Do a search on removing the cat from head pipe, it's not hard just takes some time. If your low on funds install head pipe after cat is removed along with the slip ons, this will get you by for a while. You have now removed a lot of the heat caused by the cat.Either now or when you have about $450.00 get you a Power Commander V along with a high flow air cleaner of your choice. This set up will get you by nicely, just remember do not change the aircleaner untill you install the Power Commander V. It's ok to install just the slip ons without the Power Commander.Any other questions call Fuel Motto they will be happy to get you taken care of.

Because it doesn't get all of the material, had a friend do this, then decide to cut it open. Was still lot's of material inside.

At no point do you "need" to buy an open ac. You can run slipons with or without a cat with no tuner. If you run slipons, no cat, and an open ac then you should get some type of fuel managment. Even Xieds or the adjustable Fl Vieds could richen things up. But if you want performance with the slipons, no cat headpipe, and open ac then you need a tuner. I am running a decatted headpipe, open ac, and slipons with just the (harley installed) stage 1 download and it runs great. I decatted my headpipe with a 1" paddle bit. Took about an hour and its 100% clean. No need to cut the headpipe to get the cat out.
My question always is, here, when folks say a bike runs great... is compared to what, exactly? The same bike, before a mod was done? pfft... nothing to compare there.
Go ride a professionally tuned bike and come back and say that.

This is simply WRONG! The exhaust on our bikes is THE bottleneck in the airflow. Open them up and you NEED some kind of tune or it will be WAY lean, but... what do I know?
