What is the main benefit of a straight-through muffler design?

A straight-through muffler allows exhaust gases to flow directly through the muffler with minimal obstruction. This reduces back-pressure compared to mufflers with internal chambers and baffles, which can improve engine performance and sound.

How does the expansion chamber help?

The exclusive expansion chamber is designed to absorb and dissipate specific sound frequencies that cause mid-range drone. This helps create a more comfortable exhaust note, especially during steady cruising.

What material is the muffler made of and why is that important?

The muffler is constructed from polished stainless steel. This material is chosen for its resistance to rust and corrosion, which helps extend the life of the muffler, especially in harsh weather conditions.

Product Details

You get a polished stainless steel muffler in this Banks Power exhaust muffler. It replaces the restrictive stock muffler on your 2004-2005 Jeep Wrangler 4.0L, making a difference in airflow and sound. The straight-through design means exhaust gases don't have to wind around inside hairpin chambers, which cuts down on back-pressure.

This muffler uses durable ceramic packing that can handle high temperatures without degrading. It also has an exclusive expansion chamber to reduce the mid-range drone that other straight-through mufflers can produce. The result is a pleasing, throaty rumble that's authoritative but not overpowering.
