Step = Giant Leap
We're talking power gains here for '05-'07 LS2 and '06-'08 LS3- and LS7-powered C6s, thanks to "Stepped" headers made by Kook's Custom Headers and available exclusively from Zip Products. Their design melds the particular advantages of specific tube diameters: low end torque from 13/4-inch primaries at the flange, then opening up to 2-inch tubes for unrestricted top end. They're manufactured from mandrel-bent 304 stainless steel with 3/8-inch flanges, 3-inch collectors, and O2 sensor bungs as original. To complete the installation, upgrade your Corvette's midsection with a Kook's crossover pipe, center section, and high-performance converters (also available from Zip).

More For Your C4
Keep your C4 on the cutting edge of technology with Edelbrock's latest cylinder head: the RPM Xtreme for LT1- and LT4-powered Corvettes. Combining the affordability of as-cast ports with custom CNC porting in the critical areas (combustion chambers, intake entry, exhaust exit, and intake/exhaust bowls), Edelbrock improved air flow and overall performance. How much? How about up to 76 hp and 50 lb-ft of torque over stock. These heads-available either complete or as-machined casting-use LS1 valves and conical springs for improved airflow and high-rpm valvetrain stability. The RPM Xtreme will bolt right on to your '96 LT4, and will also fit '92-'97 LT1s if you use the LT4 intake manifold.

Make your '08 Great(er)
There's nothing like a new car, especially a new car like America's Only True Sports Car. That's why the folks at Breathless Performance Products developed their Vortex Ram Air Induction System for your '08 Corvette, one that delivers power gains from 12-25 hp just by bolting it on. It scoops in cold air from outside, while sealing out hot underhood air better than the OEM induction setup. The system comes complete with the Vortex Ram Induction Box, Powerduct, and all install hardware and it doesn't need a throttle-body spacer.
