Exhaust Question - 8V

[Scirocco-Al" <scirocco-Al@insight.rr.com (Scirocco-Al)]

If you have an 8 valve then you must change the horrid manfold before you
will see any real increase.  Most sources say you will get between 7 to 10
percent more power from that alone.

The techtonics exhaust is nice, but the muffler is junk.  I bought one and
then replaced the muffler with something better later.  And it is from the
cat back, not including the cat.
