Jones Turbine JT2540i Rear Mount Mufflers are a packless, full 304 stainless steel high performance exhaust muffler with an integrated 4" tip. Utilize this stainless steel muffler on any 2.5" exhaust system to Utilize the Jones Turbine's ability to reduce your vehicles exhaust gas temperatures (EGT's), as well as increase its power, torque, and fuel economy, while reducing engine wear and tear.

Revolutionary Design

The Jones Turbine is a straight thru design, high performance muffler that features a built in resonator for added sound suppression. Jones Turbine mufflers utilize the principles of thermodynamics to reduce EGT's, increase horsepower, torque, fuel economy, and reduce engine wear and tear. With its fully welded 304 Stainless Steel construction, the Jones Turbine is nearly indestructible. The Jones Turbine is a natural choice for the performance minded enthusiast.

Learn How It Works

As the exhaust stream enters the Jones Turbine muffler, it expands to fill the cylindrical chamber. This expansion slows the exhaust stream, creating a lower pressure at the inlet which causes a scavenging effect similar to that of a header. The exhaust stream is then split and the outer stream accelerates to a higher velocity as it flows around the nose and has a lower pressure than the core stream, which is traveling at a slower velocity, and a higher pressure. The two streams are reintroduced via perforations in the center core. The high pressure inner stream is initially drawn out of these perforations as the gas attempts to equalize the pressure differential between the two streams. As this occurs, the change in direction of the exhaust stream causes destructive interference, which deadens the sound. As the pressure is equalized towards the rear of the canister the exhaust gas is pushed back through the helically arranged perforations in the center core, which spin the exhaust stream, causing additional sound cancellation, reducing turbulence, and creating a vortex that enables the gas to more efficiently exit the muffler. This revolutionary design has been tested and proven to flow more exhaust gas than straight pipe!
