I know I have seen this debate rage on in the past but it is now that my stock muffler is in bad shape. It appears that there are generally three ways to go. 1) stock 2) Borla or another type of cat back system or 3) Flowmaster. The Flowmaster is appealing because of its low cost vs. the Borla and factory replacement. Has anyone gone the Flowmaster way and if so what type is used? Inlet/outlet diameter and placement or just a part number. Of course if anyone has a really good reason to go another way, by all means please let me know.
