SL350 muffler options

LashLarue · 04-19-2010, 08:57 PM

NOS mufflers for old SL350s are extremely rare and when they finally sell on eBay, I have seen them over $1200. Can't do that.

My K1 can't pass inspection this year cause of a hole. Last year I had a muffler shop weld it. That lasted about long enough for last years inspection.

Any ideas? I can't seem to find any aftermarkets that are black and have the upswept angles. Most are short, loud and chrome.

You could try this guy: http://www.marblesmotors.com/. There are some reproductions, also very expensive. I bought a used set from him for a KO. There is not a lot of options. You could always refinish some chrome aftermarket mufflers in black.

That link says they are no longer selling the repros. When they did, it was $1000 - really out of my league for a daily rider.

I am thinking about some kind of tin can/JB weld patch. What I really want is an inspection sticker.

That may be your best bet. When I still had my SL (sans original mufflers), I searched high and low for options. Decent original mufflers are scarce, and often command high $$$ for what they are.

First time post here :O. Anywho I have my Grandpa's 1973 sl350 and the mufflers were in terrible shape. We kept trying to fiberglass patch them, muffler patch, anything you can think of

.

Anyways I ended up having my cousin braze the small holes, and put pieces of tin over the bigger holes and braze the tin on. I have a few hundred miles on it since then. It is still holding so maybe if you could find a good weld/brazer you could get them fixed.

I had the same trouble as you though...couldn't afford and or find replacement mufflers. So I was running straight headers for a while and cracked the header from the vibration since nothing holds it other than the muffler. Well sorry I couldn't be much more help than that but good luck

I just went out and looked to see if there were any useful markings on my SL 350 K2. Sorry to say that I didn't find anything. A previous owner appears to have taken some short reverse cones and had a piece of tubing bent and welded to the inlets to closely match the original configuration. They are louder than I would prefer but not awful, were originally chromed but painted black. If I was sure they were "keepers" (just found the bike before snow, haven't done anything or even ridden yet), I would probably have them stripped and powder coated.

Bump.

Anyone install a JC Whitney? I am still unable to ride my sl350 due to holes in the left exhaust. At this point I would settle for something chrome and even something louder.

Thanks

Get a couple sportster mufflers at your Harley Shop. There cheap, if not free. Put a bend up pipe in front. Paint black. They will look and sound good.

I looked at some on ePay and it looks like they have no support bracket like my sl does.

Sure, why not,

I'd pay Harley prices for mufflers equivalent to what you can get at a small engine shop.......

.....Not!......

They are dirt cheap on ePay. New ones for $30 + shipping. Some much cheaper than that. Must be that these get tossed EVERY time they sell a new Harley. If that is the case, I will be more than happy to recycle and use the snot outta them.

I've got something similar to these:

on my SL350. They look good and sound good. No chrome flaking after several years of ownership either.

Inspection? What is this 'inspection' thing you speak of? Must be Californy.
