Product FAQ:
What models do you offer? What's the difference?
We currently offer two great mufflers:
The Paradox "Signature Series", which offers aggressive, high quality sound with revolutionary, patented drone-controlling technology.
Paradox Signature Series Performance Mufflers are great for...
- Modern and classic trucks and cars.
- Pro Street (less than 600 HP).
- Most V8s, V6s, V10s, and 4 cylinder engines.
- A somewhat less loud but just as throaty sounding alternative to Paradox Hot Tamales.
The Paradox "Hot Tamale", which has an even louder (but still refined) sound. The tone quality is similar to the Paradox Signature Series, but somewhat less smooth and somewhat more sharp. This makes it well suited to V8s, and is well suited to being paired with resonators.
Paradox Hot Tamales are great for...
- Stock V8 trucks.
- Modern V8 muscle cars.
- Race and off road.
- Mild vehicles that need a big sound boost.
- Vehicles that aren't loud enough with other performance mufflers.
- Naturally quiet vehicles (such as vehicles with many quiet catalytic converters, e.g. late 90s and 2000s F150s).
- Any situation where you want the loudness a straight pipe, but want higher sound quality than a straight pipe.
What size do I need?
If you're in doubt about what size muffler you need for your vehicle, please feel free to contact our exhaust experts.
In general, we recommend 3.00" for almost all 1/2 ton trucks of any engine (eg. RAM 1500, Ford F150, Titan, etc).
Most V8 cars from the past couple decades use 2.50".
Most 6-cylinder cars are 2.25". Some high performance turbo 6 cylinder cars use 2.50".
4 cylinder cars are typically 2.25" but sometimes smaller.
Will Paradox Performance Mufflers Work On My Vehicle?
Our universal mufflers fit virtually any vehicle with 3.00" diameter pipe or smaller if installed by a professional muffler shop or fabricator.
We designed our mufflers to perform excellently on:
- Most stock/unmodified vehicles of all engine types.
- Most modified V8s up to 600 horsepower.
Without additional sound control, our current models may not be enough for:
- Engines producing 600+ horsepower.
- Supercharged vehicles.
- Heavily tuned/modified 4 and 6 cylinders.
This does not mean they will not work; it simply means you may also need resonators or other means of controlling volume. Headers, aftermarket catalytic converters, tuning, and more can complicate the ability to predict sound.

Why don't you offer more direct-fit kits?
We have chosen to focus our efforts on versatile, high quality universal mufflers rather than kits for specific vehicles. We are a small family business, and we have decided to prioritize excellent customer service and tech support. If you need help with installation on your vehicle, email us by clicking here, or call 417-929-1824.
Can your muffler necks be clamped/welded?
We recommend welding the inlets/outlets. Because of our ultra-thick and ultra heavy duty inlets/outlets, traditional U-bolt exhaust clamps will NOT work.
How to clamp if welding is not an option:
Our mufflers can be clamped with wide "band" (AKA "lap joint") exhaust clamps IF they are installed in a very specific way. The clamps must be at least 3 inches wide. Narrower clamps will not work. You must apply liberal amounts of muffler cement (available at parts stores) inside the inlet and outlet. In addition, you must either put a tack weld on top of the outside of the inlet and outlet before you put the clamp on, OR screw a small screw on top of the inlet and another on the outlet. Doing either of those things will give the clamps something to grip on to so they do not move and loosen.
Are Paradox Performance Mufflers Directional?
Yes. Each muffler has an inlet marking. There is also an etching on the case indicating the flow direction ("FLOW >>>")
How loud/quiet are Paradox Performance Mufflers?
Our Signature Series mufflers are moderately loud, and our Hot Tamale mufflers are extra loud. But keep in mind that mufflers are not the only thing that contributes to sound. Resonators, catalytic converters, headers, engine mods, and more contribute to overall volume and tone quality. Please see the chart below:
Where in the USA are Paradox Performance Mufflers manufactured?
