I have a 96 GL-Sport with a 2.0 liter an 5-speed. The rear muffler is 13 inches long, found a similarly sized turbo muffler in the JCWhit catalog. Since the car has a 1 7/8inch exhaust, would I order a 2.0 inch muffler (so that it fits over the stock pipes)? Where can I get decent work (AT A FAIR PRICE) done in the NoVa area?
