The Tone You've Been Looking For

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” does.

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.

    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.

    These signature series mufflers got rid of the drone my previous ones had. Made driving my car enjoyable while having a nice overall sound.

    Still loving my mufflers! I get compliments on them all the time. I tell them whose muffler I am running! It still has barely to non-existent drone while cruising.
