I had the stock muffler replaced with a Flowmaster Super 44 and noticed no change in seat of the pants power. After running it for about a year I had the Flowmaster removed and welded in a Magnaflow oval 18" muffler....the rest of the exhaust remained stock. I can honestly say that I felt a small increase in low end pull on the seat of the pants meter. It wasn't huge or anything but I noticed it. The best way I know to describe it is that the truck seemed happier, lol. As a bonus I also picked up about 1 MPG or so. The 2004 hemi I have now had a Flowmaster when I bought it but I will be replacing it with a Magnaflow muffler and y-pipe when I get the coin. I don't have any experience with the y-pipe yet but if you crawl under there and look at the stock one you will see it is extremely restrictive. Hope this helps.
good advice! thankyou
