    Default 2-1 on my 2010 ultra

    Just got my 2 into 1 supertrapp and SE heavy breather installed. Not happy with 18 discs and closed end cap sound. Took off all discs and end cap just to see what it sounded like and kind of liked it. Thoughts? Gonna try 10 discs with open. Gonna Dino tune next week.

    Running ten discs with the open end cap is equal to twenty discs with the closed end cap. The open end cap will increase your sound volume and the flow rate is equal to running ten discs.

    Default No discs

    What if I install the open end cap and trim ring with no discs. How will that affect performance? Will the Dunk help. I like more sound.

    I would suggest you go ride it before spending any more money, the stock ECU will adjust for your changes to run the same AFR as stock. Try it and go from there.

    OK. I have the supermeg 2-1 (black) on now with SE air cleaner. 10 discs open end. went for first long ride yesterday and the HEAT was very bad, almost unbearable at times. Worse than stock cat system. has this been an issue with the 2-1 ? could it be so lean that it is causing heat ? My passenger noticed it also.
