Im looking for shorty headers for my 07 E63. I am looking into PLM shorty headers or Thunder muffler / Exhaust shorty headers. The Thunder exhaust shorty headers are the ones I am really considering since they are cheap and the pipe diameter is larger than PLM.

My question, will the C63 amg Thunder shorty headers work on my 07 E63 amg?
I contacted Thunder muffler and they said that the C63 shorty headers will bolt up and have no issues at all, its the same motor. I don't believe this. (They don't have a shorty header specifically for the 07 E63 so they said the C63 shortys will work).

I have been doing a crap ton of research on shortys and couldn't find the answers im looking for in regards to this.

I do not want long tubes.

I doubt that the c63 headers will fit. Yes they are the same motor but in a completely different engine bay. Sure they will bolt up to the motor but I doubt that they will fit around everything else in the E bay.

they will bolt up the angle of the down pipes may be different

That is what I was also thinking. The angle where the down pipe connects to the header will be off. Im guessing if they where installed on an E63, the pipes will be off and not able to bolt up.

With your naturally aspirated engine, did you consider going with long tubes? Big difference in power.

I did consider it but long tubes are not the direction for me. To loud, not smog legal and a ***** from what I hear to change motor mounts if they ever need to be changed.

My plan is to do a good shorty header, high flow Thunderbolt cats and a Weistec tune and filters. Figure I can pick up around 40+whp with this plan and not break the bank. I can do all this for just under 3k and do the work myself.
On the dyno I did 5 base runs and my 07 E63 averaged 420whp 379wtq bone stock.
