    ok... so I've been thinking now that I have my exhaust on order. How does upgrading our exhaust.. give us more horses??

    I mean.. I am cutting the mid resonators.. and running straightpipes from there (2.5 inch diameter) to 2 magnaflow mufflers.

    Anyway.. how does this give us power? it seems to me that we would loose power from it because now there would be less back pressure that would drive the turbines?

    Am I right on this? orrrrr? any thoughts? comments?

    turbos do not like back pressure, this is just a myth. why do you think people running turbo cars on the strip run open dumps, no restriction. Our engines are air pumps, the more air we can get in and out the faster we can go

    2nd that, like I said, turbos dont require back pressure via the exhaust system
