        How does the pro series differ from the xp series aside from material used. There is no sound clip for it yet but this one(pro) shows a scale reaching the red zone.

        • The MBRP Pro Series Cat-Back Exhaust will have more of a deep and mellow tone. The MBRP XP Series Cat-Back Exhaust w/ H-Pipe - Race Version, item # 389208, ( has a very deep aggressive sound. It will definitely be louder compared to the Pro Series.

        Why does one answer from American Muscle say that the MBRP Pro Series Race Version has a more aggressive sound than the XP Race Version and yet another answer states that the XP Race Version has a more agressive sound than the Pro Series Race Version. Which one is the more aggressive sound? Thanks :)

        • We apologize for the confusion on our site. While both exhausts would be a deep aggressive sound this exhaust here would be slightly less aggressive while the XP Race version would be more aggressive tone and a bit louder than this exhaust as well.

            It'a Alright.

            Overall, I gave this cat-back a two star because not only does it drones constantly (and sometimes at an unbearable decibel), but it is also not made to fit. The fitment of the right muffler tip was completely off due to poor weldings on the hanger. As a result, the right muffler tip is always touching the rear bumper. You can typically smell the stench of melted fiberglass and paint about 10-15 minutes in normal driving.

            Speechless .. Amazing Deep Tone..

            I have been searching for that true muscle car deep sound for several weeks , After reading reviews on numerous exhaust. I made my mind up that I was going to get the MBRP Cat-Back Race Black Series. The day I was going to place my order I seen this exhaust and what caught my eye on the MBRP Pro Series was that it is stainless steel and that was the only negative I had with the MBRP Black Series was over time it would rust and I had accepted that. All the reviews on the Black Series had one thing in common, "Loud" and I watched all the YouTube videos and fell in love with it. If you look at the color loudness graph under the Black Series and then look at the color loudness graph under the MBPR Pro it shows to be twice as loud. I bite the bullet and click buy. Within a hour I was wanting to call American Muscle and see if I could change my order from the MBPR Pro to the MBPR Black. Two days later UPS delivered my new exhaust, It took me roughly and hour and half by myself in my drive way using jack stands all the parts were perfect , no issues at all. I hesitated to fire it the first time, looking around thinking my neighbors are about to flip out . I fired it up and OMG it has the most amazing deep throaty sound. when its idling it isn't loud at all just a nice mello deep rumble , Once you hit the gas pedal oh my it comes to life With a deep deep aggressive sound that can be heard coming from a mile away. I take my hat off to MBPR engineers on a perfect exhaust system. My factory exhaust had drone in 6th gear 60 MPH to 70 MPH range that could be annoying at times. I have had this exhaust 3 days now , day two I took a road trip and zero drone , driving down the interstate you can have a conversation with out talking loudly etc. But once you hit the gas pedal this exhaust will blow your mind , I have a 2017 GT Premium with 3.73 gears MBPR Pro Series Cat-Back Race ROCKS!!!
