Borla Touring Cat-Back Exhaust System for 2003 Ford Thunderbird 3.9L V8 Automatic Transmission Rear Wheel Drive; 2 Door Coupe; Convertible. (140081)

Upgrading your factory exhaust system to a Borla stainless steel performance exhaust system with a more efficient and less restrictive design can improve sound (adding more enjoyment driving your vehicle) and increase engine horsepower and torque throughout the RPM range (allowing quicker acceleration to pass a vehicle or get to highway speeds quicker). Borla offers Axle Back exhaust systems, Cat back exhaust systems, and for select Competition-Use-Only vehicles, we offer long tube headers to replace your exhaust manifold for the best performance and sound.

The Borla "Cat Back™" name implies the exhaust system is located behind the factory catalytic converter where there factory emissions remain untouched and vehicle stays emissions compliant. This remains distinct from the Axle Back exhaust system that is located behind the rear axle. Alex Borla coined the phrase 'Cat Back' and introduced the Cat Back performance exhaust in 1978, a bolt-on replacement performance exhaust system requiring no welding, thus being secured using the factory hanger locations.

Borla Cat Back exhaust systems use engine-specific (not universal) mufflers that are designed, tested, and optimized specifically for a particular year/make/model vehicle. Borla Cat Back systems increase the overall sound level & performance. Vehicles that don't have a factory service-point require "cutting" the factory exhaust system before installing a Borla Cat Back performance exhaust system. Borla includes instructions where to make this cut and includes the hardware to complete the installation. Many of today's modern vehicles have a factory service-point in the exhaust system (flange or slip-fit) located in the exhaust tubing behind the catalytic converter. A Borla Cat Back performance exhaust system replaces the factory exhaust system (behind this service-point) following the same exhaust path and secured using the original vehicle hangars and rubber isolators. Borla pioneered the automotive exhaust aftermarket in exhausts constructed in aircraft grade 304 stainless steel tubing, a material with higher content of carbon & nickel that won't rust or corrode.

Features:

  • Horsepower and Torque Increased by 7 – 10%
  • Increased exhaust flow for better performance
  • Better fuel economy at cruising speeds
  • The most aggressive sound of any Borla system
  • Custom designed for each application
  • Patented straight-through, multi-core muffler design reduces backpressure while absorbing sound waves
  • Mandrel-bent stainless steel tubes with diameters optimized for reduced restriction while maintaining exhaust gas speed
  • Made from the finest austenitic stainless steel for long-lasting durability
  • All welded construction
  • Includes everything required for installation, including detailed instructions
  • Backed by the exclusive Borla Million-Mile warranty
  • Proudly made in the USA more

BORLA Cat-Back and Axle-Back exhaust systems feature patented straight-through and multi-core technology designed to unleash hidden horsepower. Increased exhaust velocity adds power, driving excitement, fuel economy, and the distinctive BORLA Sound of Power respected by motoring enthusiasts everywhere.

Simple, Reliable, and Works Great
Size: 1 Pack, Style: USB Receiver, Color: Swift Grey
The Logitech M185 has been exactly what I needed for everyday computer use. Setup took less than a minute—just plug in the tiny USB receiver and it was ready to go. The mouse responds smoothly, tracks accurately, and feels comfortable in my hand even after several hours of use. What I appreciate most is the reliability. The wireless connection has been stable with no noticeable lag or dropouts, and the battery life has been excellent. For browsing, office work, and general daily tasks, this mouse delivers solid performance at a very reasonable price. I'm extremely happy with it.

Basic mouse that works - - for now.
Size: 1 Pack, Style: USB Receiver, Color: Blue
I ordered this mouse (in blue) to replace the recently deceased exact same model that I've used for the past 2 or 3 years. I like the simplicity of the M185 mouse and mostly the best bang for your buck! I caught this one on sale for less than a ten-spot, so I thought, "why not." I'm hoping that this one will last a bit longer than my two previous M185 models, that averaged about 3 years each. This model seems plagued by a short life span and is predisposed to mysteriously and suddenly dying, without any obvious symptoms or warning of any kind - - you're working and clicking along, going about your day, when suddenly the cursor on the computer screen freezes and that's it. Nothing, zero, nada. Funny thing, I'm very careful not to abuse or drop the mouse, and keep a fresh battery installed and watch for leakage and all that stuff - - they just stop working, and I assume it is caused by some sort of inherent electronic fault in the circuitry of the previous M185's. Due to my loyalty to the brand and model (and since it was on sale) I decided to give it one more shot. They say that "third time's a charm". I like the fact that the M185 is simple and uncluttered with extra buttons that I would never use for my purpose, which is simple web-browsing and the occasional text document production. The feel is solid, not heavy, but not cheap feeling, either. I'm used to the shape of this mouse, which to me is quite comfortable for long sessions, another reason why I kind of wanted to stay with this model. The buttons have an audible "click", which doesn't bother me at all, and the wheel moves smoothly and also has a clicking operation (which I rarely ever use). The overall surface of the mouse has a matte finish, but like my previous models I'm sure it will eventually wear shiny spots where my fingers reside and will attain a more "well-used" look in time. Connecting it was a breeze, too. I just plugged the dongle into a spare rear usb port of my desktop, and the mouse connected instantly, no problem. The dongle can be stored safely inside the battery compartment, so you can take the whole thing out of the house if needed for use elsewhere. The speed of 1000 dpi seems just right for my purposes. The one I ordered even came with its own AA Duracell battery, which I wasn't really expecting. This mouse also enters "sleep mode" when you don't use it for a while, and I can't say how many times I've got up and left it on all night. And that's not hard to do, as I'll explain next. The only real negative to this mouse is the absence of any easily visible status indicator of it's on / off switch. The rear housing of this mouse is matte black, including the tiny switch where you turn it on and off with your fingernail, with only a very faint "on" lettering (also black), and very hard to see with my aging eyes. The laser is not lighted or visible when on, also adding to the confusion, especially in a darkened room. So, as a workaround, I took a tiny drop of green paint and placed it down inside the switch slider to visibly help indicate the "on" position, and likewise a dot of bright orange for the "off" position. Many of Logitech's more expensive models (and a few other manufacturers) include this color-coded switch indication. I guess for the $$, they had to cut corners somewhere - - a minor complaint. In summary, this is a good basic mouse that works - - let's hope that this one will last longer than its two predecessors.

Dependable, Reliable
Size: 1 Pack, Style: USB Receiver, Color: Swift Grey, Size: 1 Pack, Style: USB Receiver, Color: Swift Grey
As advertised. Logitech, best mouse for your hard-earned cheddar! It’s not that the (years) old Logitech mouse failed in any operational way, it just got that gummy, sticky surface texture that’s impossible to remove. While shopping for a replacement I noticed an off-brand mouse/keyboard combo and thought, “hey, 2 for 1”…mistake. All was well for about three weeks, long enough that when the gremlins arrived I didn’t immediately associate the new hardware. For the purposes of this discussion, gentle reader, know that I run legacy (what I affectionately refer to as, “Lazarus”) builds. Rigs that started life running Windows Vista/7, died, and that now, resurrected, run 10 and 11, and all that that implies. So, when a mouse started stuttering, of course I thought it was a gremlin in the machine, right? I spent more days than I am comfortable sharing with you pouring over processes and background apps, and registry trims…before Accam’s Razor suggested I eliminate the mouse as a variable. Changing the battery was ineffective, but when I swapped in the ooold Logitech…Yahtzee/Bingo/Booyah…smooth and precise…butter! All I needed was a new Logitech mouse. So, if you’re here you likely are having mouse issues of your own, or you just need one that works…this is it! 😉
