Prime Race Parts | 4" Titanium Oval Muffler (127 x 203 x 355mm)

Prime Race Parts Titanium Oval Muffler – 4" – 127 x 203 x 355mm

Part Number: 4MUFF

Reduce exhaust noise without adding unnecessary weight with the Prime Race Parts 4" Titanium Oval Muffler.

Designed for high-performance and motorsport exhaust systems, this lightweight titanium muffler combines a compact oval body with a large 4-inch inlet and outlet size, making it well suited to high-flow turbocharged, naturally aspirated and competition exhaust applications.

The oval body measures 127mm x 203mm x 355mm, providing a compact packaging solution for race cars and performance vehicles where underbody, tunnel or rear-section clearance can be limited.

Titanium construction helps significantly reduce exhaust-system weight compared with conventional stainless-steel mufflers, while also providing excellent corrosion resistance and a premium motorsport finish.

Why Use a Titanium Muffler?

Titanium is highly regarded in motorsport for its combination of low weight, strength, corrosion resistance and heat resistance.

Exhaust systems can add a considerable amount of weight to a race vehicle, particularly when large-diameter tubing and mufflers are used. Replacing conventional stainless-steel components with titanium can help reduce total vehicle mass while maintaining the durability required in high-temperature exhaust environments.

The compact oval design also provides a practical solution where round mufflers may create clearance issues.

Fabrication Notes

This muffler is intended for custom exhaust-system fabrication and requires welding for installation.

Professional TIG welding with appropriate titanium shielding and back-purging practices is recommended to achieve strong, contamination-free joints.

Confirm muffler dimensions, pipe diameter and available chassis clearance before final fabrication.
