I have a vintage, new-in-box, exhaust resonator for 1979 to 1985 BUICK Riviera for sale. This resonator is correct for the exhaust systems of ALL Riviera engines used from '79 to'85 Riviera's, Including the 3.8 V6 Turbo. Also, fits the Riviera convertible conversions. This is a quality, made-in U.S.A part from back in the day. Comes in its original box. One thing I like about having this factory exhaust system resonator in place is that it assures the tailpipe exits at the correct length and angle from under the Riviera's rear bumper. You'll note the tailpipe is an integral part of this resonator I'm selling. The price is $45, plus the shipping. Thanks for looking. John
