Product Details

Dynomax Super Turbo Universal Part Number 17749 is engineered for drivers who want a performance muffler that balances flow and sound control.

This makes it a strong option for a Chevrolet C1500 exhaust muffler replacement, GMC C1500 exhaust upgrade, or other 1988-1993 Chevrolet and GMC truck applications listed in the fitment data.
