I have been asked by several people to describe my 2 into 1 Termi
pipe polishing experience. I will do so on this site so all who are
interested can read it.

This was my first polishing experience and the Termi is really
expensive (~$1800 USD)so I was reluctant, but the factory finish
is so poor that I decided I could do no worse. So,I attacked the
job. I made several errors(I polished,then ground the welds!) which
really ate time and resulted in
less perfection than I wanted so I will describe how I should have
done it-not how I did it.

Tools required are a bench grinder (~$65 US at Home Depot)with a
smoothe grinding rock,220 grit (or smoother) Emery cloth,cloth
polishing wheel and white rouge ( Sears). I used a 6" grinder
because that's what I had-I think an 8" would be better.

First,grind the weld(s) as flush and smoothe as practicable with as
smoothe a rock as you can find for your bench grinder. I ground the
large weld
on the muffler, the smaller one close to the "Y" connector and the
ones that show on the "Y".Be careful to grind only the weld and not
the stainless steel around it--you can smoothe it up but it will
take a lot of time and effort. Also,I concentrated on the part of
the welds which will show when mounted-not to ignore the backside
but not to spend too much time.

After grinding the welds to flush with the surface,I sanded the area
with 220 grip emery cloth. Be careful not to over do this but you
want to make the area as uniform as you can.

Next,put a polishing wheel on your grinder. I bought mine at Sears.
I used the white polishing rouge,also from Sears (Home Depot,Lowe's
and most good hardware stores will have it,too.). Then,go to work. I
found that using frequent rouge applications and light pressure
worked best. All it takes is time and patience.

Once the weld areas were polished to my satisfaction,I moved on to
the pipes and other areas of the muffler and "Y" connector. How long
this takes depends on you.I wanted mine to match the mirror finish
of the Staintunes on my Yamaha FJR1300-I got pretty close.

I live in the South (Alabama)of the US so I can ride all year. You
Yankees,Cannuks and Euro types will have all winter to do this work.
I'll bet you can do it well!

Do not hesitate to ask questions.
