Personally I prefer stainless for exhaust. Your best bet is to go with the zzp 3", Zzperformance.com . They will have the good cat and flex already on it. But these cars computers can be finicky when it comes to aftermarket cats so you might need the o2 sim or have the code shut off in the PCM. Wbodystore.com's isn't bad either.
But you should just save your money and get a 3800 motor. The 3100 is crap.

Don't make another thread, 3100 guy.
You already got one going.
