The HKS Carbon Titanium Muffler (31012-BA001) is a universal high-performance muffler assembly designed for custom exhaust builds. This is the same premium muffler used in many HKS bolt-on exhaust systems, offering proven performance, exceptional build quality, and a distinctive carbon-titanium appearance.
The 170mm carbon-wrapped canister and 120mm titanium-style tip deliver an aggressive yet refined look, while the 75mm inlet diameter supports high-flow exhaust setups commonly used in turbocharged and high-output engines. Constructed from high-quality materials, the Carbon Ti series is engineered for durability, heat resistance, and consistent performance under demanding conditions.
Each muffler includes a polished stainless-steel mounting bracket, allowing fabricators to weld custom hangers to suit the vehicle. Designed for universal use, it is ideal for enthusiasts building a custom exhaust system that requires premium fit, finish, and sound quality.

High-quality carbon titanium construction for durability and heat resistance
Includes polished stainless mounting bracket for custom hanger fabrication
120mm tip diameter for a bold, performance-oriented exhaust finish
170mm shell diameter with signature Carbon Ti design
