I have your setup, but use a Cherry Bomb glass pack as the center muffler This is a red cylindrical muffler with no welds. It performs well and sounds good! This muffler is normally used on domestic (US) performance custom cars.
Just for grinns I checked on a pipe for my Spider. The price was lower with out putting in "ebayrocks". Before buying I would suggest getting a price both ways.I bought mine from performancepeddler.com if you enter a coupon code of EBAYROCKS you can save another 15% or so....
