In addition to stage 1:

Kit includes:
•HKS Silent Hi Power Cat-Back Exhaust System
•JPerformance Braced Decat Pipe
•Autobahn88 Front Mount Intercooler
•Rolling Road with Before and After Power Graphs

A full exhaust system will lead to quicker spool up time, less lag and more power especially without the restriction of the catalytic converter. The Front Mounted Intercooler will help reduce intake temperatures and increase power.

We will also setup the boost controller and pressure regulator at this point, for the new setup.
