After running my 2006 Chrysler 300C at London Dragway in Kentucky, I drove away both very impressed and wanting more. The big barge had turned better times than I was expecting; honestly, instead of the 14.8 that the car did run, I was expecting a mid-15 second time. The 300 has plenty of potential, but being a Chrysler, and not a Charger or Challenger, Chrysler saddled it with options that were targeting the geriatric crowd: a suspension setting that is pretty much marshmallow, gearing that is meant for cruising at the lowest possible RPM ever, and an exhaust note that isn’t going to scare a field mouse. Here’s a tip: if the word “HEMI” is going to be emblazoned across the vast expanses of this car, the loudest noise that it makes should not be coming from the cooling fan or the key-in chime.
I’ve blamed my love of Mopars on the influences of my grandfather, Ken. Ken was a lifelong Mopar buyer for decades, usually driving Chryslers. His pattern was very typical: Nice dark color, the highest-level interior, the most powerful motor, and the quietest exhaust note possible. His cars are a laundry-list of this pattern: 1977 Town and Country, 1984 E-Class, 1989 New Yorker, 1993 New Yorker Fifth Avenue, 1998 Intrepid. Ken liked his cars quiet, unassuming and pimped out. His grandson, on the other hand, couldn’t be a further polar opposite. When I moved in with him at the age of 16, I bought a loud-by-obnoxious Monte Carlo SS that had only the basest of luxuries (stereo and t-tops), faded paint, and loud pipes. I loved the car. He hated it so much that one night, when he was in the middle of Heart Attack #6, he actively insisted that we take his car instead of mine to the emergency room (even though by that point I knew my car was seriously faster.)
Therefore, with that backstory in mind, meet BangShift’s newest project car, Project Angry Grandpa. Why that name? Easy: Stock, Grandpa Ken would love this car. But with what I’m gonna do to it, he would be reaching for his blood pressure meds while screaming at me, blue in the face. Some minor touches have been done, like tinted windows, but overall, this thing is as stock as it gets. I found it in the used section of a Ford lot in Prescott, Arizona and got it for $13K…after a ton of issues with the dealership. It was a low-mileage car that had been owned by snowbirds. Even now, at eight years old, the car only has about 84,000 miles on the clock.
The first thing that was necessary for the 300 was to actually sound like it meant business. In stock form, the 5.7-equipped Chrysler whispered wherever it went with an exhaust note that sounded more Camry than Hemi. Magnaflow stepped up and solved our problem with their cat-back system for 5.7-equipped Mopar LX cars (300/Charger/Magnum, p/n 15629). This is a bolt-in stainless steel replacement system that deletes the freaking huge “suitcase” muffler and equally huge end mufflers for two reasonably sized mufflers and a resonator. All of the stock hangar locations are used and the system comes complete, ready to go. Anyone who can spin a wrench can put this together easily. If I can do it under an oak tree in the grass, you can do it in your driveway. Trust me. Check out the photos below and see what it took to get Angry Grandpa’s yelling up to the right volume. The video is at the bottom of the page and the sound is great! We love it!

UPDATE: The rattling noise returned. Ronnie at Modern Automotive in Bowling Green, KY threw the 300 up on a lift, where we found that the pipes were contacting the crossmember. Pipes were re-adjusted, and the crossmember was shimmed for additional clearance. Problem solved. Just because it’s well-done doesn’t mean that you might not find a small thing like this with a kit.
