Hi everyone i picked up a 2002 f4i a few months ago and it came with an Erion slip on. ive been thinking of switching to a Level one racing exhaust. what is everyone's opinion? i have a power commander and bmc air filter and I am not taking the bike to the track currently if that helps. not much information on the forums for either exhaust so any help would be awesome. Other suggestions are welcome as well.

Thanks!

 

I'd used that money to do something else on the bike. Is the power gain worth the expense considering you've got the set up you have already? I'd look at sliders, undertail, new gear, etc.
