A word about our cars and the Mercedes Siblings...

I used to have a friend that worked at a Aftermarket/Tuner store in Orange County for BMWs and Mercedes. Those people generally don't have a problem dropping big bugs for small gains or anything that will make the car look/sound more aggressive and remain classy.

Good example... The shop was sent like 7 different exhaust for I forgot which car, some of them being around $1,600 and none of them made more than 7 RWHP over the stock system. They had bigger exhaust tips in pretty chrome and sounded beefier. Again... as a rule of thumb once you get over/near 300 RWHP things start to get very expensive.

For anyone who removes the heads or does an engine break down - Ceramic Coating the pistons heads and valves should yield 15-25 horses and not all that expensive if you're already doing a breakdown.
