Your stuck with shorties if you want to keep the stock cats. If you do not mind HFC's with long tubes, then you have a few options. 1: Motordyne E370 with HFC option, 2: Motordyne XYZ Y pipe with HFC option, 3: Fast Intentions CBE with HFC option. If you are sticking with shorty headers, save the coin, only the Momentum DE headers really make powerand they won't mate with the stock cats, doesn't help they are out of business too and you would be on Z1's time table for the new ones to be released. The stock headers are really good for shorties FYI.
