     Crux |
Currently I have a stock exhaust on the '00 X1, wrapped. Looks good, however the race module is going on soon and I need a new can for sure. The stock can feels like a block of lead on the bottom of the bike and needs to go...plus, it doesn't sound mannish enough for a stud like me. My question is, I realize the race exhaust makes the bend and no elbow is needed, but is there any other differences? If there's not I can't figure out why I would need one as D&D, Supertrapp, Etc. all make cans for both. With that said, any expertise in the matter would be appreciated...I need a new exhaust one way or another, and I want to get it done asap. Thanks fellahs...(This is the greatest forum ever) | ||

Al Lighton pretty much answers your question in the XB exhaust shootout report. Longer pipes evidently help spread out the power peak over a wider RPM range. It would be interesting to see how much difference there is between the race header and stock with aftermarket cans. BTW, Kevin Drum can make a Drummer for your tuber if you're interested. He's doing one for my S3 at present. | ||

If you want pulling power right off of idle then you need the race header. I've spent money on some good mod's and not so good mod's, but that was money I'd spend all over again. It makes every thing else work better...........Charlie | ||
| Crux |
but what is the difference between the race header and the stock?...I mean with the elbow its only and inch or two difference, unless there's something else that the race header has that I'm not aware of... | ||

For all out sound, D&D all the way. But, D&D is basically a straight thru muffler...so, of course it flows.... But, if you also wanna smooth that power band out, you need the race header, or the D&D full race system.. All in all, the best bang fo rthe buck, I THINK, is the full D&D system... Anyway....

Are V&H cans straight through too? My friend's M2 sounds like more of a low rumble with its V&H. I wouldn't suggest getting one of those since you have to take the muffler off to drain the tranny fluid. (still sounds nice though.) Another option is to modify the stock muffler. It's mild steel so if you can weld, you can open it up and alter its innards. | ||

I, for one, didn't feel a huge improvement with the race header on my M2. Granted, my M2 was already rejetted and had a V&H can on it to begin with, so maybe that's why it wasn't a night and day difference. Also, M2's aren't tuned for power, they're tuned for midrange; maybe that's another reason why it didn't make much of a difference (that I could feel). Surprisingly, it did make a difference in the exhaust note (what I can hear of it from the saddle). It's hard to explain, but at low rpm the exhaust pulses do indeed feel more "separated". I'm sure X1's benefit more from the race header. | ||

I like the D&D, but what I'm trying to figure out is what the difference is between the two headers....is the race a bigger diameter?...b/c other than the elbow I cant find a difference between the two. | ||
| Whodom |
Crux, The tubes on the race header are longer than the tubes on the standard header (more distance from heads to collector). It's not a huge amount of difference, but that extra length does make a difference. That gives it a broader power band. | ||

Ty sir. | ||

Race header exhaust runs are about 9-10" longer than a stock pipe. This is from and S1. Brad  | ||
| Crux |
10-4...yeah I understand that, but with the elbow included I cant imagine the exhaust is more than 4-5 inches longer, I guess people see a difference though. I'm just torn as to spend the extra money or not on the race. | ||
| Chasespeed |
On the X1, YES, it makes a seriouisly noticeable difference... I dont know how many race headers are available out there... I just sold mine, witha D&D slip-on to Prez, hopefully he will get it on here soon... Anyway, if you arer grabbin gall this new, you might wann alook into a Full exhuast system...there D&D is like 616 , and the Force is 7something... Chase | ||

I have the stock header and have had the supertrapp and D&D. The D&D has MUCH more grunt and power than the Supertrap. It is also MUCH MUCH louder. But me likes it. I have the force intake and race ECM and can pop a wheelie in 2nd gear w/o any problems (ask Jugs and Hardcorps, they saw me pop one @ Frankenmuth a couple weekends ago). If you are unsure about spending the dough on a race header.. the D&D is a 2 peice muffler w/ the elbow being seperate so if you do get the race header you don't need to get a new muffler. you can just put it on and remove the elbow from the muffler and VIOLA! which ever you do enjoy | ||

Crux, just food for thought. I have been using the stock header on my 2002 M2 with a straight thru 2 1\2 inch car muffler but recently bought a CarChemistry (www.carchemistry.com) insert to quiet it down a little from their auto section and found a good improvment in low and mid-range pull, as they claim, with little or no noticeable loss of top end. Pulls hard to redline. I have a race ignition module and K&N ham can air cleaner and jetted properly for my elevation (4200')which is still 45 pilot and 195 main. Sound is still throaty but not objectionable. Check out their website for more info. Bob | ||

Bob, What cams are you running in your cyclone? Thanks Charlie | ||
| Bob_thompson |
Charlie, stock M2 cams. Love the low speed grunt and with my setup pulls strong to 6800 rpm. | ||

I would reccommend the D&D SLip on for the bang AND the buck I've hear several others on Buells and like the sound of the DD the best, I rumbles more and does not crackle as much, FOrce full exhaust crackles and pops to much for me, the DD Sounds smooth and loud throughout, From Idle you know it's a harley V-twin, and when you get on it, heads turn, IMO The extra cost of the header is more than I need, You can spend the extra on jet coat for the stock one and it will look good and run cooler, I got my DD for around 250 ANB | ||

As an update to my last post I just received the new Summit catalog and they show a nice 14 inch long by 2 1/2 inch straight thru high polished SS muffler by MagnaFlow for just $63.95. This and the CarChemistry insert will be my next muffler if I ever need one. Why pay the high price for a "motorcycle" muffler when these can work marvelously and look good too for a fraction of the cost. Just my $.02 worth. Bob | ||
| Natexlh1000 |
wow! that is a good deal. Do they have elbows of the correct type to adapt to a standard header? | ||
| Djkaplan |
SS mufflers are awfully heavy. I didn't use the SS race muffler with my race header because it weighed more than twice as much as the V&H I was using with the stock header. | ||

The race header removes the dip in the torque curve at mid-rpm. Huge differince in tractability and control at mid-corner acceleration. Race header is well worth the investment. I have the Buell race muffler as well -- it's been 100% more reliable than Supertrapp or V&H, but it requires frequent re-packs. The D&D sounds like it might be a good alternative. | ||
| Bob_thompson |
Nate, yes and no on the elbows. I bought a preformed elbow (2 1/2") that I believe had the correct radius (6" I think) but had to cut down to the right length and weld to the header and was slip on (in) to the muffler. I think this is very similar to the race header as I believe it from talk here although the primaries are a little longer on the race header and it ends after the curve like what I have now. The longer primaries are supposed to enhance midrange which I accomplished with the insert. I also used a spring mounting system to alleviate the breaking of header head studs and muffler mounts. See my post in KV under: broken muffler mounts fix in Engine, Exhaust: header, mufflers from 08-05-05. All this was less than $100. Djk: my Summit muffler seems to be about the same weight as the stocker but if it weighs any more its way down low where it doesn't effect handling and the performance increase, I believe, more than overcomes that. | ||

"my Summit muffler seems to be about the same weight as the stocker but if it weighs any more its way down low where it doesn't effect handling and the performance increase, I believe, more than overcomes that." My concern wasn't how the weight would affect handling, my concern was how the weight contributed to the Pro Series front mount failures on the race header. The race header is much more prone to breakage than the stock header on your bike. I never had a problem with the old V&H and it's significantly lighter than the race muffler, so I cut off the elbow, trimmed the can 2", and repacked it. A muffler shop enlarged the inlet for free - thanks Meineke muffler on Veterans Pkwy! I drilled offset mounting holes in the original V&H rear hanger and everything lined up perfectly. The the rear mount bottoms the inlet to the collector so the muffler can't work it's way off. So far, my race header/V&H muffler hybrid exhaust is working really well, but time will tell if the weight reduction will keep the Pro Series front mount from breaking. | ||

Here is the mount I am talking about. It's clamped onto the collector on the race header  | ||

Dan, I really like your mounting system as you have described it and it seems to be working but I am wondering if there is any vibration canceling ability in your setup. I seem to have found that the system I'm using does just that because every so often I have to replace one of my springs that just breaks at the hanger(top) end. Kind of a sacrificial lamb if you will. These are two for about three dollars at Home Depot and ten minutes to change. They also hold the muffler very secure. |
