how do you know that chip actually works? do you have dyno charts to prove it? doubt it, and i doubt it even works too. and that f22 isnt fast bro, its a sohc engine in a heavy car. im not trying to bash preludes or anything but thats just like saying the D15B8(the slowest motor in the civic) is fast. and for that muffler, just throw it in the trash immediately because you wont get any power from a 3.5 inch muffler. you need to buy some lager piping to go along with it.
oh and how do you know how fast it is? have you ever driven any other cars in your life? you sound like a 16 year old kid that just got his license and "races" peoeple at stop lights and puts his hazards on after he "wins". just had to get that out of me sorry guys, whew im done.



oh and it's HEADER not headers, you dont have a V-type engine.
