@Puffwagon do you know if fg mid muffler is straight through or a bit restrictive? Im thinking of getting my exhaust engineered a bit, so iv already said before, but I have 4inch dump and 4 inch all the way to the 3inch flange under the car, the wg pipe plumbs into the 4 inch under the car. What im thinking is, to extend the 4 inch all the way to the mid muffler and put a flange before the muffler to step it back down to 3 inch, but also make a mid muffler delete 4 inch pipe that bolts up to the 3 inch flange that's after the muffler so I can experiment with and without the mid muffler and still retain the stock last 3 inch bit that goes up over the diff. It would effectively be a 3 quarter length 4 inch exhaust. Would it be any less restrictive by doing that? Or would there be no difference because of the last 3 inch bit? Another thought I had was to not plumb wg pipe back in and run it separately as far as I can under car beside main exhaust and point it down at the end. I could only make it get to before the back wheel, it cant make it go over diff cos of room. Would it be just as noisy as a full on short screamer pipe? A separate wg pipe would effectively de-restrict the main exhaust and it wouldnt need to be upsized.
