I just bought a set of vance and hines Big Radius 2 into 2 pipes off eBay for my 2012 Streetglide. The add and the guy I bought them from swear they came off of a 2010 Streetglide. So they should fit. My question is: If someone has installed these, where were your o2 sensor holes. This set I have they are right under where the bolt to the heads. My factory pipes had the o2 sensors right next to the transmission cover.

 

More than likely they are for an older harley. The ones I bought for my 11 had the o2 sensor bungs at the tranny cover. Most people plug the o2 sensor bung and run a aftermarket tuner with new free flowing exhaust. Newer bikes have the smaller sensor. Don't remember off hand when they changed the sensors

 

It's for an '09. I have the Dresser Duals and had to order an '09 header pipe for my 2011 to accommodate the larger O2 sensors for the Thundermax auto tuner I bought.

2010 and up have the smaller sensors near your right foot.

On the positive side you can still get an autotuner that will work with your bike. On the negative you'll want to remove your old ones that are in more stealthy location.

 

The '10 models were the first year for the new 12mm sensors. On stock pipes, they are at the collector near the clutch cover. The Big Radius 2-2, I've installed three of them, has no collector but the ones for the '10 up did not have the sensors up at the head like the earlier models did that had 18mm bungs. Those that run Power Commanders etc that have the sensors disconnected can mount any pipes for the new 09 up frame and have them work as long as you aren't plugging in sensors. So yes, he may have had them on a '10 but those pipes may not be for a '10 and newer with the 12mm bungs in place

 

I installed a set on my 2011 sg and they were in the same spot as the OEM are.

 

Thanks guys! With help from y'all and the guys at Vance and Hines I found out the guy got me. The pipes he sent me were for an 07 Dresser that somebody customized to work on his '10. Instead of him looking at part numbers he assumed on what they and took the part number for 10 to 14 off of Vance and Hines site, which in turn screwed me! The guy is not wanting to cooperate so I had to file a case on him with eBay!
Thanks Guys!!

 

I ended up forking out the extra money and just ordered myself a brand new set from J&P Cycles! Hopefully I will get my money back from that guy soon!

 

I would have just put plugs in the buns and added the newer buns at the clutch.
Been a lot easier and cheaper.
Any muffler shop can add the buns for you.
