Hey Matt
Single chamber Flowmaster mufflers are really only for race cars that run where mufflers are required for noise control. I would use them on a strip only car, or a show car that you drag race too. They are not for the street. The noise level would get annoying after a while, and I like a rumbly exhaust note. I would recommend two chamber if you are going to run cats and three chamber if you don't run cats. Just run a larger diameter exhaust tube size, if you are worried about restriction. I currently run a full 3" single exhaust system on my '93 3.3 liter Dodge Caravan. It has a Products for Power 3" in/out cat and a three chamber Flowmaster 40 series center in/out. The pipe exits in front of the passenger side rear tire. I really like the Walker Dynomax muffler sound too.
