Maybe a stupid question
I have stock pipes and airbo9x on my 08 utra. If I want to install some slip ons and a different breather do I have to modify anything, or change anything? I just want a bit more rumble, a bit more volume and hopefully I'll get a bit more HP in the deal

slip ons, no change needed. A/C and slip ons, then you should get a fuel management setup. I have put IED's on a bud's bike with exhaust and breather and it runs great, he doesn't have a tuner, just the IED's

If you modify the air cleaner you'll be leaning out your EFI. You'll need to get either a Tuner or some XIED's to fatten up the fuel ratio. XIED's are less expensive and will do the job. A tuner is more expensive and really is overkill if you are simply putting on some slip on's and an SE air cleaner.

But easy to install...just plug in and that's about it. If you go with these, I'd suggest placing some sort of cap over the open O2 sensor plugs so they won't get filled with debris.
Good luck!
