Define inexpensive.
Staintune mufflers cost OZ$1200 a pair.
Keihen, in SS, are very similar, and cost half that. For noise, Keihen make a set designed by the UK BMW tuner, Jim Cray. They're good....reminiscent of the sound from a BSA Goldstar I'm told.

has Norton mufflers, both cheap and better ones that are not so cheap...and the supplier has a good reputation
FWIW the Triumph T140 pipes they sell might work too, and sound great on a Triumph

They look flash and not to expensive either! How do they mount? I'd wager they're LOUD!

These are really decent pipes- keep in mind you'll need to have them expanded from 36mm to 38mm to fit over the headers. It took me awhile to track down an exhaust shop that had an adapter small enough to do that. nice and loud.

Take a look farther down the page. The "big bore" ones are for 1 1/2" headers which works out to 38.1mm

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...

Really.

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!

Something tells me that'll be L-O-U-D. I'm making a 2-1 with a big one of those.

Hey alister, can't quite tell what sort of flat slides you've got there?
