Looking for a quiet muffler

[arkitek]

Yet again I'm looking for a quiet muffler for my 2.5" J-pipe/midsection.
My stock MSP2003 muffler got a hole in it for a little while now.

The stock muffler is probably the quietest option around.
However, Mazda Canada doesn't have the stock one anymore it seems. They only have the crappy/noisy Mazdaspeed muffler that fits regular Proteges also.

Help me please.
Any input would be greatly appreciated.

Quietest aftermarket?
I thought the greddy sp2 was pretty quiet.

Yeah the SP2 seems my only option right now. I do hear it's a bit louder than stock.
It's a catback system too and I only need the muffler though.

How loud is it compared to stock?
I can't seem to find these in Canada. Probably have to order from US.
Which model fits the MSP as there are a few?
I have 2.5' pipes from stock muffler to turbo.
