    Default Gonna Gut my catalytic converter

    Ok guys I am looking for some advice. I am going to gut my cat but leave the mufflers stock. What is that going to do to my computer? Will I need to get it reprogramed or replaced? I am trying to get rid of some of the heat and maybe gain a little performance.

    I bet you will be just fine doing nothing. I need the same thing to my neighbors 13 TRI without any negative side effects. The piper is cooler and the mufflers are slightly more rumble. The stock ecm flash adapted to the slight change.

    You should be fine. Probably run a lot cooler too.

    As has been said, you should be fine. But I'm assuming you have a Stage 1 ECM flash. Really not sure if you don't. Might make it run very lean. But regardless, you can certainly take advantage going catless if you did have a fuel controller.

    better yet remove the cat with a 1 x 16 inch paddle bit. drill it out, go slow it's easy to do. $10 at lowes hardware. you can get it all out, there are some that say you can't but i've always got them clean as could be with the drilling method.

    I lucked up and found a complete exhaust system on Craigslist for $30. My ride will not have to be down long. I am going to gut this cat then put it on then I may gut the one on the trike for sale.

    You might notice a small increase in the sound ... deeper
