Now that's a TON!!! I talked to some other guys with some hot rods (old guys in their 60's) and they were telling me the a lot of people will get exhaust (big 4 inch or so) and they try to get rid of all backpressure but they said that you wan't to have some backpressure and that it's not always good to try and not have backpressure... Now I am not sure if they were right or knew what they were talking about because I never heard such a thing but maybe someone on here will put their input on this...
Anyone?
