So the AEM v2 CAI intake is installed (which I strongly recommend) and the VAFCII w/plug and play harness will be going in shortly. As I'm scheduling the dyno tune at my local shop, is there anything else that I should install first before getting this tune? I can't get the exhaust system now, so I was considering throwing in a testpipe. Worth it at this stage?

Are any of the popular S2K exhaust systems ready for the drop in testpipe without cutting the pipes?

Thanks,
