RPM Outlet is proud to announce the newest product in our ever-growing product line, the Fast LSX Lightweight, high-tech manifold. Made from space-age polymer composite material, these FAST LSX multi-piece component intake manifolds show a 20 hp increase on the GM LS1 engine and a 15 hp increase on the GM Corvette LS6 engine, with no loss of drivability or low-rpm torque. Best of all, the FAST space-age composite material polymer intake is 30 percent stronger than the stock polymer unit. Unlike aftermarket aluminum intakes, these intakes avoid becoming power-robbing heat sinks.

These manifolds come with integrated nitrous-oxide injector ports and the ability to accept a larger-than-stock throttle body for increased fuel flow. In addition, the LSX manifolds can be ported, and are easily accessible as a result of the multi-piece design.

Complete Kit shown above. Installation of this intake kit is quite simple includes all of the special parts needed and should take no more than 2 hours to complete.

RPM Outlet is proud to announce the newest product in our ever-growing product line, the Professional Products EFI Fuel Rail Kits. GM factory OE fuel rails provide an adequate fuel delivery system, but when you increase your engines power output or add an aftermarket supercharger, larger fuel injectors and or fuel pumps the factory fuel rails become inadequate. The factory fuel rails become so restrictive, it’s amazing that they will allow enough fuel to enter the engine to produce the amount of power that it does.

Don't waste time and money trying to modify OE fuel delivery components, replace them with a Fuel Rail Kit from Professional Products. The basic kit includes a pair of anodized billet aluminum fuel rails with stainless mounting hardware and polished brackets. Or get the complete kit that adds AN-connector braided stainless hose assemblies and all necessary fittings.

Complete Kit shown above includes a stainless braided -6 AN fuel crossover hose, stainless steel mounting brackets and hardware, plus other necessary fittings adapter fittings to connect to stock inlet and return fuel lines, as well as -6AN and -8AN fittings for those want to plumb their own inlet and return fuel lines

RPM Outlet is proud to announce the newest product in our ever-growing product line, the Professional Products, Typhoon Intake manifold.

This unique new design features a larger plenum volume than stock or aftermarket manifolds, somewhat similar to the 2006 ZO6 manifold. This larger volume is particularly suited to big inch engines but extensive dyno testing on a stock LS1 also shows substantial gains, especially in the mid-rpm ranges. Tested primarily against a leading aluminum aftermarket manifold that is similar in design to the LS6, the Professional Products intake showed equal power on the top end with an additional 12 to 15 hp in the 3,000 to 4,000 rpm range.

The manifold kit includes high volume fuel rails with stainless steel mounting brackets, stainless hardware, and a -6 AN stainless braided crossover hose. Additional fittings are also supplied that allows connection to the stock fuel inlet line.

Complete Kit shown above. Installation of this intake kit is quite simple includes all of the special parts needed and should take no more than 2 hours to complete.
