VW T1 Bus - T2 Bus - Beetle - KG | Exhaust Manifold 4 in 1 (35mm)

This 4-in-1 exhaust header neatly combines the four cylinders into a single 35mm pipe - providing significant back pressure for improved engine scavenging. Perfect for T1s - Karmann Ghias - and Type 181s that want to breathe a little better without immediately resorting to an expensive turbo. The header significantly improves both your power and sound - especially noticeable at higher RPMs. Combine this with a good muffler - and you'll have a solid foundation for a sweet-sounding air-cooled engine.
