These beautifully constructed Carburetor Air Horns out-perform mass-produced stock air horns, significantly improving air flow into the carburetors and resulting in power improvements. They are designed and machined to exacting standards for optimum flow in the shortest possible height. Sleeve-mounted horn installs in the Weber 45 DCOE with no modifications, using the stock Weber hardware.

The sleeve outside diameter is 48mm. The exponential radius provides a bell OD of 2 7/16" with just 0.95" exposed height. Sold individually.

For a low-profile, free-flowing air filter, we recommend our Custom Filters for 2 1/2" Velocity Stacks, Part No. 3894-64 (sold separately).

Velocity stacks and air filters


Basically, good product and excellent service (as always with Pegasus). 3 small issues: 1. one stack was bent in transit 2. Gauze air filters are too big to sit firmly on stacks 3 Packaging was 3 times as big as needed = very expensive o'seas freight.
