Description
We take Flowmaster's best 40 Series Delta Flow Muffler and custom modify it to fit your Fiero.
Replace your original muffler while preserving a stock appearance and factory fit. It works well with your existing catalytic converter. You many also add a free flowing cat for even larger power gains. The Flowmaster muffler has 2-1/2" in and two 2" out Ports.
The "Super-Flo" Muffler is louder than stock, but has a nice mellow, aggressive tone.
