The Chevelle is one of Chevrolet’s most powerful (up to 450 horsepower) and successful mid-sized muscle cars. Not only did the Chevelle boast a sleek body style but it also came with a high-performance engine. Nowadays the classic Chevelle has become one of the most sought-after muscle car restoration projects. Starting from the inside out, most Chevelle restoration projects begin with the installation of automotive sound deadening to dampen the noise of the Chevelle. B-Quiet.com sells a range of automotive sound deadening products that can be used to quiet your Chevrolet Chevelle.
Why Chevelles Are Noisy
Muscle cars like the Chevelle were engineered for performance first. That leaves plenty of room for noise to enter the cabin:
-
Thin floor pans transfer road and tire vibration.
-
Large metal panels in the doors and roof resonate like a drum.
-
Exhaust drone fills the trunk and rear cabin.
-
Engine and headers produce heat and noise through the firewall.
-
Old seals around doors and windows let wind intrusion in.
Restorers love the raw sound of a big-block V8, but without sound deadening the ride can feel more like a track car than a cruiser.
B-Quiet Ultimate Automotive Sound Deadening
The engine of the Chevelle is powerful and loud, that is why the team at B-Quiet.com recommends applying Ultimate Automotive Sound Deadener. While restoring the inside of your Chevelle, you can apply Ultimate in a few key places to reduce engine, exhaust, wind, road, and tire noise.
Where to Apply B-Quiet Ultimate Sound Deadener in your Chevelle
For maximum automotive noise control and insulation, the B-Quiet team recommends applying Ultimate on the floor, firewall, doors, in the trunk, roof and tunnel.
To apply Ultimate to the floor, firewall, roof, and trunk of your Chevelle, you simply remove the carpet, seats, and headliner, and apply the peel and stick sound dampening material directly onto all metal services. The process is simple and will only take a few hours.
Ultimate can also be applied to the doors. To do this, the interior panels must be removed, and Ultimate can be placed on the inside the door skin and then the door.
For additional insulation, you can apply B-Quiet HLiner to the transmission tunnel, and back wall of your Chevelle to reduce vibrations in the engine bay.
How Much Material Do You Need?
A full Chevelle interior typically requires 80-100 sq ft of sound deadening material for complete coverage. Use Ultimate for large panels like the floor and trunk, then add Hliner to the firewall and roof for blocking engine noise and heat.
