I would get a Bassani X pipe because it's the best quality and
performance pipe in your list.I would also think about getting
some Nitto 555 tires as we'll to help your traction alot.I have
the Bassani X pipe with cats and the Flowmaster two chamber
american thunder 40 series catback just like you and it sounds
wonderfull and perfect together.
I would subjest getting your Bassani X pipe with converters though.
The sound is a nice muscle car sound and it is quite loud and
somewhat deep.I have drove past cops in the past and I even idled
in traffic right next to a cop and I never got pulled over for my exhaust
being to loud.Not one cop ever even asked about my exhaust set up
either.I got a great deal on my Bassani X pipe with converters at
www.allmustang.com I think I will pass my savings along to you my
friend.Plus this place has excellent customer service and they are pleasant
on the phone also. Welcome to AFM :thumbsup
