anyone running white bros e series on big inch motor ?just wondering what you are running for disc count and noise level ,thanks pete
24 disks 124 snuf r not cap not loud at all
for noise level I wear ear plugs LOL
if I put the open end cap back on...
And if you are not satifisfied with the results PM me, I am looking for an Epipe for my '03 Ultra. :smilep:

El pendejo...is there really more than a red kunt hair's difference between an E pipe and a Supertrapp 2-1 Supermeg? Anybody ever check it out?
big difference in the muffler and core design, supertrapp falls short but then maybe not the e-pipe is long gone!

How and why does the supertrapp fall short?

Tony, I'll mention this to my son, Showdog75, he has 2-3 E-pipes for Touring bikes.

Thank you Mike. PM me if something comes along.

hotrodking: are you using a mountain core or standard?

I got one of those mountain cores hanging around -unused
Whats so great about the E pipe? Friend has one on a Built 103 bagger w/ ported heads and woods 9B HPImc 51 TB only does 107HP 110TQ nothing special. Its sure not Quiet. Newer designed stepped pipes like the RoadRage or Fatcat better performance.
i have a moutain core as well if anybody needs one.

Well my experience is different from your friends. My pipes are for dyna so I can't speak from actual experience on bagger versions.
I have a WB e-pipe...two actually. I also have a Bassani Road Rage and a Fatcat as well as CS tapered 2-2 with 2" stepped headers. With the e-pipe you need to have a mountain core and open end cap on higher hp/cu in builds to max performance and you need to work the combo's. On my 95" the e-pipe was best overall...and way less loud.
I am going to run all the pipes on my 107 (target 125/125) which is going together and I expect the same results.
<<i have a moutain core as well if anybody needs one.>>
is it from a bagger pipe or dyna/softail?
EJ arent there 2-3 diffrent designs for a e-pipe.
one for dyna and softtail with forward controls
one for softtails with floor boards
one for baggers.
performance will vary with these pipes as the dyna softail pipe is the real good one where the pipe wraps around the cam cover.
thye bagger pipes may be a bit too long aand the floor board one for softtails is not a good performance pipe at all.
Steve from GMR hasd one of these pipes on his bike with a 124 in it. the softtail dyna pipe for forward controls

the cores are different from model to model? Its for FXR/Dyna
the core has nothing to do with different model bikes. mountain core or standard core fit all mufflers for all model bikes. mountain core has an elliptial outlet and standard core has a smaller round outlet. i'm running a hooker stepped big inch headder tubes with the wb e series muffler. seems to work real well. is a tad on the loud side.
I will have got a E series for a bagger for sale
<<the cores are different from model to model? Its for FXR/Dyna>>
not model to model. just baggers vs dyna/softail
<<the core has nothing to do with different model bikes. mountain core or standard core fit all mufflers for all model bikes.>>
based on your comment i would guess you have not worked with the bagger vs dyna e-pipes. although the core themselves are the same size the mounting holes are located in completely different locations for the bagger pipe vs dyna/softail. i have worked with them both and have had to modify the mounting points when i could not get the right one.
<<Its for FXR/Dyna>>
i am interested in the core. i will pm you.
<<I have a WB e-pipe...two actually. I also have a Bassani Road Rage and a Fatcat as well as CS tapered 2-2 with 2" stepped headers. >>
don't get me wrong they are all great pipes. the fatcat and road rage look and sound better than the e-pipe and perform great. that's why i keep them all.
<<EJ arent there 2-3 diffrent designs for a e-pipe. >>
yes this is the good one...also shows mountain core vs std core -

this version was available for both dyna and softail. i don't think it is a coincidence that the rear header configuration wrapping around cam cover is also used by the road rage and r&b best performing lsr pipe.
Quote[/How and why does the supertrapp fall short? quote]
sorry to answer late but what I found is a lot more volume in the e-pipe muffler and there core entrance is funnel shaped producing a reverse megaphone effect
What is a reverse megaphone effect?
ejk_dyna
Based on what you wrote I have a standard core for a Dyna if you ever need one.
I bought it just to have an extra for my Bagger and of course it doesn't fit.

Interesting to note the difference in length between the front and rear primary pipes. In some cases just the opposite from other pipes such as the Propipe where the rear is much shorter than the front.
It's also worth mentioning that it appears from testing the difference in primary length can be as much a 6" without affecting peak performance, however it does affect low rpm reversion.....some better than others.
JME,
Bob
PS question: Since it is universally agreed the E-pipe is/was a winner, why has no other pipe mfg simply copied the design (pretty easy to mfg) and marketed it as an E-replacement exhaust?
Wish there was an exhaust mfg on here to address why they haven't done it.
Note how close the Thunderheader primary pipe lengths are compared to the E-pipe:
(http://i449.photobucket.com/albums/qq211/spdcomp/Thunderheader.jpg)
that curved header only fit a few bikes.
My Heritage E is different, in fact I think I'll put it back on over the
bassanni pro streets
don't wanna be called a fag
rmmrmrmrmmmrmmrrmrmrmrmm!
The odd fire sequence of a 45* V-Twin presents some interesting challenges for tuning, even more so when the exhaust is 2:1 is combined with a common plenum, short runner intake manifold. In some cases the unequal length header pipes can aide in power production, sometimes they don't. Same holds true for equal length header pipes when used in 2:1 setups. Cam timing plays a big role here, as well as flow characteristics of the heads. Much tougher to make a one size fits all, off the shelf solution for these critters than other engine types.
Join the "Pipe of the Month Club" ... I hear they give out discount coupons. :>)
FWIW, I used "cut and try" a lot more when building exhaust systems for HD's than I usually do for other engine types.

FWIW, we've found the Propipe to be more prone to low rpm reversion than other pipes with more equal-length primaries.
Bob would that be the bagger pro pipe or the pro pipe in general???
i have the wrap around cam cover style on my dyna ,the long one on bagger and have put the one for floorboard bike on a build i diid for a freind that works very well also ,the bike i was concerned with when i started this post is getting tuned now and was up to 37 disc on friday have not heard if anymore was put on since so i will have to wait and see how loud it is maybe i will need a amp for stereo .thanks pete

Ahh, so we have a long divergent cone connected to a short convergent cone 'cause ya know folks, we can't do this expansion all day and at some point we have to stop the madness... :smiled:
just saw brand new e-serias for softail with mountain core and heat shields on ebay, never been used , just thought i would let you know , i would try but with the rr cam plate dont think it would fit

Bob its long been my thoughts that the mfg has found there is more money in the "look at my big tit chopper pipes" . I bothered my drag rep all the time since the White bros exhaust are now made by Burly brand and I could have swore he told me they are owned by Drag / Lemans corp I could be wrong though, he's retired now but I'll try remember to give him a call .
tmwmoose ,vance and hines owns the rights t white brothers they are now making 4 wheeler pipes and v&h rep told me in laconia that were going to start making pipes for bikes ,we'll have to wait and see if that really happens or not ,thanks pete

Bagger Propipe. The dyna/FXR isn't as bad. Kinda same as the Fatcat is different beteen the touring bike vs Dyna.

Sorry fuzznut I didn't mean to ignore you Ive just been running around today. I'm not the one qualified to explain this tuning scenario I just know its been around for a long time and was used a lot on dirt track bikes. if you saw a cutaway of the e-pipe muffler you see the long expanding megaphone and then the entrance to the muffler core tapers it down its like one long funnel with a super short one on its end and it all has to do with exhaust pulse tuning well there ya go I said I wasn't qualified but that didn't stop me from opening my big mouth now did it! what I should have said this is better answered by the motor chef's here!!

You mean a reverse cone like the Thunderheader?
(http://i449.photobucket.com/albums/qq211/spdcomp/Thunderheader.jpg)
R&B Racing LSR B Style which they say is their best performing header
(http://img97.imageshack.us/img97/3707/lsrb.jpg)
Bassani Road Rage same concept on rear header pipe.
(http://img200.imageshack.us/img200/8964/roadrage.jpg)
...so e-pipe, road rage, lsr, t header all have similar rear head pipe configuration...seems to work pretty well.

ejk_dyna i have a mountain core that you can mount in any can. all mounting holes are threaded. i have a standard that core that mounts one o'clock and six o'clock looking in the outlet and a standard that mounts eleven o'clock and five o'clock. that must be the difference you're talking about between models. just curious
Steve at GMR used to run an E-Pipe on his 124" Deuce before he sold it. Maybe he can help you out.

Fuzznut,
What pipe is that in your pic?
definitely WB head pipes
