Exhaust resonator

[fwdmaster]

I'm in the market for a 3" resonator and wanted to know whats a good resonator to get and what size length I should get.

Vibrant resonators are good. I own the ultra quiet on a full 3 inch turbo back.

There are two main types of resonators. Perforated core and louvered core. Perforated cores do not affect exhaust flow at all while louvered core resonators will flow about 5% less but are also quieter. Your choice should depend on your sound goals. You can also get them in varying lengths, obviously the longer they are the quieter they will be able to make your exhaust. RRE has a good selection in lengths from 12" - 24" and 2.5" - 3" diameters in both designs.

Here is a comparison picture from their site. A perforated core is on the left and louvered core is on the right.
