I'm a new owner of a 2013 judge and wanted to experiment with some slip on muffler with tips to replace the stock muffs. I have read a ton and can't find what the stock mufflers inlet size is? Magnaflow and a ton of others have nice 3.5-4" round stainless and Black powder coated mufflers with killer tips on them. As much as a pain it seems to be to get the stock muffs off I wanted to have them on hand during surgery. Any help?

2" or 2.25" ?

So it seems it's either one of the two (2" or 2.25"). The cross roads is 2.25" but not sure on the Vegas/kingpin/judge. Anyone? I will post pics and a video when done. I want to keep the merging chamber for best performance in lieu of changing the headers.

wowza!

Amazing amount of support! THX!
The inlets are 1.75". For those looking their are many adapters Walker 41886 will reduce a 2.25" muffler (using the Magnaflow polished stainless muffler with tip, she is 14" long / 4" round) to fit over the 1.75" header. Will post results when done.

Bitwell Mini Muffler

I found something new that fits/bolts directly on the 1.75" header pipe. These are called the Bitwell Mini Mufflers. I ordered the Black "Grenades" which are 10.25" long and 2 2/8" in diameter. This will give a kool look to the Judge. I will post a video and pics when done.

lots of fitments but

you can slip on anything that fits but may need to improvise a support bracket. i am partial to 304 stainless + dimecitycycle.com has them with brushed finish at lo prices, prolly made by cone engineering. i would like a lighter muffler with a merge collector for my 13 hammer keeping the benefits of a 2-1 system. one slip-on can save some lbs

You're welcome. Maybe sometimes people just don't know so should they tell you a lie so you think you're getting support?

1.75" confirmed

Well as told by d&d it is 1.75" in diameter for the inlet. I test fitted the magnaflow tips and they looked ok. They were too long for my taste. I will post pictures tonight. I am excited about getting the biltwell grenade pipes and seeing how they look/sound/perform. After removing the cats and Debaffling the pipes completely she sounds much better. Removing the cats help tremendously in the tone. I will get the tune updated this week too.

Since you have done a decat you definitely need to get on the tuning. The cats are an integral tuning part on a Vic so anything you do to them will degrade actual performance at reasonable RPMs. You may recover some of it with a tuner.

A lot of opinions on that subject. All aftermarket exhausts besides Vic's lose the cats to maximize flow. Disconnecting the 02's, high flow filter combined with decat/debaffle has an excellent feel and much smoother power with a noticeable top side increase (butt dyno), not to mention less backfiring. I will update the tune and advise with the addition of the biltwell mini muffs too.

I think the steel frame bikes run better without the cat, but keep in mind your bike is very lean stock and with the filter-decat-debaffle you are dangerous lean. You have to put a fueller on your bike. Do not pay for the dealer to flash it as it will still be too lean. Use the money to buy a used vfc 3. Cheap and you can tune it yourself as you make changes.
