1.5" to 2" pipe to the cats then some Borla mufflers. Looking at about
$1200 or so for the dual cats/pipe/mufflers/labor/parts. Plus your ECM will
probably freak out due to the increased flow so you will need to program the
computer for the new flow. Probably can be done for $500 if you can find
someone that is able to flash the Taurus ECM.
You will probably gain some low-end performance, but high end will fall flat
quickly. Your fuel mileage will drop drastically due to the new flow
Just get a SHO and be done with it.
There is nothing wrong with the Taurus. My Vulcan has enough power to
blow away a Honda last week up a hill. It was a young kid at a stop
light and it had them coffee can exhaust on it. He was revving up beside
me making all kinds of racket and when the light turned green he got to
see t his old man's tailights. Join the Taurus Club mentioned in the
last post. Lots of info there. I'm a member myself and also
Bill, I have a 89 SHO and I put on the Borla stainless setup when it
was available. (I dont think it is anymore) It consisted of the larger
center pipe from the flex coupling back and 2 mufflers. I also changed
the Y pipe with one from the SHO SHOP. The Y pipe has mandrel bends and
hi flow cats. The Y pipe was the big bottleneck in the system. The sound
from this system is fairly quiet. You can hear a slight growl about 2k
rpm. Probably quieter than what you are looking for. It did increase
low end torque a bit. I also went to a 73mm mass air meter. Getting the
exhaust out wont do much if you cant get the air in. For me this
combination is just fine.
If your Y pipe is restrictive, you might want to look into that also.
