CSP Products and JPM teamed up and designed a revolutionary exhaust system for strip and street use during a two-year development period. It is especially made for Type-1 engines.
Until the launch of the CSP Wasp exhaust system in 2013, there wasn't a stepped header for air-cooled Volkswagen available – this technology really produces horsepower. Three different pipe diameters, getting larger towards the collector, optimize the volumetric efficiency. Options include a specially made megaphone, or alternatively a muffler. These are no universal parts! We designed and engineered three different megaphones and three different mufflers for the three versions of the CSP Wasp exhaust systems! Whichever option you prefer, both – the megaphone and the muffler – create a strong suction over a wide RPM range, which helps cleaning the primary pipes from exhaust gas particles.
Result of our efforts: The 2276 cc test engine had a performance increase of 13.5 hp just by installing the CSP Wasp exhaust system!
But it wasn't all about horsepower in the specification book of this exhaust system, it was also about easy assembly. As with any high-performance header, you have to go without the heater channel tin, but the rest of the engine tin and the car’s body can remain stock.

Here are the features of the header at a glance:
three-step header for improved volumetric efficiency, made out of 1.4301 stainless steel
equal-length pipes
moveable header pipes match every engine width
painstakingly manufactured collector
lambda socket welded to the collector
solid, laser-cut flanges, CNC-ported
for Beetles with Type-1 engine
fits with stock engine tin without heater channel tin
fits without body modifications
available as:
- Wasp Stage 1 (up to 230 hp)
- Wasp Stage 2 (220 to 290 hp)
- Wasp Stage 3 (from 270 hp onwards
