What models do you offer?

We currently offer:

The "Signature Series" which comes in 2 Versions. Both versions have the same sound:

Signature Series Elite: Stainless case, seamless ends, and a limited lifetime warranty.
Signature Series Premium: Aluminized steel case, and a limited 5 year warranty.

The "Hot Tamale", which has a louder (but still refined) sound. The current version of the Hot Tamales have a stainless case and a limited lifetime warranty.

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 extra sound control, our current models may not be enough for:

Engines producing 600+ horsepower.
Supercharged vehicles.
Heavily tuned/ultra modified 4 and 6 cylinders.

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

How loud/quiet are Paradox Performance Mufflers?

Our Signature Series mufflers are moderately loud, and our Hot Tamale mufflers are extra loud. Please see the chart below:

Can the necks be clamped/welded?

We recommend welding the inlets/outlets. Because of our ultra-thick and ultra heavy duty inlets/outlets, traditional 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.
