I can sell you my Ohlins if you wish. They're a good street set.
I also have another pair, standard rear and Koni front dampers with Eibach springs, street-spec.
I've never cut one up, but apparently the JASMA exhausts have reduced piping in the mufflers or something? Either way, I'd concentrate on other areas of the car, unless you really want a louder exhaust.
You don't know what you want?
Your budget is $600. You want an aftermarket/bigger exhaust. What are you trying to figure out?
You want a titanium turbo back or something?
Go down to your exhaust shop, tell them you want a 3" cat back with two mufflers.

If you actually read the replies in the other threads you created, your best bet would be a second hand cat back, or getting one made up at an exhaust shop in mild steel.
Yep I'd agree, but my Kraken Pro headset (got it on sale of course) has been good so far. That's the only Razer I have. Looks like lots of issues with their hardware, priced way too high.
Heard the mice are good apparently.
I'm almost always touching the case when handing PC insides. A habit I developed a while back .
Try running a GTX 760 ITX version, only one fan and condensed PCB/small heatsink. My card hits 80°C and throttles (even at fans running full blast).
Anything below $400 won't have a decent camera, unless you get a repaired/2nd hand phone (I bought a Xperia Z2 for ~$400 off here last year).
Grab another iPhone? 4S? Since you're already in the Apple ecosystem.
