well there you have it!
I have Staintune sport mufflers on my bike now although I wouldn't recommend them. I usually roll my own. Use an original first cone from stock mufflers. They are often in good shape on rusted out mufflers and too much trouble to fab any better. 60 degree reverse cone with two inch inserts welded to another 60 degree reverse cone with an outside cone welded to that. They're loud but a lot quieter than open reverse cones. The cupped inserts are a lot quieter than inserts with just holes but they cost you a bit more on top. You pretty much have to run packing with perforated inserts or they are entirely too loud IMO.
Just use a jiggle saw and cut the muffler off. Sounds just as good as any of the loud mufflers that are made for BMW's
Those mufflers are only put there by the man to trample on your rights. Free your noise...
You know, loud pipes save lives and all.
Just remember that the vast majority of the public, they don't ride. and they don't like loud bikes and some of them even vote.
Loud pipes would save more lives if they pointed forwards. They will help you from getting rear ended more than anything. The cruiser guys need that feature around here in the SF Bay area. I still can't understand how motorcycles can hold up old ladies and log trucks on a curvy mountain road but they do all the time around here. Usually, the louder the pipes are the more traffic they back up. I would be afraid of getting rear ended too if I rode that slow!
I'm going with the cone engineering pipes- had an 11" mid-pipe welded up, they feel very well made. Haven't even gotten to hear them yet! will let you know...
Something tells me that'll be L-O-U-D. I'm making a 2-1 with a big one of those.
Nice! for the hpn or the ducati? Would be sweet on the duc...
Yep, they'll be LOUD
Hey alister, can't quite tell what sort of flat slides you've got there?
They're mikuni tm 38's- gas hogs but excellent throttle response!
It's going on the beemer, I have one of these coming for the duc:
Those are going to be two HOT twins. very jealous.
Friend of mine has the Cone's on his R65. He has a video up on Youtube do a search.
I just slash cut my stock mufflers they were so beat up. I like the way they came out and they really are not that loud. There actually still a baffle inside them. Best part about the mod? It was free except for my time...
You can hear it here. Me abusing her on the burnup board.
I have an old Luftmesiter 2 into 1 on my R100RS "Das Beast". Also had the same on my first BMW 30 years ago on my 1977 R75/7.
You can pull the baffle out easily and wrap it for under $7 US... and get the sound you want.
Mine is pretty beat, but still all there. I will probably have them "Jet Hot" coated black come winter.
As a rule, BMW Riders hate them... so you can pick 'em up dirt cheap at swap meets, and the other online places.
+1 on the freebies. Milestones, you said you wanted "relatively inexpensive". How about "cheap"? I like my chop saw.
A friend of mine claims that he has never seen an exhaust system that he couldn't improve with a hacksaw. He runs the first cone of /5 mufflers (slightly larger diameter than the later ones) hacked off at the first seam with nothing inside. When he starts his bike he proclaims that he is going to "ring my bells". They are louder than a mofo! I have listened to them inside of his slip stream at 100mph. It reminded me of a lot of the soundtrack to the movie "Lemans". Loud engines at high rpm. When he wanted to slip by some cops undetected he could reach back and put his boots in them for a mile or so before his feet got too hot. Night and day difference!
+ 1 . Give me my hacksaw, hole saws, drill bits, sawzall, chisels, punch, and chop saw. I have opened up many stock exhaust cans (and air boxes, too) in many ways on many machines. ( too many "many's"?) Gotta let 'em BREATHE.
I stacked supertrapps. They DO NOTHING for the old style look, but they sound tough.
^^^ Those look great on there! love to see the whole bike...
