Resonator on turbo exhaust?

[BlazedGlory]

First of all, the desired exhaust size for a turbo engine is about 3", correct? Second, would it be ok to put a resonator (probably about 20"-24") on the cat-back, or would that cause too much backpressure?

Thanks in advance...

Idealy, one wouldn't want any restrictions except for the cat...I think the best setup is a high flow turbo outlet, and cat...3" downpipe and a 3" exhaust with a high flow muffler at the end of it.

well, I kind of want it fairly quiet... Audible, but quiet...and deep...

my apexi gt spec came with a resonator in it so they cant make that much difference

A turbo is a very, very good sound deadener. My apexi n1 duals sound very quiet on my KA-T, well.. for being so large they're quiet. I have no cat, but plan to replace my dummy cat (s14) with a hi-flow cat, and expect the noise level to drop even more.
I say wait until you get a turbo and the exhaust, and if it's too loud, then plan on how to fix it. Chances are, it won't be that bad. Especially since you don't live in Cali.

agreed with Jeff. my N1 duals were starting to get annoying a loud as they were on the stock KA. put the sr in and it was tons quieter. turbo the bish first then see how you like it. still to loud THEN fixt it
