Handmade Performance Exhaust Purbalingga, Indonesia

Grumung Exhaust is a handmade performance exhaust brand under Grumung Garage, with 9 years of experience in exhaust fabrication and custom builds. Every Grumung exhaust is built by hand, giving us the freedom to create custom systems around the vehicle, application, and desired sound. From daily drivers to street performance builds, we build exhausts with character.

Built with the freedom to customize size, shape, configuration, fitment, and sound for every vehicle. Each exhaust is handcrafted using T201 Stainless Steel, argon welding, and polished finishing, with custom header configurations such as 4-1 and 4-2-1, plus fully custom mufflers built from scratch without fixed templates. Built around the engine. Your Car. Your Sound. Your Build.
