Replaced the Ebay Catback that came with my 98 GSX. I welded my own 3" piping and then added that. Solid deep tone, I really like it. At first I was concerned because there was a hint that the quality of the Vibrant wasn't much different than the Ebay muffler and it wouldn't last long. After receiving the muffler and comparing it to the ebay muffler, there were obvious quality differences inside and out, particularly the welding.
