Now if somebody can just fabricate a set that didn't cost an arm and a leg, this would probably be one of the best performance bargains for a Limited and Base engine.
The guy with the SLK32 who is having the headers built by floored fab should be dynoing the system shortly. I mentioned this before in another post that his car is pullied & tuned so the numbers aren't going to be from a stock car. Also the shop is fabricating a completely new exhaust for the car w/low cell count catalytic converters. We should be able to rely on a percentage gain though I would think?
