I have not experienced any kr and drove the car with the 3.4 pulley and thrasher cai for the last few months of the summer. I have decided to purchase the slp header, U-bend delete, and Overkill Pcm. I will keep my fact. cat...and exhaust until I see how the car performs this spring. I can't wait to get the work done. I will be doing the work myself, How difficult is changing the headers? It doesn't look that difficult. Does anyone know an estimated 0-60 time or 1/4 mile estimate after this work is complete?
