Gudday,

I'm in the process of customising my LS650 - which means changing the exhaust, among other things. Two problems seem to arise though;

1. 2" pipes are BIG, not many of the mufflers I like/want come in the right size.

and

2. In NZ you have to keep exhaust noise down to 100dB or lower.

I was at one point thinking of just taking the muffler off and putting a baffle in the pipe but I don't know whether that'll pass inspection noise-wise. Anyone got any experience with changing their exhaust under similar restrictions?

The Ryca guys also sell a reverse cone muffler made by Emgo for their kits. It's $60 us. from them, but you can find the same mufflers elsewhere as well. Might be a local supply there in NZ?

Theirs connects with an adapter that they sell for $45, but you could probably have something made up for much less at a local muffler shop.

Even still, for both parts, it's $105 us. brand new, and that's not bad.

These are a bit louder than the Dyna; you'd have to ask them about the exact noise levels, but as you can see, they can be disassembled and fresh packing added to reduce the noise. I'm sure they would pass with added packing... Something that's also easily found at any auto shop.

Remember; the Savage muffler is much larger outside than it is inside. It's 2" outside, but only about 1&1/4" inside. Pull off your stock muffler and measure the exact size of the inner diameter, and then do your shopping based on that...

It's about like this here...    HEY JOG, I'M YELLING RIGHT NOW!    

Seriously, it's about like a jackhammer in a construction zone with you standing perhaps 50 feet away.

Then a Supertrapp w/ 14 disks would pass the 100 db test? IDK,, I can Make it be loud as heck,, by rackin it off,, or, I can ride past a Hospital & not worry Im disturbing the patients, How the wrist is used makes a big difference in how noisy the thing is, & whether or not the engine is used for braking,,

Theres a pipe in a pipe. I cut the center pipe out, & had the header welded back together, Been that way for years, its holding up fine,

If I had it all to do over, Id go to a muffler shop & have a piece of exhaust bent to match the header & have a Reverse Cone welded in at the head end,
Once the pipe rusted a bit, Id wipe it with Ospho. I think it would look good.
