I did the EXUP delete myself, even removed the flapper valve in the header. Im also running A&R baffles, and a gutted Y pipe. Its breathes like a FULL system now for a fraction of the cost of an Akrapovic, for example....... I obviously had her dynotuned with the power commander due to these changes and let me tell you, she is a beast! She "only" made 150 horses at the rear wheel. lol I know some guys talk of bigger numbers in the 150's but im pretty happy with 150 and my set up. instead of really coming alive at 9K rpm's, its more like 7K and the front wheel is coming UP quick.
i say delete it all as long as you have a PC3 or 5 to get it tuned for your air/fuel ratios.
