Product Details

The Dynomax Ultra Flo Welded Single System 19399 is built around a straight-through muffler that reduces restriction compared with a conventional chambered design. The muffler uses continuous roving fiberglass technology to help control interior resonance while preserving a deeper exhaust note. With stainless steel muffler construction and steel piping, this system is aimed at long-term service in a performance exhaust application.

This exhaust kit is a direct-fit cat-back setup for the Chevrolet S10 and GMC Sonoma Wide Stance Package applications listed above.

Common Reasons to Replace the Exhaust

• Restore a damaged or rusted cat-back exhaust section
• Replace a restrictive factory exhaust with a freer-flowing system
• Address exhaust noise from a worn muffler or pipe section
• Correct fitment issues on a modified or aging Chevrolet S10 or GMC Sonoma exhaust
• Upgrade to a stainless steel muffler assembly for improved durability

Installation Notes

This system is designed as a bolt-on exhaust kit for the listed applications. Verify Wide Stance Package fitment before ordering, and confirm pipe routing, hanger locations, and outlet clearance against the vehicle before final installation. The kit contents listed by the manufacturer include the required pipes, muffler, clamps, and gasket components for the application.

For best results, inspect existing exhaust flanges, hangers, and mounting points before installation. A proper test fit helps ensure the tail pipe, angle exit, and round tip alignment match the vehicle body and rear suspension clearance.
