Kleemann M272 Headers
Does anyone have this kit installed on their 230 yet? I wonder how much this costs including installation.....

Totally agree, if you want to do the stoplight drag race, get a Mustang, there is a well known term called American Muscle and there is a reason why this is attached to several domestic cars.
The hp claims from aftermarket always seem exagerated, I mean 30+hp just from a change in exhaust and headers?? I know from my experience working with British sports cars looking for extra hp from my TR6 that unless you address both sides of the engine the gains are minimal. In simple terms in order to blow more (exhaust) you need to suck more (intake). For my TR to suck more that means more than just adding a K/N filter, it means adding header type intake manifold with multiple carbs (read as triple 2 barrel Webers) and a high lift cam.
Chips can change the engine output but I think that headers will only add 3-8hp in real world terms (and I am being generous). In most times with the new sound you feel that you have more power.
About a year ago the connection broke between the manifold the front exhaust pipe in my Acura and basically it was like open headers on that car. The noise was incredible but there was not huge noticeable increase in power or torque from the engine
Modding is fun and a great hobby, just be smart on some of the advertised claims and the cost effectiveness to get there. As someone who works in the ad biz just remember that these company's business is to sell you the goods.
The cheapest effective gains will be felt through upgrades in suspension, brakes and tires, if measuring in a closed circuit such as a track. You will cut laps time more significantly with these mods.
