Alright, let’s talk about the Borla ProXS Muffler. If you’re looking to amp up your exhaust game without going overboard, this is the real deal. It’s got a single inlet and dual outlets, which means you can set it up in a way that works best for your ride. Whether you're running a system with a single inlet and dual outlets or you want to flip it to fit dual inlets with a single outlet, this muffler is versatile enough to handle it.

One of the standout features is the T-304 stainless steel construction. This stuff is tough and won’t rust on you, which is a huge plus if you live in a place where the roads get salty in winter. The 100% welded construction adds to its durability, so you know it can take a beating. Plus, the free-flow design helps improve exhaust flow, which can give your engine a little boost in performance. And let’s be real, who doesn’t want that?

Sound is a big deal when it comes to exhaust systems, and Borla has you covered here too. They use high-temperature continuous-filament fiber (CFF) acoustic material to keep things sounding just right. You get that deep, throaty roar without the annoying drone that can drive you crazy on long drives. The natural mill finish looks good as is, but if you’re feeling fancy, you can brush or polish it up before installing.

Now, for the specs: this muffler measures 4 inches high, 9.5 inches wide, and 19 inches long. The inlet connection is a 3-inch pipe with a center position, and the dual rear outlets are 2.25 inches each. The overall length comes in at 24 inches, and it’s shaped like an oval, which helps with fitment in tighter spaces.

And here’s the kicker: it’s made in the USA and comes with Borla’s Million-Mile warranty. That’s a testament to their confidence in their product. If you’re serious about your exhaust setup, you can’t go wrong with this one.

Note all attachment to universal mufflers must be made at the nipples; there should be no welding to the shell or end caps as this will void the warranty.

If you have any problems with a BORLA® product, involving either installation or performance, please call the company you bought it from immediately. BORLA® Distributors will take all necessary steps to ensure you are satisfied.

Because sound is subjective, we do not warranty for sound. Please do not return your BORLA® product if you do not like the sound level. There are several ways to adjust the sound level. You can obtain venturies, for example, from your retailer that you can place in your system to quiet your system.

If you must return part or all of your purchase to your retailer, call first.
