        Overall nice exhaust, fit could be better

        The sound is great at idle and under heavy throttle. I think the price is very good for how the exhaust looks. However, the fit was disappointing. I originally installed this myself but had few issues with the fit on the driver's side. No matter how I adjusted it the muffler wasn't straight, was lower than the passenger side and most annoying was the pipe over the axle would hit the underside of the car on sharp bumps. I sent pictures to MBRP and they sent me a new muffler believing it was due to a hanger issue on the muffler. Unfortunately that didn't make any difference. I ended up taking it to a muffler shop and they had to cut the pipe and the weld it for proper fit.

        Went to a muffler shop for install and they said they had to customize fit due to fit requirements. Also the clamps failed to tighten as required and welding was required for proper seal of joints. Now on the vehicle and sounds great.

        Great exhaust system, but ...

        Fit and finish is perfect. Sounds great. I own a high-performance shop, and just recently ordered two exhaust systems back to back. Both had come in the box damaged. One exhaust tip was bent, the other the pipe ends were bent and had to be shaped to fit. Completely due to packaging. The outside of the box was not damaged by shipping, if the MBRP can get it together and pack their product properly, this is a flawless exhaust system

        MBRP cat-back with BBK Lt headers o/r x pipe

        I had Roush axles back originally installed and they sounded fantastic, but once I installed my BBK Lt headers and o/r x pipe it was way to loud for a daily driver. After trying to add resonators to the Roush I found that I didn't like the he tone it had afterwards. In come the MBRP cat-back I now have them installed and the exhaust is as close to stock tone and loudness, not a bad sound but way too tame for my taste.

        Very surprised!

        I did a lot of searching to find the right exhaust for me. I wanted it to be a little louder than stock but still get some extra power and sound. These were the ticket! I installed them over the weekend at my parents place and then took a 2 hour drive home. I was still able to have a conversation via SYNC and no one even really heard the car. There is practically no drone in the cabin and it really only get loud when you jump on it. I would definitely recommend these to anyone looking for a nice change but not something to be loud and obnoxious!

        This is a great product! I couldn't be happier with the new sound. Not too loud (not much louder than stock, really) but still a much better tone. "Mellow" is a good word to describe it; it was just what I was looking for. This is the one for you if you don't want that loud, raspy, nasty v6 sound you get from the smaller mufflers, or for the daily-driven Mustang. The parts weren't perfect from the factory, however, as I had to finesse the hangers a little to get the setting right, and there was a small dent in the muffler outlet that made putting on the tip awkward, but nothing too serious. Aside from that, well constructed, and a breeze to install. Me and a friend had the stock system out and this one on in just over 2 hours. This is an exceptional value, couldn't be happier with how it turned out!

      I have a stock V6 2014 Mustang. Do I need any other parts besides what comes in the MBRP cat back exhaust system to hook up to my Mustang? Thanks, Bob

      • This cat back exhaust system will be a direct bolt on installation and will work directly with the stock location of the mid-pipe with no modifications needed.

      I have a '11 V6 with just an AIRAID intake Tube and SR Throttle Body Spacer (don't judge.) Can I run this without requiring a tune?

      • Yes, you can run the Stainless Steel MBRP Cat-Back Exhaust without needing a tune.
