Finally got me a set, coming tomorrow. Should I pull the Maxi Fuse before I start pulling things apart? Also, would it be okay to use PB Blaster on the head nuts, they look kind of rusty?


I guess I need to contact Dynojet Power Vision for another caned tune, or just do the auto tune again?
I'm also hoping I can get the stock system off as one big piece with the cross over.
I may have a set of V&H Straight shot HS slipons for sale soon.

 

You probably should pull the main fuse before doing anything... I personally did not pull it and just left the key out of the ignition. You will also be fine using PB Blaster on the flange bolts (I did so), just be sure to put a rag or something under the bolts so it doesn't drip all over your motor.

I would also get a new map from Dynojet or Fuelmoto (if you bought from them) and then run some auto tunes afterwards.

Mine is a 2011 so I'm not sure if yours has the same stock exhaust as mine but my cross over was built into the exhaust mount and it did not come off in one piece but did come apart easily.

 

Thanks for all of that. I was starting to think no one was going to reply. Thanks again.

 

Man, what a nightmare it's been getting the old pipes off. The old exhaust gasket are a pain to get out too, what am I doing wrong. My neighbor says they look like they are pressed in behind a ring of some sorts. This is my first times doing something like this. Please Help!

 

Never mind guys. That metal ring around the exhaust gasket my neighbor said he seen is part of the gasket it self. That's what it shows on a bunch of pictures when I Google it. I have a tiny screw driver I can stick under it.

 

I saw some videos that used a dental pick looking thing that they stabbed into the old gasket and then it came off that way.. It was kind of a pain but I was able to get an automobile trim remover in there and was able to pry off the gasket with that.. Or a small screwdriver would probably work just fine. Just be careful though, the metal around the gasket seems very soft and will scratch easier.

Not to be the bearer of bad news but getting the new gaskets in is wayy harder than getting the old ones out.

 

Yep, I'm worried about that too. Sorry, I don't believe people that say they do all of this in 3 hours, took me that long to get everything off. LOL

 

Oh by the way. I kind of put a small oil stain on my front O2 sensor when I almost dropped it undoing it from the front pipe. Anything to worry about there.

 

This was the first time changing pipes for me also and it took about 4-5 hrs. I do think that if/when I do it again, it'll go a lot faster since I have somewhat of an idea of what I'll be doing, so maybe 3ish hours will be a goal to aim for.

I can't really say for sure about your O2 sensor. I'd clean it off as best as you can, put it back in with the new pipes, and see if your bike throws a fault code. Worst case scenario, you'll need a new sensor, or it'll be fine. Even if it does ruin the sensor, it shouldn't hurt anything but it will effect your autotune if it is damaged. When I bought my bike, the rear sensor was disconnected for some reason and they cleared the fault code so I didn't even realize it for a while till I found the wire tucked away and wondered where it belonged.

 

When you replace the exhaust gaskets don't buy the standard ones, get the Screamin' Eagle ones as they fit much better, at least that's what I found when I fitted my new Cobra pipes.
