Valve seat Performance Products has introduced its all-new Ultra Street Avenger and Ultra Double Pumper carburetors.

 They're designed for improved performance, weight savings, and show-quality looks, and their all-aluminum construction makes them 5 pounds lighter than their zinc predecessors.

The Ultra Street Avengers come with vacuum secondaries, are available in 670- and 770-cfm sizes, and have all of the bolt-on-and-go features that made the original Street Avengers so popular.

The Ultra Double Pumpers are available in 650- and 750-cfm sizes and come with mechanical secondaries and electric chokes.

Both Motorcycle Carburetor types feature four-corner idle circuits for precise tuning and enhanced fuel curves for optimum performance.zjautoparts for all the details.Billy Boat Performance Exhaust has released its Fusion bi-modal exhaust system for the C5 Corvette.
