Anyone have any experience with headers on M37? I am in process of putting together a full custom exhaust to get ready for tuning. I can find ZERO header options for these things. I would think most headers for the 3.7 would fit as the engine bay is larger than say, a 370 or G37. I have also found some made for a Q50 so I would think those are pretty close in size. Any help or advice would be greatly appreciated.
