greddy universal

[Murcethecurse]

Im still debating on waiting for the invidia exhaust or just go with the greddy universal ti-c with burnt tip 80mm and get a 2.5 straight pipe. or does anyone know which gain will be better greddy or invidia?

Most likely the muffler itself won't really dictate it too much beyond the sound. It'll be the diameter of the exhaust pipe, and if you run a downpipe/no downpipe that will determine gains. I think most of the downpipe dyno's showed like ~20hp with a full catback. Installing just a catback may yield... 5-7hp?
