well thanks for the help so far, i took the truck out for a drive this morning, it seems to rune fine. The noise was coming from up front towards the fan, either a bearing or a belt, but i sprayed it down and it stopped for now, ill keep an eye on it.
as far as the exhaust goes, truck is sluggish on bottom end but i can deal with it, it runs better than before im just wondering if it was a mistake to up the size of the pipe. It seems to have destroyed my gas mileage though, which sucks because it wasnt that good to begin with.
just one last question, will placing a cat back in instead of having a straight pipe help boost my mileage a little bit?? something like a flowmaster aftermarket cat or something
