Decat Pipes
#11
In my opinion, what you guys are doing is merely drilling a hole in the cat material. Having cut a panel out of my cat, I dont see any way at all that you have all the material out, not even close. With my panel removed, I had to chip, tear, scrap and grind ALL of the material out so that when I had the panel welded back up the surface was devoid of any little strips of the metal catalyctic material. I could imagin that leaving so much material that you would be leaving "could" possibly cause metal on metal tinny sounds as the exhaust pulses through the chamber.
Just my 2 pennies worth. Do as you want to your bikes.

Hey JD I have a stage 1 screaming eagle breather $ 140.00 29260-08 and a Vance & Hines Skullcap insert $ 50.00 jp cycle part #404-538 pretty nice setup and it will get ya started if ya want um I'll take $85.00 shipped,and no you won't have to get a tuner for your bike.getting rid of the cat is the best thing you can do for your motor you won't believe the difference in the heat. Good Luck

I also decatted my own head pipe and I don't think a hole saw will get all the material out either. Even with a window cut it took some effort to remove all of it...
Slip-on's and a flowing head pipe shouldn't need a fuel management system. But all bikes are different. You will enjoy less heat and more of a rumble with just the stock slip-on's.

yep, getting rid of the cat will do nothing for performance or heat (while you're riding). Look at it, it's below and behind your feet, how can you get ANY extra heat when riding??Air flow will move the heat back behind you, right?
I can't feel it at all (2011 FLHP) but I wear boots and long pants; if you're gonna wear flip- flops and shorts, ANY bike is gonna roast you. Just sayin' :-)

huh??
The cat in the very instance of its design and intention is to get so hot that it burns off any excess fuel not burned in the combustion process, getting rid of that material, whether by taking it out of the stock headpipe of an aftermarket hadpipe will reduce heat.

Trust the ones that did it with the paddle bit. It removes everything. Until you do it you will never agree i guess. Probably even with a pic you wont agree.

Do you feel heat from the cat in your car?? How can you feel it when riding your bike, it's behind and beneath you. When you ride the airflow blows all the hot air backwards, right??

Airflow does blow much of the heat behind you when cruising, however passengers get some of this hot air on their right foot.
When you slow, have a tailwind, or stop the heat gets pretty down right annoying. Getting rid of the cat gets rid of most of the heat.
GF had a pretty rosie red ankle when city riding on our catted bike. She is much, much happier now.
Without the cats, I am now free'd up to add some Vied's to reduce the lean stock condition, The slightly louder pipes make the bike feel better too.
