    In the not too distant future, I'm thinking of some long tube headers and ECU tune on my CLS63, looking for the most aggressive sound and ideally the best gains. Had a look at eurocharged and MSL performance, also header manufacturers such as MBH, anyone any experience with having these mods done? What are typical gains? Thanks
