Haven't gotten around to that yet. I have a v-rod thunderheader (2" twisted primaries and larger muffler) I'll be using for parts to build a custom thunderheader. I have tubing to make it stepped 1-3/4 to 1-7/8 to 2" and I had a collector made by burns stainless. I only picked up the boarzilla to compare my current and custom pipe against a known good off the shelf pipe. Either way the boarzilla will not be staying on the bike. It's too long, low, heavy and ugly and just doesn't sound the same. I've been too busy riding and enjoying the bike and buying a house/shop to have time to concentrate on building the pipe. It's running pretty strong now but I'm sure I'll get bored mid season and work on the pipe. Are you interested in trying the boarzilla when I'm done with it?

Threw the zilla on this morning and did a couple edits on the tune. Very disappointed with the sound, it's very quiet. I'm guessing this baffle is wrapped but I didn't have time to pull it out. Didn't bother making a video with the way it sounds right now. It's a hell of a sleeper for now. Could easily be passed off as an everyday big bore and cams, one would be sadly mistaken.
Here's how they stack up. Green thunderheader blue zilla. The thunderheader felt angrier at part throttle, zilla goes like hell over 4500. Went 148.8/133 std.

Looks like that Boarzilla has a distant advantage from 2700 - 3400 rpms too. Man it must be a bitch to put up with that 137hp and 128tq on those thunderheaders! 
Kinda problem I'd like to have!

wow what a difference in the performance must really feel the difference at 4500 rpms gotta feel like you added some more cubes to her. or if the bike had nos and was just touched off. for the gain its its diffidently worth keeping the boarzilla on. but I personally know what the TH sounds like and its unique on a HOTROD setup. yours diffidently is a bike with attitude!!!!! with what ever exhaust you choose to run.
