I went for MBRP - and would do it again 100%. Super affordable, perfect fitment, sounds fantastic IMO (little drone, but nothing too bad) *I do have a K&N CAI, so that may help with the sound...Only changes I made to it was cut about 1.5 inches of the exit pipe off so the tip sticks up a little higher out of the rear end (to help prevent it from getting smashed - & personal pref.), I also opted to weld on the muffler rather than use band clamps because they have the potential to expand and contract with heat causing the ability to leak condensation & I didn't like that, OH & I gave it a good polish with this stuff:

I have zero complaints after having it 6 months. For $299 not exactly sure why anyone wouldn't go for this system. My system was made in Canada - not exactly sure why people think they come from China, but that's false.
**I also live in Southern California so the weather has not played a role in any rust issues (as of yet)
