I have searched for a while now but I can't seem to find what I'm looking for.
I have a 1983 300SD that will make the Mercedes purist hate me, I made the exhaust exit through the hood (sounds pretty cool) Also I have cut the springs to lower the car a few inches. Now for what I would like the car to do..... I have already removed the ALDA but I want the car to blow more black smoke maybe even "roll coal". More power is a plus I'm not too concerned with MPG as the car is now it gets 20 in the city and 25+ of the highway. Something to make the car a little faster off the would be great.
