So, I've been re-thinking my set-up and researching.
What do you think?

Header: Same as above, maintec 4-2-1

Cat: OBD-2, CARB legal High Flow Cat (Magnaflow)

Piping: 2.25"

Resonator: Not Sure (Should I put one on?, I've been told they help keep out a lot of those hight pitch sounds).

Muffler: Also Not Sure. What muffler's are you guys running? I've used Magnaflow before, any other brands I should look at?

 

Magnaflow is good. ANd I would throw a resonater in to. That should have a real good sound with the Maintecs. You have intake and bbtb at all?

Not yet, but intake is on the list.
I'm thinking AEM Cold Air

 

go with the new exhaust redz has you will love it...if you dont...

mine setup is obx headers, carsound cat, summit racing glasspack, and ebay n1 knockoff muffler

and i love the sound of it...

make sure you get it under axle less bends more free flowing

 

N/A standard here is any where from 65mm~68mm anyting bigger you will kill the backpressure and tibby need some unless you have the BOOST.. and that is the standard 76mm for 350hp anything above that 100mm from downpipe back..

 

Finally Figured out.

Header: Maintec 4-2-1

Cat: Magnaflow High-flow Cali legal cat

Muffler: 6" Round body Street series Muffler

Piping: 2.25" prob just steel.

Still iffy if I want a resonator or not.

 

A resonator/glasspack can't hurt. I would get a glasspack, it's pretty cheap (you can get a Thrush from summitracing).

 

Definitely get a glasspack! If you want the deep sound, that's where it comes from. Go for the longest you can. RedZ just fit a 36 inch one, so you should do pretty close to that. Don't go below 28" if you're able. And yes ^^ they are really cheap, so you have no excuse since you have the maintechs... Also, I'd recommend a different muffler, rather than that straight through one. A baffled one will give you much better sound than the straight through that you have. (Have you read the link that RedZ provided??)
