Honestly the headers are quiet expensive but Evosport just released their version of the headers for the 350 SLK and you should enquire last time I recall it was cheaper than the Kleemann and other European tuners offerings. The headers will give you the most as an example for the SLK55 headers give 20hp and 20tq. The ecu upgrade costs around 600 dollars if I am not mistaken and a vendor in mbworld carries it, I think its euroelites as they also carry Kleemann, Evosport products.
The exhaust system can be purchased online but I would reccomend the Peicha products as they are top notch, you can contact member noregret4life for the Peicha upgrades.
