Im about to purchase a Magnaflow catback exhaust and Iv heard videos of the exhaust and Iv heard all around good things, but can anyone give me a real pro's/con's of this exhaust because I want some extra info before I drop $1300 on this

Just had this installed in the last couple weeks. If you look up some reviews on here, you'll hear people complain of drone at the infamous 2k RPM mark. I can say that it is indeed true. There is drone in general from 1.5k RPM to 2.5K RPM peaking at 2k. I find myself avoiding that rev range (which it's hard to). It's bearable for now, but time will tell. When you get on the gas at 2.5k RPMs, it sounds very nice! It's kind of like an exotic muscle car sound. It is loud for only a cat-back system though!

If you do some searching, these systems can be had for cheaper.

^^^they did my 2011 STI exhaust and it droned so bad I took it off 2 days later. The main designer guy has this thing with there 14" thin muffler packs. He uses them for almost every system they make now. Which in turn makes them super loud at WOT and very drone like just cruising. The are next door to my work and I talk to them all the time. Nice guys, but they cant seem to understand we dont want super loud with drone.

I got it used for $900. Sounds pretty good, hell of a lot lighter then stock, and they claimed like 16 HP gain (Dont know about that for sure).... For the price it worked out for me. It does drone like kyleb350 said but besides that, Im happy with it....

I have the magnaflow system and it sounds good. A fellow poster went for a ride and he liked it better than his akra cat back.

Was my first exhaust and I didn't like it much. Droned like crazy and wasn't the greatest fitting, took a lot of bonking and finagling to make it fit straight (although it did after some time)

tips look fine. Mufflers hide well enough. I'd definitely go megan racing over this one, though! The megan racing is 1/2 the price, less drone and lighter, as well as easier to install.
