Hey Guys,
My '03 F4i came with Erion Racing exhaust. How can you tell whether it is slip-on or full setup?
I am not sure which one I have. (On my Hayabusa, it is easy to tell because the retainer springs have the Yoshimura emblem stamped on all of them)

The reason I am asking is that I ordered Power Commander yesterday. There are two separate maps on DynoJet Web site, depending on the answer of this question.

At some point I will have the bike custom tuned at a shop perhaps late next year. But until then I will utilize the maps on the Web site.

Another question, I have about 20K on my OEM filter. I think I will order a K&N one as well, since it is about the same price as the OEM one @ $36. There is no map for this combination on DynoJet Web site (i.e. Erion ex. + K&N filter). Any suggestions as to what to do?

Thanks everybody!

 

Pictures of the exhaust under the bike?
I think a bunch of people on here can answer your question in an instance then.

 

Full exhaust includes headers. Slip on only includes midpipe and muffler canister. Look at your headers, compare it to pictures of stock bikes online and you have your answer.

 

Thanks guys! Great suggestions. It looks like I have got the slip on kind. Power commander seems to work fine so far. (1st day with it commuting to work). On/Off throttle response smooth transition what I noticed so far.
