Found a sweet 2010 FLHX , but I hate the 2-1 exhaust , can find plenty of stock exhaust systems off 09's and was wanting to know will they bolt right on? Planning on buying some off CList and put some slip ons on. THANKS

 

Im thinking they will, but i think 09 O2 sensors are big on top and 10 O2 sensors small on bottem.

 

Correct - different size O2 bungs & changed location. If you plan on adding tuner to bike - then this won't matter b/c O2 sensors get plugged & capped...

 

Have patience, soon there will be plenty of stock 2011 exhausts for sale. Like mine.

 

I found a set of brand new pipes off a 2011 Street Glide FLHX a dealership had took off on E-bay for $140 (plus shipping $49). I have a 2010 like you. I just got them yesterday so I'll look closer to the co2 ports when it warms up later this morning. Plus I have to go buy about $30 worth of clamps and hangers at my local dealer. But BEWARE if you do find some, that the seller wraps the pipes in towels or something to protect the chrome!!! My mufflers were scuffed in shipping because some highschool kid threw them in a Vance & Hines box and shipped them with nothing to protect the finish. Fortunately the mufflers took the brunt of the scratches and the vital head pipe/heat shields weren't bad. I believe I can swap the rear shield (lite scratches)with my stock 2010 shield. I did however call gothd on E-bay and they refunded my shipping. She was very nice and apologetic. I'm ordering some 3 1/2" Rinehart slip-on's with those cool Arleness tips next week so the mufflers didn't matter too much.

 

Yes, you can do this. It is a great idea because the '09 doesn't have the CAT in the headpipe. All the newer models do. The stock '09 is actually a good head pipe that helps produce a good bit of torque.

 

In the what it's worth dept....I did bolt a set of 2011 Streetglide pipes right on my 2010 Streetglide with absolutely no problems...everything matched up perfectly...which is great if you don't want to spend lots of $$$ and want OEM stuff...but thats just me

 

Really? I've never plugged and capped O2 sensors to use the HD tuners or the TTS Matertune.

 

I have a 2010 FLHX, with 09 head pipes and rush slip on's. I also have a PCV with autotune, so the answer to your question it does work. BUT the O2 sensors will be an issue as all ready stated.

 

The PowerCommander V has you remove the wires to the CO2 sensors when you install it... I guess the PCV does it's magic without them if you have the right map... I was a little skeptical at first but seems to run OK. My worry is that the PCV comes with wire caps for the main bike wiring harness but not the stock CO2 sensors.. so the bike's wires are protected from the elements but not the sensors... I guess they want you to buy their auto-tune setup which replaces the sensors...
