Chevrolet Silverado 1500 ZR2 6.2L V8 Cat Back Exhaust System with Centre & Rear Muffler.
Category: Mufflers and resonators


The MPI Automotive SSMKCH0014 is a cat-back exhaust built for the ZR2 version of the Chevrolet Silverado 1500 6.2L V8, running a centre muffler and a rear muffler. The ZR2-specific fitment is the key here — the off-road-focused ZR2 sits and routes differently to a standard Silverado, so this system is shaped for that truck.
The Silverado 1500 ZR2 is the lifted, off-road trim, and its underbody packaging and clearance differ from a regular 1500. This cat-back is listed for the ZR2 so the run clears that truck's setup. A cat-back replaces everything from the catalytic converter rearward, leaving the emissions hardware ahead of it in place and reworking the silencing and tailpipe section behind the cat.
Two mufflers — one centre, one rear — split the silencing across the system, which suits a big 6.2L V8 by controlling the note in two stages for a settled result rather than one loud rear box. It's the comfort-conscious way to free up a full-size V8 truck. MPI Automotive hasn't published the bore or material, so confirm those with the workshop if they matter to your build.
It's listed to fit the Chevrolet Silverado 1500 ZR2 with the 6.2L V8. Because this is trim-specific, confirming your truck is the ZR2 — not a standard 1500 — matters before ordering. The workshop can verify your exact build.
