Borla ATAK or MBRP?
 

I have the MBRP, came with the car, but I'm wondering if there's any advantage to switching to the ATAK? Thanks!

You're not going to change anything besides exhaust tone and volume by switching to a different axle-back system. You do have the option of keeping NPP with the ATAK. It appears your MBRP is not NPP compatible, but that may or may not make a difference to you.

Unless you're dissatisfied with the tone/volume of the MBRP or want NPP (assuming your car had NPP to begin with), then save your money.

^ He's right.

The Borla would probably sound better than the MBRP though.

I've got NPP. Just wondering if I'd squeeze more HP and get a better sound with borla.

Horsepower, if any, will be marginal. If you're looking to change the tone/volume, go for it. If you're looking for power, look elsewhere. Start with changing the X-pipe, headers after that if you still want more (though you'll need a tune with headers).
