I currently have the Lotus sport exhaust (stock headers, stock downpipe and stock 3rd cat). I'm considering getting either the Larini or 2bular decat (that removes the 3rd cat) and sticking with the stock headers and downpipe. I'm not in a position to do a full exhaust swap right now, so it's the decat or nothing right now. Does anyone else have that setup? Did the addition of just the decat make a noticeable difference in the sound and performance?
