08 FXDF Fatbob. I ran a Propipe and Sideshots and neither broke. The E series is a stepped pipe and flows well without making too much noise. I can play around more without attracting the attention of the law.
Go for the wrapped baffle and it sounds great. I have em both on my LRS and Bagger, Id hardly call em obnoxiously loud.
Id guess the others you heard were the perforated baffle. Alot of guys with M8s get the loud baffle in hopes of getting the TC sound from a M8.
Keep in mind alot of D&D cans contact the axle bolt with extended shocks. My Bobcat can lightly touches the can with 13.5 shocks on full extension. Just fyi.
Come on... You CANT possible think ANY sound you hear out of a PC speaker/YouTube video is going to come close to realistic sound levels. Heres something to think about. When you record something using your phone (like 99.9999% of YouTube videos are) the phone sets the audio level automatically. It tries to make everything it hears the same volume level. So its a fools errand to think you can judge the volume of a pipe from a YouTube video.
Maybe you can get some idea of the tone, but even that will change with the volume relative to how close you are.
Go to any bike event and listen to pipes first hand, thats the only way to realistically hear how loud a pipe is.
As an example, go find Matt Laidlaws exhaust comparison video. Youll hear a dozen pipes, and even the stock pipes sound pretty much as loud as the D&D he has (maybe with less clipping) because the levels are all boosted/lowered to match what the camera thinks it should be.
All that said, I had a fat cat on a M8 Softail with a cam, and it was fn loud. I never heard a twin cam, but I understand they are louder. I would love one on my worked LRS, but now that Im in Florida, I dont want to get shot at by the neighbors...
No, no. I don't think that. I know good and well that microphones via either a phone or a camcorder or such can't anywhere compare to hearing it in person!
I would definitely love to go to more bike events but lack of lots of vacation and the closest one being 4.5-5hrs away, kinda limits me. Priorities though, I know. And everybody around here for the most part is V&H, Thunderheader, or SE pipes. Maybe some Bassani's and Rineharts every now and then. Never seen/heard a Fat Cat in person.
Laidlaw does do some good videos overall. I've have to find it and check it out. Thanks for the heads up on that aspect.
I bet that M8 sounded good though at least! TC's are louder? Wonder why...Yeah, definitely getting shot at would ruin a good day pretty quick. Have any plate carriers? Haha
Yes seriously... They tried to blame it on me and the bike was always garage kept.. I'm an **** m***********..
And Mchad is right.. You need to go to an event to listen to these things to get an honest opinion.. the real key though too a good sounding pipe is compression..
That's a bunch of crap!! But on the flip side, I'm sure they get a lot owner error trying to blame it on them and trying to get a free pipe out of it as well. I see both sides. They don't know all their customers personally, so they have to judge on the situation. I'm not saying it's fair either, but, you get what I'm saying.
I agree, I do. But here in VA, it's getting ready to be winter.
Thanks for that. I think I like the D&D better honestly...a little bit. Sounds more...Harley-ish? That's not the right description. More muscle-y maybe? Hell, I don't know. Haha
I have a Supertrapp that I run on my Evo as well. I like to change things out from time to time. Quality is very good probably not as good as D&D but it is very good.. One of the best things I like about the supertrap pipe is the collector.. It's more streamlined than most other pipes out there which works very well when you're into the higher rpm ranges. But the nice thing about it is that you can also tune it for low end.. It's one of the most versatile pipes out there for the cost.. I think I paid $675... I ended up taking all of my discs and open end cap off and I just run it wide open and it sounds excellent... In the picture below there's a Kirker on the bottom a Supertrapp in the middle and the D&D on the top. If you look at the collector between the D&D and the super trap you'll see how the super trap is more streamlined than the D&D. This is why the D&D has pretty good numbers for torque but yet still breaths very well up top. They offer two baffles with the D&D perforated which is very loud or louvered which is still loud but better for all around street performance.. The Kirker pipe is not tunable even though it's identical to the Supertrapp in design it just comes with a trimmed wide open end with a perforated baffle. They are very loud and very good over 3000 RPM. I hope to put my supertrap back on before the weekend is out and if you want I can send you a video clip of it. If you think that on the supertrap the pipes are too blue because it's too lean it's not.. I run my motors 13.8 to 14.1 AFR's because lean is mean..
WOW! Those are all very close to each other. Thanks for the comparison and the info. If you ever got video of it, by all means, go ahead and send it if you don't mind. It'd be appreciated!
From his first post it looks like a 13 Fat Bob, so should be.
A shop I know recommended against Fat Cats on Dynas. Said they saw a number of head pipes cracking from the vibration. Dont really get that, as the bracket mounts to the transmission, which of course is bolted to the motor, making the entire setup effectively one piece. The Fat Cat is big, maybe the trans bracket flexes a little too much putting stress on the pipe? Dont know the answer to that though.
The one I had on a Softail was very solid (well built) - I would still probably get one for my Dyna. Wish I could hear the volume of it with my mods. I like loud, but not ear bleedingly so. The M8 Fat Cat was loud indeed, but M8s are so different exhaust sound wise, its comparing apples to oranges...
Well damn. That would suck. Every part you buy is going to have some defects here and there. Nothing is PERFECT. What makes the difference is the customer service and how the treat you. Not that I'd be happy if that happened with mine, but don't they offer a warranty against craftsmanship/defects? As big of a company as they are, you'd think they would. I'm with you on the flexing and "one piece" theory.

How did you like the Propipe? I'll look at the E-series too while I'm at it.
