SpinTech Mufflers & Exhaust

Spintech Performance Mufflers, Cat-back Exhaust, Axle-back Exhaust, Mid-Pipes and More

 

Think of SpinTech as a Saturn Rocket inside Your Exhaust System. It began as a NASA engineering challenge. Design a rocket booster exhaust system with exceptional output power and build it to reduce noise, even as velocities and throttle settings increase. SpinTech engineers did just that. Inspired by this technology, SpinTech has established itself as one of the newest and hottest players in the most competitive racing arenas across the country.

SpinTech's entropy mufflers provide the most effective sound attenuation in the industry without sacrificing performance power. It's all done by means of a patented spin sound trap, which captures sound vibration energy and turns it into heat energy within the muffler. On size, weight and effectiveness comparison, no other type of muffler works as well. Unlike friction mufflers which have high back-pressure, and absorption mufflers (straight thru type) which are loud and get louder as they wear out, SpinTech's sound trap entropy mufflers have flow rates approaching the straight-thru types, no packing to blow out, and the maximum attenuation of any type muffler at high flow velocities.

SpinTech's patented technology is based on the second law of thermodynamics or entropy. The entropy of a system relates to the organization of the system. Sound energy actually represents a form of organized energy in the sense that the molecules of air or gas vibrate together in a unified way. (On a microscopic level these gas molecules bounce off one another like billiard balls). Heat energy is also the vibration of molecules. Heat and sound energy are very much the same except for their organization, or entropy. Heat is a completely randomized molecular vibration, while a sound wave is an organized wave front of vibration.

Flow routing is based on advanced fluid mechanics technology. Vortexes are sustained inside of the muffler's spin sound traps. Vent holes are placed in an area where the case wall and the sound trap form a Venturi effect. As gas flows through the vent holes, the reduced pressure extracts gas out of the trap. Incoming exhaust from the main exhaust flow stream refills the trap and maintains the vortex motion that promotes the conversion of sound to heat. Think of it as a Saturn Rocket Inside Your Exhaust System.

In the early 1980's, mufflers on race cars were rare, but as the population encroached on local race venues, sound levels started being monitored. As sound level regulations became more stringent it was apparent performance was being compromised and the search for performance race mufflers began. In late 1995, SpinTech began to develop a high flow racing muffler for competition. After over a year of testing under real race conditions as well as engine room dyno-testing, SpinTech was ready to go heads up against other performance mufflers. Today, SpinTech is still unmatched in muffler performance. Accesspeed is proud to offer SpinTech products to our customers.

Down-Pipes

 

What is a down-pipe?

A down-pipe is an exhaust tube that directs the exhaust gases from your vehicle's turbo “down” into your exhaust system. The downpipe typically bolts onto the exhaust side of your turbo housing, and connects at your mid-pipe section. Some down-pipe exhaust brands include catalytic converters and others are simply straight-though pipes that bypass and/or eliminate the catalytic converter.

 

Does a down-pipe make your exhaust louder?

Yes. Most aftermarket down pipes have a straight-through design that will reduce backpressure and increase exhaust efficient. This makes your exhaust louder with a more aggressive note.

 

Does a downpipe increase horsepower?

An aftermarket down-pipe on any turbocharged engine should increase horsepower. In most cases, the upgraded down pipe will allow the turbo to spool quicker and hold a higher boost level.

 

Does a downpipe increase fuel economy?

Like most upgrades that reduce backpressure and allow exhaust gasses to exit more efficiently, you can realize a fuel mileage gain. However, most Accesspeed customers are simply unable to keep their foot out of the throttle long enough to see the fuel economy improvement.  

 

Are down-pipes legal or illegal in my state?

If a down pipe requires modification or removal of the OEM catalytic converter, it is likely not legal. If the down-pipe you want to order is not 50-state legal (CARB-approved) with a proper EO#, it is most likely illegal in your state. We recommend checking your state laws to verify prior to purchasing.
