I'm a bit confused. I'm looking at buying a Supertrapp Mean Mothers II exhaust system. I noticed though that their are two versions for my bike (08 FXDL)....one with an O2 sensor and one without. Which one is right for my bike? I'm waiting on a call from Supertrapp but meanwhile I'd like to hear what some of you say.

On once I get this out of the way I'm going to figure out what I'll do with my AC and then orderi my PC V. Thanks.

 

I would imagine if you have O2 sensors, you need the O2 bungs. If you're running a PC3 like me, you don't use the O2 sensors and wouldn't need the bungs. I would also imagine your PCV would not use the O2 sensors either.

 

08s had 02 sensors. You can turn them off if you really hate the looks (if you have a tuner), but that would be a little stupid... they provide a valuable service...

 

get a pc111 or v then you wont need the 02 sensors

 

With a PC lll or PCV you get O2 elimators so you dont really need the bunges. That said since you are getting a PCV, if you ever want to add the auto tune then you will need the bunges. It gives you new better O2 sensors to use.

So my advise is to buy them with just incase. Its alot easy to plug them than it is to add them.

 

Thanks guys. If the exhaust with the O2 sensors wasn't $100 more I would have went with it but I instead I ordered the one without (they were both $649 directly from Supertrapp but Dennis Kirk had the one without for $533) . I hope I don't end up regretting it....don't think I will though. Now I have to figure out which stage 1 AC I'm gonna go with. The Arlen Ness Big Sucker is one option but I really like the Roland Sands as well. I like the black and chrome one. Any suggestions for a AC?
