Hi At the start of a long term project Any advice on mild tuning for these? I plan to make a SS exhaust as the current one is a bodged decat Was going to use a free flow sport centre and backbox. Too loud? Anyone done this? Heard a rumour there is some merit in fitting the CLK55 air box Is this true? What's the difference? I do like induction roar, but the position is not ideal for a cone filter. I'm not a boy racer, just prefer freeing up some V8 noise! And will only use the car for a couple of thousand miles a year.
