resonator size

**OsideKid** · 07-07-2012

I have a 2003 SE 3.1 L, and i want to replace the resonator with a glasspack and also want to get a new muffler.....anyone know the size for the both of them?

2.25" in and out if your still stock

the res is 2 1/4 the muffler pipe size is 1 7/8th, but if you are having them welded up, they can do anything.

You may want to just go with just doing mufflers at first. Some GP's with the resonators removed have an annoying drone to them when your driving. It all depends on exactally what you go with i suppose and as long as you like how it sounds go for it.

I thought it sounded nice on my Impala for the first few months. But since I don't drive it as much as my GP, I haven't put a resonator back on it. When it gets demoted to my daily driver, it will have a resonator installed.
