I just found a pair on ebay for 20 bucks. Do I need to do the remap on my 2005 EFI? If so will the dealer install the pipes? And, I might as well do the air filter thingy and call it a stage one. I don't want to take chances o voiding the warranty. I just some louder pipes. Thanks in advance for any replies.

 

Usually with just mufflers you do not need a remap, but you talk of the air filter also, so a remap IS necessary then with both or you can use a TFI or PCIII to richen things up here, look in the do it yourself forums to get an explination of these.

These bikes run on the lean side anyway so a good choice would to be to install something that would richen it up a bit.
