How do you get the cats out of the header pipes on a 2010 street glide?

 

buy a Fuel Moto one!!!

 

What he said!!

You can cut 'n' weld, or hack 'em out, but bear in mind you may wanna save that header for future tests..

 

the Fullsac headpipe is also very good!
but the best way to remove the cat from the stock headpipe is to cut it in half, scrape out the cat and weld it back together.

 

Will it require a ECU change or will I be okay unless I change the air filter.

 

the bike is setup to run lean in stock form, changing the air filter alone shouldn't make it run much leaner... but changing the air cleaner AND the exhaust WILL make it run alot leaner!

it's an air cooled motor, so anything you can do to make that thing run cooler should be a big help.
after you remove the CAT, you should use a tuner to help make the bike run cooler, aftermarket tuning software WILL not only make it run cooler, but will also give you some more power.

the TTS MasterTune is tuning software.. it requires NO computer change.

 

Be forewarned... I removed the cat, rotozip w/fiber wheel, air hammer with chisel bit (metal is damn near 1/4" thick there) and a welder. Had it out and welded back up by a buddy in no time. Soon after I installed 255 cams. With the increased duration or whatever it was, around 2800 rpm it sounded like someone was playing drums on the motor with carpenters hammers.

Turns out it was the chamber the CAT was in resonating. Annoying as hell. Sounded wicked unless you were on it in that rpm range.

My .02 cents.

 

Cut it in half at either one of the welds. An air chisel will get the cat out. Weld it back up. Done.

 

Send it to fullsac (www.fullsac.com) About 100 bucks and they specialize in this.

 

You can also do as I did, got the V&H Power Dual headpipes, love them and I think they look good as well.
