Moroso 2.5" Racing Muffler

Model Number: 601903

Moroso Spiral Flow Mufflers available in 2.5 inch inlet, and 3 inch inlet. Modern Performance has chosen to carry this product because of its small diameter sizing, and great efficiency at reducing noise levels. Because of its size, it can be installed in the exhaust tunnels, and other small areas where space is limited.

Using advanced gas dynamics and sophisticated noise cancellation acoustics, Moroso engineers have developed a new series of Racing Mufflers. Specially engineered spiral baffles divide the exhaust flow into two separate paths, significantly reducing noise levels with minimal backpressure. The all-steel construction makes them durable, our efficient manufacturing process makes them affordable!

This is a special order item which can take 1-2 weeks.

      This is NOT for use on a turbo car, please use the straight through resonator, or ultra quiet resonator instead.

      You should first measure your exhaust piping to make sure this is the right size. If your exhaust piping is 2.25 inch, then this will work great. After purchasing this from us, take your car to a muffler shop, and they will cut your exhaust piping, and weld this on.

    Why do you say "this is NOT for use on a turbo car" in a response to another question? I assume because it's not a straight though design and the less back-pressure on a turbo car the better?

      This muffler was designed for non turbo use by Moroso. They have specifically told us that. In almost all instances, when you have a turbo car, you need straight though designs with packing around the piping, due to the extreme heat and velocity.

    I live above the salt belt and am worried about this muffler rotting. Is this made of stainless steel or should I get it coated/go a different route?

      You should either a) Look for a stainless muffler for your car or b) if you use this, give it a respray of paint periodically to help protect it.
