Classic muscle cars have a distinct sound, but some cars need a bit more help getting that perfect boisterous rumble than others. Thankfully, companies like Flo Pro and Lunati exist and help make that classic muscle car sound easily attainable from both ends of your vehicle. Case in point, the ‘67 Camaro RS/SS in this YouTube video. Check out the difference a Lunati camshaft and Flo Pro performance exhaust system upgrades made on the Camaro’s overall audio presence in the before and after video above.

The ‘67 Camaro RS/SS is equipped with a standard 350ci. ZZ4 crate engine from GM Performance with Jet-Hot ceramic coated headers and an aftermarket exhaust system. While the Camaro doesn’t sound bad upon startup, it definitely leaves a lot to be desired as far as acoustics goes. So what do you do? You add a performance camshaft and exhaust for the correct amount of cam lope and throaty sound!

Flo Pro offers numerous exhaust systems and components to give your car the perfect sound. As an added benefit, your car will breath better and may even gain just the right amount of audible performance you were looking for. Just the same, Lunati has a whole line of camshafts dedicated to giving you performance backed by optimal engine tones.

After the Camaro is equipped with a Lunati Voodoo Camshaft and Flo-Pro Mufflers, the car sounds completely different. Even from the rear of the car, you can hear the lope of the custom-ground camshaft echoing perfectly over the exhaust note. Both the new mufflers and Lunati camshaft speak for themselves in this video. So if you’re looking for a reason to upgrade or just enjoy the tone of a proper sounding muscle car like we do, relax and enjoy the video above. And don’t forget to crank those speakers!
