VY VZ V8 HSV Sedan 3in Dual With 1 7/8 in Extractors Hotdog/Muffler.
Category: Extractors and headers


The MPI Automotive SSMKHN0136 is a 3in dual extractor-and-exhaust package listed to fit the VY-VZ V8 HSV Sedan. It runs 1-7/8in primary extractors into a twin 3in system with a hotdog-and-muffler rear layout.
This is a full engine-back build for the VY-VZ HSV Sedan V8. It begins with 1-7/8in primary extractors at the heads, then splits into a twin 3in run that passes through a hotdog resonator into a rear muffler. The 3in dual sizing is the larger-bore option for these cars, matched to the extractors at the front.
Extractors replace the cast exhaust manifolds with separate tubes that merge downstream, and the 1-7/8in figure describes the primary tube diameter at the heads. The aim is to reduce back-pressure and pulse interference where the gas first leaves the engine. Behind them, a dual 3in run keeps both banks of the V8 flowing rearward, with the hotdog smoothing particular tones ahead of the muffler. The honest trade-off is that header-led work is a heavier fitting job than a bolt-on rear section, so the system is supplied complete to keep the sizing consistent from the 1-7/8in primaries through the 3in pipework.
It is listed to fit the VY-VZ V8 HSV Sedan. The 3in dual run with a hotdog and muffler is the larger-bore choice in this family. HSV builds and options vary across the VY and VZ range, so confirm your exact model and specification with the workshop before ordering.
