I'd love to see a dyno test of the Fitch Fuel Catalyst. They've got some pretty reputable sources saying it works. But then, it wouldn't be the first time that happened. Tornado Fuel Saver anyone?

ok board tonight, decided to write this up
seems backpressure is a huge issue in here, lets start with why backpressure is good, in alot of vehicles produced since we started worrying about emmissions keep the exhaust valve open for an extended amount of time to burn that little bit of gas more completly, with this, u loose compression inside the cylender without some backpressure. lets talk about big pipes now, big pipes increase the volume of ur exhaust and they decrease the velocity of your airflow meaning more heat loss over the same distance of pipe due to lower velocity inside the pipe. in situations where the pipe is shorter (less distance for the air to cool) or a larger volume of gas is pushed into the pipe (more gas==higher velocity), larger pipes are acceptable this is why top fuel dragsters have huge pipes (around 500ci + much boost).
with all this stated unless ur exaust goes straight out ur hood and u have a cam with a short exhaust duration backpressure is good
next up is the fitch fuel catalist, does anybody else think this thing has a big resemblance to a fuel filter? im thinking maybe it is just a second fuel filter, getting out more particles of crap, keeping ur injectors cleaner and getting a better a/f ratio due to less particles of crap in the combustion chamber, price is $177.45+$14(shipping) really expensive fuel filter.
ok now the reason i came on here in the first place, some fun reading
i cant believe i seriously read the whole article, it was written by such a complete idiot. i love to read what idiots write its hilarious, but this was over the edge, i lost iq points reading it.
