2020 Jeep Grand Cherokee


When I first bought the Jeep, I only had intentions of modifying the exhaust considering it was too quiet as a 5.7. But after I installed the new exhaust, I had the itch to build my 5.7 in hopes of having it on par with my 392's I've owned in the past. To satisfy that desire, I started doing some research and came across National Speed in Wilmington, NC and they brought her alive. I've enjoyed her for the last 6 months; however, I've gotten to a new chapter in my life that doesn't necessarily need the Jeep or any performance related vehicle. Other things I value have become more priority (mainly starting a family) and another vehicle would be more feasible.

Other Info

I also installed a Stainless Works exhaust which pairs perfectly with the long tube headers and cam. It gives the car a deep throaty sound which always draws compliments. As of today (26 October 2023), I still owe a little under 40k which would be my asking price if I were to sell it. If anyone would offer me that amount, it's theirs. The modifications I listed above are all the work I've done to the car which was bought at 19k miles (currently has 27k miles).
