    cat or no cat?

    Having the fiero V6 engine with the f355 exhaust will I get a better sound with or with out the cat converter. Or is this one of those that I am the first to try it?

    Just a side note: Removing the cat for track use will let you install larger Camero injectors to gain a horsepower advantage. If you simply remover the cat in addition to reducing the back pressure with a 355 muffler or a Fiero muffler for that matter, you will cause the engine to run lean and over time, melt away the pistons. If your going to drive it on the street with a basically stock engine, keep the cat.

    If you're not confused, you're not paying attention.
