Bubs 2" Shotguns on FXRS with pics. : V-Twin Forum: Harley Davidson Forums

These also worked out great.

Early Dyna pipes from Bub's bolted directly onto my 85 FXRS.

Fit, finish, and mounting brackets from them are outstanding too.

Unfortunately I'm not too happy with how they sound though. They just kinda sound odd to me.
I was expecting them to be like the 1 3/4" drags I had on my Shovel but louder, being 2"... Not so.

They are plenty loud, but in a much deeper way than the super snappy, raspy, nasty sound of the 1 3/4"s.
But damn do they look nice.

Gonna swap them back out for the V&H Pro-Pipe and give that one a ride since I haven't actually run it yet.

If the V&H runs as good as they say the Bub's may be for sale.

Anyways heres a pic.

I dont know whats going on, but I cant see any pics here either.

Sorry man don't know what to say... Hey how do you like that EV 27? Looking at that one for my bike too.

Yeah I cant work it out, must be a glitch on my end somewhere. As far as the EV27 goes, it is fantastic, a very streetable cam compared to the stock cam, handles well from take off right through the gears. When I put it in , after running everything in of course, I took it out on the motorway and opened it up, and it scared the pants off me!! With the stock cam I was really pushing to get her up to 160kmh (100mph) but with the EV27 it shot up to 180kmh (112mph) before I realised and had to back off very quickly before I lost my licence!! Suffice to say I love it!! Not only did I get a bit better performance, my fuel economy went up as well, I used to only get about 230km before it hit reserve when touring, now I get about 245-248 or thereabouts. Not a great deal more but it all helps. The downside is, you do get a little bit more lifter noise, but it aint much, and you get used to it, I'm afraid there aint much you can do about it, its just because of the higher lift and more aggressive ramp. Hope this helps.

Thanks. Very good news.
Think I'll probably go with that one. If I don't get too crazy with the "top end job" this winter... Having visions of stroker flywheels though.

Well, choices choices...

Ran the hell out of the bike today with the Bub's, then came home and switched to the V&H Pro-Pipe.
After running them back to back my findings are this.

The V&H has the best bottom end of the three (V&H, Bub's, and the old Pythons) with a good mid-range, and lousy top end.
Sounds pretty good for a 2-1 also. Pretty loud with good tone.

The Bub's lost as little low end, but have about the same mid as the other two sets.
However they come alive on the upper mid-range, and flat out fly up top. Arm stretching top end pull.
Kind of an odd sounding set of pipes, but could easily be gotten used to.

All in all, my old Pythons (or Cycle Shack's...what ever they are) have the most even, all around performance of the three. And my favorite sound.

I just bolted these on and ran them. I think with some tuning there is more performance to be had from both sets.
The rear pipe on the Bub's turned gold for about 5" almost as soon as I started to ride it. Know that means something for A/F ratio's (but not sure which), and the V&H popped an snapped back a LOT meaning it wanted more fuel I think.

Once I decide which set to run for a while I'll start to really tune for it.

Too bad the local HD wants $250 for a dyno pull.

Discoloration on the pipe usually means heat, which means you're running a little rich. I usually go a little rich on my jetting anyway, which cuts down on the carb farts & tempermental warmups in the morning.

My Khrome Werks AR 2-into-2 tapered pipes aren't particularly great in any one way, but I like the traditional look, and the sound ain't half bad. And for $100 brand new from the factory, just a hard deal to beat. Had a Hooker 2-into-1 pipe that was loud as all get out, and ran pretty good, but always hated the sound & look.

Just go with what puts the biggest smile on yer face.

ripsass · 09-15-2009, 09:37 PM

Pretty sure hot means lean. Not rich.

Fartnokker · 09-15-2009, 10:58 PM

Hot heads (combustion chambers) causing detonation is from a lean condition. Blueing of your pipes, tho, comes from unburnt fuel igniting in the exhaust pipe.

From the Khromewerks website:

All chrome plated steel exhaust pipes or mufflers will "blue" or discolor when the surface temperature reaches 900°F. This can occur if the fuel mixture is too rich. Instead of the charge burning mostly in the combustion chamber, the mixture continues to burn after the exhaust valve opens, down the pipe, causing extreme heat and bluing of the metal and its plated surface in the most restrictive areas - most commonly the bends or the baffle area.

Glad to know about the early Dyna pipes fitting, tho. Gives me options!

ripsass · 09-16-2009, 02:39 AM

Good info. Thanks.

Seems that 91-05 Dyna pipes should be pretty easy to adapt (as long as the design isn't too wild) with minor bracket fabrication.
Great news for FXR owners.

Fartnokker · 09-16-2009, 08:29 PM

Hell, I had to fabricate a bracket to get my FXR pipes to fit my FXR!

I've read somewhere around here that Softail pipes will fit, with some bracket work, as well. Haven't tried it, though, but the Dyna seems like a closer match.

That does not surprise me, as people often buy the wrong year FXR pipes, I have seen it before as well a couplre of times. The early model (up to '86) FXR's and the '87 up FXR's use a completely different rear exhaust mount system and one will not fit the other without major mods to the rear bracket. I dont know if that was your problem, but, it is a common mistake.

ripsass · 09-17-2009, 12:43 PM

This is about using Dyna pipes on an FXR, so it's a given that the mounts will be a bit different.

Yes, but if you read carefully, you will see I was replying to Fartnokker who said he had trouble fitting FXR pipes on an FXR.

Fartnokker · 09-18-2009, 07:44 PM

I'm pretty sure those pipes were specified for all FXR. I called KhromeWerks about 'em at the time, and we discussed possible fitment issues. They didn't seem to think there'd be any.

For me, I was switching from a 2-into-1 exhaust that had different mounting brackets. I purchased a stock mounting bar that attaches the 2 mufflers to each other, then fabbed a bracket that attached the pipes to the tranny. Wasn't a huge deal. Nice to have shop facilities handy where it is easy to fab your own bits & pieces.
