Exhaust Question
My dealer told me I could not add JUST slip-on mufflers to my 2006 FLHXI. He said I would also have to add the tuner thing for the computer to compensate for the freer flowing exhaust. I just want more sound, performance is adequate. Is adding aftermarket mufflers to an otherwise stock TC88 a bad thing if that's all you change?

you can swap slip-ons just fine without anything additional. if you change the header you will want to change to a high flow intake air cleaner and change jets for carbs or get a fuel management system if it's fuel injected.
Dude,
Your dealer is LIAR!!!! Bought my Limited with 10 miles on it, chandged out the stock mufflers after 500 miles, Never an issue. Runs and sounds good. will sound better when I have the head pipes changed and new Air added, but must retune after these mods are done.
But little advice, which I have been given here on this site, and that is to go out to your dealer, bike show, bike rally, poker runs, and listen and ask questions about what people have and are running. Good slips can run as close to 500.00 dollars and some add HP and Volume and some just sound good, I guess. I went with Klock Werks; great sound, a little bit of power and a great look. Long 4" straights. IMO great Pipes!!!

Your dealer is technically correct. Any time airflow in or out of the engine is changed, you will see more benefit if your programming is modified to take advantage of it. With that said, your bike will run fine just swapping slip-ons. You don't really get into an issue of "need" until you change the air cleaner.

It will run so much better doing the tuner and a/c, so why not just do it. You might think it is "adequate" now, and it surely is. But a little money goes a long way here.

That makes sense. And just to clarify, dealer wasn't saying adding a tuner was a good idea to take full advantage of the exhaust. He was saying it's necessary to avoid leaning out the a/f mixture and doing bad things to the engine.

You maybe correct in the long run, but I'd hardly say it's a little money though. Just to dyno tune my bike alone cost more than your average slip-ons, then you have the cost of the air cleaner and tuner on top of that. No, it wasn't cheap, but I certainly thought it was a worthwhile performance upgrade.
