So I bought a header and looking to buy an aftermarket exhaust I don't really like very loud on these cars so what is the quietest catback for these cars?
custom piping with magnaflow cat, very long resonator and dynomax super turbo muffler or cobalt ss muffler(if you plan on going 2.25/2.5") The cobalt ss muffler is said to flow as good as a magnaflow but way less noise.

This, the best thing with this option is you can go with straight through and glasspack style offset output mufflers and have a deep mellow tone that is not loud whatsoever.

I like the cobalt muffler on my vert, I also have a 18" glasspack as a resonator. Its quiet, its got a little growl, and it flows really well, just an ugly SOB. Flows well enough that even with stock manifold and cat i am still having an issue with my o2 not getting hot enough. BTW with an eco you wont have that problem because they are electronically heated...which is what i will be switching to very soon.
Cobalt SS muffler all the way...
the LSJ (SS Supercharged) muffler is 2.25 in 2.5 out
the SS Turbocharged muffler is 2.5 in and 2.5 out...
Since you aren't boosted, you won't need more than 2.5"
The ss turbo muffler will drone, or at least thats what the ss eco guys that have tried it say. I would not get a magna flow cat there are much cheaper options which work just as well if not better.

i don't throw a code either...
then again... when my PCM took a dump and resulting melting of the internals of the cat occurred, i gutted the cat... still no code
i'll replace the cat after this spring rebuild
