Hi Paul and all

   We started our Renesis 4 port last week.
   A few bugs to iron out but otherwise all good.
   There has been a lot of talk about exhausts in the last week.
   Here are some photo's of what we finally decided on.

   The original renesis exhaust headers have been cut back maintaining the
   expansion joint in the inner sleave which is about 2" upstream of
   the flange
   which has been tig welded as per the original.
   The rest is 2.5" 064" stainless and slip joint into a "Gonzo" mufler and
   then exiting the cowl at ~ 45 deg through what will be a cowl flap.
   The unit is held in place by the header flange and a stainless clamp and
   braket.

   The Gonzo mufler consists of spiral flutes between the outer wall of the
   mufler and an inner stainless tube of approx 3/4". So looking into
   the end
   of the mufler you can see straight through the inner 3/4" tube while the
   rest of the gasses travel down the spiral before exiting via a tail
   pipe.

   Cheers

   It is probably OK because it is an RX8 engine with 200 F cooler and more
   benign exhaust. You would not get away with it on a 13B however :)

   Interesting motor mount what I can see of it. Can you take
   some pictures of the over all motor mount so we can see how
   you did it?
