Got kinda tired of a fairly loud exhaust. I had a perfect condition muffler from a 95 z28 camaro in my attic for 10 years that I dug out and installed in the Fiero. I had to cut out the bottom 3-4 inches of the trunk to make it fit but it sounds super quiet - perfect for a 40something year old like me. I may have to change the name of my fiero from Dimemachine to Ghost. I think it will be more fun than ever sneaking up on ans spanking mustangs with only the whine of the SC making sweet noise... Did some backpressure testing as well and I have 6psi of pressure at 6000 rpms - not too bad for how quiet it is.
