If you are just changing the exhaust you should not have to do any other modification to the tuning. If you change the breather then you need tuning.

 

The cat needs to go.

 

 

There are several active threads on this very subject...take a look around them so you can be 'even more confused',

 

Sounds OK to me! At this stage just take American Custom's advice and fit them to see how they work. If you find your bike doesn't run as you want it to, come back and we can talk through what to do next. I certainly wouldn't buy anything else just yet.

 

As many, many owners have found, the xied things generally just add to the expense of the final answer. They simply add fuel across the board...some cells may already be too rich and would benefit from a reduction in fuel.

These and similar devices trick the system into thinking the system is running too lean and that's generally not the case. There are several tables within the tuning spectrum that can have a significant affect on perceived heat. Incorrect timing can result in much greater heat generation then an AFR setting. And the xied's do nothing to address that issue.

While I fully understand the desire to save money, getting the ECM set correctly from the start will save you money in the long run...and you might actually be happier with the way the bike starts, idles, and runs. Even a bone stock straight-from-the-factory bike will normally benefit from a proper tune.

Good luck!

 

 

I've run XiEDS on my last two bikes. They install in about 5 minutes, give or take, and they've worked very well for me.If you can plug in a lamp, you can install these easily. Simple solution for cooling your bike down by adding a little fuel. You can find them on the internet for less than $100. For your situation, I think they would work fine. I feel like you, I spent a lot of $$$$ on previous bikes for tuners, dyno runs, etc., and I wasn't impressed with the results for the money. Of course, I didn't go past a simple Stage ! and on my last two bikes I only added slip ons and XiEDs, with the stock airbox. If that's all you're doing to your bike, I recommend them, though others may say different. As for me, I think they do a great job for what they are. My bike runs just as well as my older bikes with expensive tuners, etc. Of course, I'm older and just like to cruise at normal speeds.

 

I understand your thoughts but I would highly recommend getting rid of the cat. That can be done for next to nothing and a dynojet pcv will run you $299.00. Do those couple things and you will be a lot happier with your bike.
