Product Details

The Borla 40349 ProXS muffler delivers maximum exhaust flow and performance through its straight-through design. Unlike traditional chambered mufflers, this universal performance muffler eliminates restrictive baffles and chambers that impede exhaust gases, resulting in improved horsepower and torque.

Key Features:

  • Straight-through perforated core design for maximum flow efficiency
  • Reversible installation - can be mounted in either direction
  • Center inlet with offset outlet configuration (also works as offset-in/center-out)
  • Un-notched neck design for compatibility with standard exhaust pipe connections
  • Constructed from premium T-304 stainless steel for durability and corrosion resistance
  • Ideal for custom exhaust builds and performance applications

Borla ProXS mufflers (formerly known as Borla Turbo mufflers) are engineered for enthusiasts who demand superior flow characteristics without sacrificing build quality. The straight-through design ensures minimal backpressure while providing a deep, aggressive exhaust note. Perfect for automotive, truck, and marine exhaust systems.

N/A

Found this store thru a google search. Had good reviews so I went for it. Liked that they have google checkout. Email notification was great, tracking number was there. Last but not least they had the best price for my Airaid intake tube.

Recently placed an order for some head studs for my car. They were much less expensive at autoplicity than elsewhere. I was surprised I hadn't heard anything back after a couple days, but was reassured that orders are processed within 24 business hours (3 days), not 24 hours (which I misread in my confirmation email). Just received a shipping confirmation with a tracking number today.

Very easy to navigate website. I recived my order quick and it was also the cheapest online.

I have had a very good experience with Autoplicity and will look for more parts here. I called Customer Service and they were very good and accurate with me. It was easy, they were very nice, immediate response, and great price.
