Hello Not sure if this is the right place to post this here. i'm looking at a new exhaust on my OM642 engined CLS, for a little more performance and nicer soundtrack and because I want the AMG styled quad tailpipes (ones on the car need replacing anyway because they're pitted with marks that I can't polish out! (after painting all the front end to remove stone chips and a good machine polish it's really bugging me!) Anyone have any recommendations on what to do? luckily it's a non DPF model, and I am considering a hybrid turbo, the car is currently mapped and the map will be adjusted to match the new hardware. I've considered removing the rear silencers or changing for smaller ones, gutting the secondary cat, an X pipe in the middle? not looking at making the car stupidly loud, still a nice comfy Mercedes after all but it's just a little too quite for my liking when floored. Thanks in advance!
