k75 aftermarket pipe on ebay
« on: February 04, 2018, 01:42:07 PM »
stumbled across this, great price, not sure brand, may be a MAC.  These things are scarce and the seller does not know what he has!  If nobody grabs it I may buy it and resell it for $200!

I was offered a Staintune a few weeks ago while looking at a stock muffler. I had visions of modifying the stock one, fortunately common sense kicked in. However from what I have been able to find out over the years is there is no performance advantage to be gained. Only noise. :dunno2:

Absolutely true.  But I love the looks and sound of the MAC I scored back in 2012.  And it's held up very well.  The stock muffler's whine annoyed the hell out of me and the MAC has a nice tone that almost disappears at highway speeds.  I also have the airbox delete K&N cone filter that also adds nothing to the bike's performance but looks cool.  Actually, freeing up that space under the tank may make it run cooler.

The whine in mine disappeared after I stopped carrying a pillion. :hehehe

I have a Staintune muffler that needs a new finish, looks burned-up like the MAC on this post. The plating looks like brushed stainless over steel.   Has anyone had success in re-plating these? 

Has anyone noticed lower fuel economy with aftermarket (through) pipes?

I had to look-up "pillion", now I'm the one laughing.

You can try cleaning with very fine wet and dry and follow up with stainless polish and stainless cleaner to maintain. A bit labour intensive, but you will have the satisfaction of a job well done. :clap: I cheated on my OEM muffler and used 6" buffing wheels on my bench grinder, for the hard to get places I used a air grinder with cotton mop attachments. You have to be careful with some aftermarket mufflers they are not built as substantial as OEM in wall thickness, and can ding easily. I do seem to remember somewhere BMW recommending OEM mufflers be cleaned with French chalk only.
