    Would like to make a mention to SOUL Performance for the amazing quality and excellent customer service. This Pennsylvania based company recently opened a brand new state of the art facility in Willow Grove. From the point I showed up til the time I was ready to come pick the car up, they gave me step by step updates on everything they were doing with the car. The quality of the exhaust is second to none and the sound couldn’t be better. The car received the cat-less competition headers along with the back section with a upgraded muffler to reduce the drone. The tone is absolutely amazing, and the drive ability of this exhaust is amazing. I would recommend them to anyone.

    I installed the Soul Performance Cat back system almost a month ago. As reported by a number of people already, I was happy to confirm the built quality, efficient design plus service and support I received from Soul Performance, especially John @ SoulPP

    As the cat back system broke in over 12-15 heat cycles, some of the initial sound resonation issues I had went away but I was still getting what some may describe as slight drone under extreme loads (flooring gas at 2000-2300 rpm in 3rd , 4th gear). I reached out to a few people and I was told to replace the 152,000 mile old Stock Headers. The Cats in my headers have been shot for a long time and I needed to get new headers anyways.

    Happy to report that adding the headers to the cat back absolutely fixed any / all resonation issues I was having.. and let’s remember, I have a 152,000 mile otherwise stock car with tired and old stock suspension , trunks seals etc so in my opinion that says a lot about how well designed this product really is.

    I share this with great humility, but I have been “modding” and tuning Cars and Sport bikes for close to 30 years, and I can say this with absolute confidence that Soup Performance Full Exhaust system is hands down the Best system I have ever added to any of my vehicles. To reiterate, there is no “….given the price” or “…for the money” at the end of that statement. It is the best I personally have tried…. period.

    Sound: I was extremely skeptical of the videos on youtube as sound can be manipulated, most microphones don’t ever pick up accurate real world exhaust sound. I also heard one of the users on youtube use a phrase ( Ferrari like Wail ) that sounded like a lot of exaggeration..
    Well, happy to report that I was wrong! I really have no other ways to describe the WOT sound you get after 4000-ish RPM.. Ferrari F430 like wail..
    I don’t know how its possible to get that kind of exotic sound from a flat 6.. but the folks at Soul have found a way.
