This might sound like a dumb one but here goes.

In reference to a Boarzilla

Is the inside "diameter" and "outside" diameter of the Boarzilla larger than the Fat Cat?

Also I'm assuming the Boarzilla's actual Header is longer in than the cat no?

While mounted on the Ultra C, will the Boarzilla setup look more bulkier than the cat's headers?

Please describe the differences in the two.

I received the Boarzilla yesterday, it looks the same as the cat, I'm fearing the possibility of D&D making a mistake with my order.

The difference is in the pipes I think.
The Borzilla has bigger dia pipes than the Fatcat.
Why they say to use on a bigger motor because of the velocity drop otherwise.
The muffler is probably about the same.
Only so much voluum to work with.
The more voluum the better really.

 

I think this is correct. If I'm not mistaken, the Fatcat header pipe starts at 1 7/8" and steps up, and the Boarzilla starts at 2" and steps up from there.

 

boarzilla is stepped 1 7/8's to two inch. Fatcat is 1 3/4 to 1 7/8's. On my dyna, by looking at it the muffler seems shorter. I don't have the Fatcat any longer so I can't compare. I'd have to say the headpipes on the Boarzilla must be slighly longer, not sure though.

 

yep, the boarzilla has longer headpipes, and a shorter muffler. Fatcat on top, boarzilla is the bottom pic.

 

I think the Boarzilla is for 117" and up motors because of the larger pipes. The one on my NT is swept up for ground clearance.

 

Thanks guys, I found my calipers, and a tape measure after I sent the initial post out this morning.

The boarzilla is stepped 1 7/8's to two inch. The Fatcat is 1 3/4 to 1 7/8's. The Boarzilla muffler is two inches shorter than the Cat, and the headpipes on the Boarzilla are about two inches longer than the Cat's headers.

I panicked, the Boarzilla muffler measured 27" the Cat's muffler measured 29" 27" would have been 2" too short. The extra 2" on the headpipe made up the difference.

Moving on!

 

You'll like the zilla. You get the standard baffle or the quiet one? I have the standard and it sounds really good especially when you get on it. Don't know what the neighbors think but I didn't buy it for them (LOL). Actually I ease through the neighborhood so as not to be too obnoxious, I do happen to like some of them.

 

I hope so, I liked the cat as well.

I bought wrapped baffle. Since I am in California, I have to practice a little restraint. I don't care to much about what the people next door think

The police are becomming a little bit more attentive these days.
