The Stillen SC kit is specifically designed to bolt onto a stock 370Z/G37.
But recommended add-ons are a 2.5" catback and an external engine oil cooler.
A boost gauge and A/F wideband gauge are optional additions, too.
You don't need to make any other preparations.
Stillen advises against headers or downpipe/cat upgrades.
I am gonna get my SC kit early next year, that's the plan anyway
