I've seen a few clogged or very leaky factory mufflers. I'm pretty sure leaky can actually be worse for MPG in some situations (and definitely your health). I'm a fan of straight through design, the simple is engine doesn't usually have to push as hard to exhaust. |

When he brought his car to my shop he showed me the muffler. It was totally plugged. |

The tailpipe rust off my son's 97 Swift, and the cheapest route was replacing the whole system at the local muffler shop. Tossed the cat and factory muffler, bought a cheap glasspack and ran 1.75" pipe to the muffler, 2" pipe to the rear. Power increased slightly, MPGs took a dive. |
