XL Series Diesel Exhaust System by MagnaFlow®. These mid-level exhaust systems feature 100% stainless steel satin finish mufflers and mandrel-bent stainless steel tubing with mirror polish clamp-on single wall tips.

Fitment of a MagnaFlow diesel exhaust system improves performance by providing better exhaust scavenging and a better gas flow through the exhaust pipes and muffler(s).

The stainless steel pipes in a MagnaFlow System are mandrel bent, keeping their cross section area through the bends to avoid obstructions to the gas flow. The MagnaFlow System improves exhaust scavenging, which ups horsepower and torque.

The gases are led into the free-flow mufflers with smooth necks and a straight-through, perforated stainless steel tuning pipe. The pipe is wrapped in a stainless mesh wrap and surrounded by tightly packed acoustical fiber in a lap-joint welded stainless steel body. The muffler is finely tuned to dampen irritating pitch notes and to deliver that smooth, deep and powerful tone that is so characteristic of MagnaFlow exhausts. The quality materials and the tight packing of the acoustical material ensure long life and no sound degradation over time.

The careful free-flow design, the first class workmanship and the attention to detail in both design and fabrication combine to achieve the power increase, the finely tuned sound and the long life of MagnaFlow products.

Get your MagnaFlow system now. It is an excellent base for further refinement of your vehicle. And while you are thinking about the next step you can listen to the wonderful music played by your MagnaFlow.

MagnaFlow® has been in business for more than 30 years, with its slogan “Quality – Power – Sound” leading the company on its steady path to success. MagnaFlow is the market leader in exhaust systems. No other brand has managed to fulfill the demands auto enthusiasts have on their exhaust systems, while still complying with emission standards, as MagnaFlow has. The product line is steadily expanding, introducing new, cutting edge technologies and designs. MagnaFlow is the leader in exhaust system design and the company is determined to stay in the lead.

Easy Installation!
I was looking for some system that will give my vehicle something between crazy sound and moderate one. And I’ve made an excellent choice! The installation is easy. The product was everything that I’ve expected. Good deal!
