    Stainless Steel 3" Cat-Back Exhaust Kit (Loudest Version)

    This is a “Sound on Demand” exhaust system that produces the sound you want. 993183, 993183BK 

    Solo Performance Mustang GT Street Race Cat-Back exhaust kit is a full 3” stainless steel mandrel bent exhaust kit that fits both the convertible and coupe. This Cat-Back kit is our louder version (louder than our cat-back Mach, Mach-Thunder and louder than our Axle-Back kit) and offers a deep, mean, 60’s muscle car sound without the drone usually associated with a full volume Mustang exhaust system. This is a “Sound on Demand” exhaust system that produces the sound you want when accelerating or revving but becomes much quieter at cruise speeds.

    Solo has replaced that annoying cruise speed cabin drone with a comfortable, non-invasive exhaust note through advanced technology and a painstaking R&D process. Solo’s 2015 , 5.0L Mustang GT Street Race exhaust kit comes with a mid X-Pipe and Solo’s rear tunable J-Pipes. These J-pipes are capped off on the end and as the sound waves enter the J-pipe, they bottom out on the end cap and bounce back. Upon the sound wave re-entering the exhaust flow, it collides with the specific Mustang GT drone frequency and cancels it out. The Solo Tailpipe section has been built with ease of installation in mind. The pivotal, telescoping tailpipe assembly gives you an easy way to center the 4.5” tip the first try. Experience all the Roar your Mustang is capable of without being rocked out of the cabin with Solo’s 3” mandrel bent stainless steel Mustang Street Race cat-back exhaust kit…tomorrow’s technology on today’s Mustang GT.

    How-To: J-Pipes Adjustment and Purpose

    This wonderful sound canceling technology is built into every kit and is the final piece of the puzzle to make the Solo exhaust kits “no drone.” We have found that one length J-pipe works wonderfully on one G8 but needs the length to be slightly altered on the next G8. For this reason we have made our J-pipes adjustable on the top. Just loosen the band clamp, slide the pipe, and re-tighten. We will send every kit at the “factory preset” position, but you will have the ability to adjust as necessary. One inch can make a huge difference in exhaust note and ½ inches can further tweak the sound. Just like a trombone, the different lengths can actually tune out different frequencies. In testing, one passenger liked the higher pitched octave and I liked the deeper sound. This adjustability will allow the owner to tweak the frequency to whatever his wife truly likes. LOL. One pleasant surprise when testing the J-pipes was that we felt vibrations at certain settings in the seat. By moving the J-pipe to it’s optimal position, the vibration was “tuned” out. The position and shape of the J-pipe has been researched and tested on multiple cars and wow does it ever work nicely. After a long ride (30 minutes mostly on the highway), the exhaust system is scorching hot. The J-pipes are actually cool at the ends. They have been positioned to allow the exhaust gasses to bypass them but let the sound waves in. This keeps them clean on the inside and workable. As soot builds up on the inside of any exhaust pipe, it “absorbs” sound instead of “reflecting” it. Our J-pipes have very little exhaust gases entering them so they will continue to work for a very long time. We have made our J-pipes removable for two reasons. If a drone develops after years and years of driving, the J-Pipes can be removed with 2 band clamps and cleaned. This will restore them to their original working state. They could also be removed and capped off when you want to go racing and enjoy the full raw sound that the car is capable of producing. Of course this would mean a drone/hum on the highway. You could uncap and re-install the J-pipes as soon as the race was finished, and the drone would be non-existent once again. 

    I hope this is helpful information
