Guys I have a 2013 C63 sedan and I am getting both eurocharged ECU remap upgrade as well as ipe full system exhaust for my car. The remap is already here and exhaust will land by next week. But I am a bit confused about which of those I should install first ?? Any suggestions??

Install the exhaust and then let EC know that you now have an exhaust and they will send you a new file.

I can't hurt to put the tune on first if you don't have the exhaust yet. Have some fun with the tune if you got days or a week to spare. Normally I would say the exhaust and then tune if the exhaust was going on straight away

Sure, do the turn now and have fun with it, but Autosport is correct as EC can modify the tune based on your setup. So they may make modifications to the tune based on your revised setup (at least that's as much as I understand it). But V5 sure is fun!

Put the tune on now to enjoy while waiting for the headers to arrive and be installed. Then you will have an idea of how each affect your car's performance. If your tune is not already adjusted for headers then ask for a header tune to install after the headers are installed. That is what I did as well.
