Axle back exhaust
Perrin Performance drop in air filter
Would I go with a Stage One from Cobb or use the Stage 2 mapping?
I'm saving all my pennies right now for an AccessPort but I've already got the Perrin filter on the way (bought it before I did any research). I've also found an axle back exhaust (from fastwrx.com) on sale for $225.00. I'd really like to improve the sound of the stock exhaust.
If I use the Stage One mapping, will it be the right one for this setup?
