info on secondary cat bypass pipes...
Hi people. It's my first post on the forum so il start by saying hi and thanks in advanced for any help or info. I've just bought a c63 amg and although I love the sound I'd like it just a bit louder when cruising around. I haven't got the money at the mo to buy a full system but I've seen you can get secondary cat bypass pipes that are a reasonable price and aparently sound good? My car apparently has been re-mapped so will I need to get the map tweaked after this mod? Oh and will it pass an MOT? Any other suggestions on making the car allittle louder without to much expense? Cheers ben
