Robert,I have the Precision Proformance 180's.
My engine is a 408 Windsor. 9.5 deck height,AFR 185 heads,stock port location.
Both Hall Pantera and Precision Proformance have 180 headers for Yates heads,but Halls exit in the corners so you can leave the air conditioning condenser in place.I do not like the Hall corner exit as it sounds like a truck versus the the two exhaust pipes exiting together in the center sounds like a wild V12.

Attached are a few pics to show roughly how they fit in the engine bay.Ignore the dusty engine bay,i have not cleaned it since Laguna Seca.
Everything i have seen that Ron Mcall does has been great,so if he is offering 180's that fit your heads, get his if you are able.

Hi Richard,
could you please let me know
what 180 exhaust did you install?
What
engine (deck height) and heads combination do you have?
A photo would be great!
If I find a 180 system that bolts straight to
my 9.2 deck with Yates C3
heads I might
consider going that route.
Thanks, Robert

"Rich Boschert had
ANSA-sized Flowmaster mufflers, but they were brutally
loud--they almost seemed like amplifiers rather
than mufflers! And they
looked
terrible too."
Hey,i
do not think they were ugly ,(attached a pic if it goes
thru),but yes
they were LOUD : )
The Ansa mufflers and tips are
by far the best looking muffler,but have
horrible flow.
I had Cherry Bomb Extreme mufflers with non
baffled tips.Essentially the are
a hollow
can with one angled metal plate .They flowed well,and had a
deep
exhaust note.Less drone at low rpm than
the stock Ansa's as well.The problem
with the stock Pantera muffler location is you
have to use a short length
muffler,which
makes it difficult to have decent exhaust flow and sound
canceling ability.Also a more powerful engine
will be louder than a stock
engine with the
same mufflers.

>>>What you get
is style and a different sound. You'll
never notice a
performance difference, and
you will pick up weight plus enormous complexity
and hamper maintenance access."
On my car, i just installed
180's with 4 inch Magnaflow mufflers,and it made
a significant increase in power over my already
decent flowing loud
exhaust.In fact the car
revs so quick i am seriously thinking of changing my
final drive gear ratio to 3.73, when i change
the 5th gear in the ZF.
With the 180 exhaust you have a lot more
options on mufflers that can reduce
noise
but still have good flow,because you are no longer as
limited by
muffler body length.You lose your
trunk storage,but is it something you
really
need?If you drop the battery in the front you can gain some
more
storage up front.I started to convert a
trunk that was in really bad shape
to go
around my 180's,but it has been on the back burner since
i have been
able to get by without it so
far.
By the way,the
180's sound GLORIOUS!
