I purchased the stainless steel Ocelot exhaust from the Fiero Store to replace my deteriorating stock exhaust. The description on their website reads:
The Ocelot exhaust allows your Fiero to breathe better by reducing back pressure. You will notice a deeper, richer tone as well as improved fuel economy. The system is made from 2" T-409 stainless steel pipe leading into a custom built, free flow stainless muffler. Each system includes dual twin polished stainless tips. These tips are the same that GM uses on the Bonneville GXP's. Stainless clamps included with each system.
Needless to say I was excited to get this new setup!
