Detailed Product Description

Built for direct replacement service, AP Exhaust 700109 features a 4.06 in. body height, 10.5 in. body width, and 20 in. body length in an oval aluminized steel shell. The muffler uses a single center inlet and a single right-center outlet, both with 2.5 in. inside diameter pipe connections. Its baffled internal design and OE-comparable sound level make it a practical choice for restoring exhaust function on a Chevrolet Blazer, GMC Jimmy, or the listed Chevrolet and GMC truck and Suburban applications. AP Exhaust 700109 is part of the MSL series and is not tunable.

Common Problems This Muffler Can Address

• Rust-through or corrosion in the original muffler body
• Exhaust leaks caused by a damaged muffler shell or internal failure
• Excessive exhaust noise from a worn factory muffler
• Poor exhaust routing match when replacing a direct-fit MSL/Maximum Muffler
• Need for a replacement muffler with OE-style sound characteristics

Installation Notes and Tips

Confirm inlet and outlet orientation before installation: this muffler uses a center inlet and right-center outlet with 2.5 in. pipe connections. Verify vehicle-specific fitment for your Chevrolet Blazer, GMC Jimmy, or listed 1987-1988 Suburban and 1987 truck application, including notes for dual exhaust and GVW-specific coverage where shown. Because the body is aluminized steel and no heat shield is attached, inspect surrounding exhaust components and hangers during replacement.

Quality Assurance

AP Exhaust 700109 is a regular-grade exhaust muffler from AP Exhaust’s MSL series, built with aluminized steel construction for service replacement use. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
