Paradox Performance Mufflers bring out the personality of your vehicle. Our patented Tuning Fork Technology delivers deep, complex tones that other brands can't match.

Revolutionary, Drone Eliminating Technology

What if your muffler was loud when you wanted it to be, and quieter when you didn't want it to be?

That’s exactly what our patented “Tuning Fork Technology” can do.

Our mufflers provide a bold, deep tone when idling and under acceleration. But at highway speeds, Paradox Performance Mufflers become quieter, which can reduce or even eliminate exhaust drone.

This is why Paradox Performance Mufflers are unlike any other muffler on the planet, and it's also why they provide unmatched sound and flow.

    1976 Ford Torino, 351 Windsor

    Posted by Dale S.

    After reading several positive reviews online, we decided to install two (USA-built) Paradox Signature Series mufflers on my son's 351-W equipped 1976 Ford Torino. The car is factory original but now has dual exhaust. Shipping was quick and Andy and his dad were super helpful in answering all of our application questions. On the ride home from the muffler shop, especially at stop lights, quite a few people gave their "thumbs-up" approval of the new sound. The car has a nice low rumble at idle and will growl when you want it to. A lot of muffler companies make that claim, but many have an annoying interior drone at highway speeds to go along with it. This is not the case with the Paradox mufflers. Their unique design keeps the highway cruising sound effectively drone-free. In summary, the look of pride on my son's face every time he fires up his ride makes this one of our most rewarding purchases to date!

    Absolutely no drone. You can barely tell it's on there until you press the pedal down. I wasn't sure how a 6 cylinder was going to sound but the paradox original was definitely worth the investment. As a side note it changed the shift pattern on the 8 speed auto…. for the better. It also woke me up to the fact that I am too old for a warranty… so the next step is a tune.

    Great muffler

    These mufflers have taken my Audi A7 to the next level, great sound and look awesome with my after market exhaust tips. Nothing but compliments on the sound of my car. And no drone. Thanks

    5/5 unique tone! - 2012 Titan 5.6

    Posted by Dylan Collins

    I got to looking for something different, not a flowmaster, magnaflow, borla, etc and I'm so glad I came across you guys. What I ended up with was 2.25 duals to a 3 inch Y pipe and signature series muffler that kept the factory routing with 3 inch pipe. The sound is done no justice by phone camera, keeps a nice burly tone throughout the RPMs but is very tame cruising down the highway. Service was straightforward and the muffler quality is top notch!

    The nicest sounding muffler you can find for the 3.8 L engine. Nice low tone and no rasp at all.
