I put a pair of Rush slip-ons on my Nightster as soon as I got it home from picking it up. I was pretty disappointed riding it home, felt sluggish and unresponsive and missed any real note. Slipped the stock ones off and put the Rush on and bang - huge difference in response and awsome note. No other work required but can do the breathing etc. later if I wish. The performance is a big difference, really responsive and sharp compared to the stock pipes.

Not sure if that helps at all?

Bernie, What did the Rush slip ons cost and where do you get them, thanks Jim

Hi when i first picked mine up i had se mufflers on it wasnt real impressed with them so i put a set of v&h shortshot staggered i can tell you if its loud you want there the pipes how ever i have chrome sprocket and lower belt guard the heat from the pipes discolours them they polish up ok but its becoming a pain so i am interested to hear other options ive never heard of rush before can you give me more info thanks.

I have a set of Outer Cycle slash cut mufflers off my 08 1200c.
These are really loud, and draw a lot of attention. But the increase in performance is awesome compared to the stockies.

I have posted them on the "Parts and accessories for sale" forum

dav66h, where did you purchase the Rush pipes? how much.

Sorry I mean burnie

Hi why are you selling your mufflers sprocket

Jim, got them from GC Harley when I bought the bike, $482- for the pair new.

s@s slip ons r worth a mention ,you dont get mainy gains in hp ,with a new set of pipes ,slip ons probably give more where u need it,
