Great Staff/Great Products

First thing is to give staff at MAP five stars. I ordered my MBRP exhaust on a Tuesday and received it on Thursday. Did I mention there was a hurricane on Wednesday? So two day shipping to Florida around a hurricane, that's service. Now to the exhaust. It was packaged well, no sign of damage. All parts were there with instructions for install and warranty paperwork as well. Workmanship was top notch, clean bends and fit. Install took about an hour total. Started my ST and the sound was perfect, just the exhaust note I wanted. I bought the exhaust because it bothered me that the Abarth sounded so much better than my Fiesta ST but I also got a nice bump in high end torque from the installation. Worth the investment.

Jon Tavares
MBRP Fiesta ST Exhaust

Really enjoy the exhaust. The quality is good, install was easy, and the deep throaty sound. I have this coupled with the high-flow Mishimoto downpipe and my it sounds nasty. Ain't like driving past a group of hot girl, cracking the throttle wide open, and seeing them quiver.

... exhaust is legit!
