Get that Sweet-Thunder sound with our reproduction Chevelle chambered mufflers and tailpipe resonators.

In the original Chevelle chambered mufflers the front inner baffle tube was 2 1/4" in diameter which was expanded up to 2 1/2" to accept the larger 2 1/2" header pipe. The exit tube from this front chambered muffler was 2" in diameter. The resonators were 2" in diameter in and out. We offer these chambered mufflers and resonators as our base package.

For improved exhaust flow, our oversized chambered mufflers and resonators are a better bet with 2 1/4" inner baffle tubing throughout. They allow for a 2 1/2" header pipe and 2 1/4" tubing for the rest of the system.

This is what the exhaust sees on the way in and the reason for our great sound.
