Product Details

The Dynomax Super Turbo Universal line focuses on controlled exhaust flow and sound management for performance-oriented street and custom applications. Part Number 17731 uses an oval steel body with an aluminized finish, measuring 18.5 inches overall with a 14-inch body length, 9.75-inch body width, and 4.25-inch body height. The single offset inlet configuration and reversible design make it suitable for custom exhaust routing where packaging and fitment matter. This muffler is a direct fit for Jeep Wrangler models listed in the fitment data and is a strong option when replacing a restrictive or worn muffler on a 1997 Jeep Wrangler, 1998 Jeep Wrangler, 1999 Jeep Wrangler, or 2000 Jeep Wrangler before 01/24/2000.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Uses

• Replacing a damaged or rusted muffler in a custom exhaust system
• Reducing excessive exhaust resonance inside the cabin
• Improving exhaust flow in a 2.25-inch pipe setup
• Restoring a mellow performance exhaust note on Jeep Wrangler builds
• Supporting a universal muffler installation where a reversible layout is needed

Installation Notes

Verify inlet and outlet sizing, offset position, and available exhaust clearance before installation. This muffler uses a pipe connection with a single offset inlet, so exhaust routing should be matched to the vehicle layout and existing tubing. For Jeep Wrangler fitment, confirm the model year and note that 2000 coverage applies only to vehicles built before 01/24/2000. Professional exhaust installation is recommended for proper alignment, sealing, and hanger placement.

Dynomax backs the Super Turbo muffler line with a Limited Lifetime Warranty and a 90-Day Performance & Sound Guarantee. Part Number 17731 is built as a high-performance exhaust muffler for consistent flow control and sound management.
