[s-cars] louder exhaust

[Robert Pastore]

Setting aside the cats (which are an obvious restriction in any system), the
worst part of the stock system is the cast iron section of the downpipe that
bolts to the turbo.   You cannot see the extent of the obstruction until you
remove the pipe, but there is a huge restrictiom.  Maybe 15 or 20% of the
area at the top of pipe is blocked by a "dimple" which exists in order to
provide wrench clearance for the bottom inner turbo to downpipe bolt.

  I've had a great experience with Stomung and their system.  I'm running
the
Stomung downpipe and center section(no cats) into the stock resonator and
muffler.  I fabricated a connector from 3" to 2 stock pipes going into the
resonator.  Barely louder than stock sound, no drone, better flow--maybe.
My
guess is the major restriction on the stock system is the downpipe and cats
so I bet I freed up a few hp.  Lost a significant amount of weight.  It
works
great for my RS2 setup.  Definitely seems to spool up faster.
