TYPE-R MUFFLER
From This Angle You Can See The Type-R Swaybar Along With The Type-R Muffler.
I have the full Type-R catback exhaust.  For the coupe it is a straight bolt-on affair, as for on the four door like me, I had to weld a 2-3 inch extension.  The muffler itself is a straight bolt-on affair.
The piping of the Type-R muffler is 2.25" mandrel bent stainless steel all the way through.  Has one expansion chamber, one resonator, and the muffler to quiet the exhaust note.  Also the R muffler has a nice welded on tip.  On the dyno I only gained 3hp with the muffler unbolted.
