Hi was wondering if I could install the rush 4000 series
mufflers on my 08 street glide I found a set reasonable
so thats why I am leaning towards them I dont want to spend a load putting on power commander will this work
on a budget??????? or should I keep saving ??I dont want to screw the engine up thanks

 

Just mufflers, yes. You only need a fuel management when you change the air cleaner out to a high flow (stage 1) along with it. You're fine just changing mufflers.

 

thank you I have been worried did not want to fork out 500 rt now thanks

 

Rush mufflers for your SG is 13305, or 2HS05 depending on what size your header pipes are.
These mufflers will take the 4000 series tips that goes on the ends of the mufflers.
www.epiflex.com is their web site or do search on Rush Harley mufflers

 

Rush sent out a service notice about six months ago recommending the Stage 1 download for '08 and '09 Harley V-Twins on muffler installations (even if the air cleaner remains stock).

One of my fellow riders in the Roanoke area had bluing on his mufflers when he changed to Rushs and did not do the download. The Harley dealer in Roanoke (Virginia) is recommending the download.

The tech that works on my '09 Street Glide says the newer bikes come from the factory on the lean side because of emissions limits.
