I would go with the regular Magnaflow catback exhaust.
It has a nice deep tone at idle and is somewhat quiet
until you go WOT then it will scream.Overall the regular
Magnaflow catback sounds like it is ideal for you.The
stainless steel construction is really good quality and
will last a long time.The nice tips that come with the
Magnaflow catbacks really compliment the exhaust system.
The SLP catbacks make nothing but loud noise and are
quite annoying.Kind of sound like a tactor to me with no
real sound to them and sound like arse I think.
I can't belive folks in the mustang community would actually
put a GM part on their mustang (SLP).
