09-13 LS9 Power Package

You may think it would be hard to improve on the very potent ZR1 Corvette with 638 hp, but it is possible. The Corvette engineers did a fantastic job of bringing us an awesome car, but they also gave us something capable of more. This LS9 Stage 1 performance package brings together our exclusive set of Kooks R-Series stepped headers and high flow catalyst backed by a Corsa exhaust system to give the ZR1 some authority out on the road. Along with a supercharger pulley kit, Mamba fresh air scoop, shielded wires to keep the heat off and some calibration changes in the PCM, this performance package will turn your ZR1 Corvette into a 700hp beast. You will also notice quicker acceleration thanks to an additional 5lbs of boost and free breathing on the back side.

This kit is not recommended for the DIY as a press is required to complete installation.

Modified Corvettes tweak of the already formidable ZR1 Corvette includes:

* Mamba fresh air scoop
* ZR1 Corvette supercharger pulley upgrade kit
* Special High performance Shielded Corvette spark plug wires
* Custom PCM programming
* Kooks R-Series "stepped" long tube Corvette headers
* Kooks high flow converters, street X-crossover and mid-pipe
* Corsa Z06 & ZR1 Corvette exhaust - 3" Sport cat-back exhaust system

Note: Stock ZR1 Corvette PCM must be shipped to Modified Corvettes, LLC for upgrade.
