system.
- Universal mufflers must be joined at their inlet and outlet necks. Welding to the case shell or end caps voids the warranty.
- Not covered: the cost of removal or reinstallation; damage from accident, abuse, misuse or misapplication; parts that are modified or used for something other than their intended purpose; racing products, and street parts used for racing.
- To claim, contact us first with your order number and a short description of the problem. Borla asks for proof of the retail purchase date, and your Prestige Truck receipt is that proof. A part sent back to Borla travels with freight prepaid by the sender, packed well, since Borla cannot accept parts damaged in transit.
- Some states do not allow these limits, so your rights may vary by state.
