mercedesclk320

Hello everyone, i am currently looking for some kleemann headers for my clk430. Apparently i cant buy the e class one since the clk exhaust system is unique to its shape so im gonna have to go with the picky select here. Im ready to buy a good solid set and id really appreciate the cooperation of anyone who is reading.
If possible, also thinking of getting the LSD and the supersport camshafts (eventually im getting the s/c but ill stick with the little things first). Im putting the car together and my god it runs well. Anyway thank you in advance!
