Pumping Air to a Catalyst

[bucket]

Dual exhaust is a waste of time and money if you don't have an engine that requires that much potential. Most people don't. A single 3 inch exhaust is more than enough for 99% of street driven vehicles. A single costs less, is easier to install and sounds just as good depending on muffler choice. You can always split it and add dual tailpipes if you have to have the look.

Except there's dual exhaust kits. There's no single 3" kits. It would be either more expensive to have someone fabricate the single exhaust, or much more involved to fabricate your own.

Thanks for the info. That makes a lot of sense.
