1. Gruppe-M and AFE make CAI's for the car. Others will probably follow soon. We got 10hp gain from the Gruppe-M CAI...but it's very pricey @ about $2400.
2. There's MANY exhausts to choose from. I'd recommend a 'downpipe-back' exhaust with high-flow catalytic converters. Expect to spend about $4500 here.
3. ESS Tuning has just introduced their ECU reflash -- saying it will gain 20-30 midrange hp, and 10 hp at the top. It's $995, and you'll need to remove and send them the ECU and they'll send it back. Dyno charts of this ECU reflash should appear on this forum in about two weeks.
All three of these things together will be a great combination.
Thank you, The only question then, who makes the best all around exhaust?
