Category: Extractors and headers


The MPI Automotive HOLK128S-178 is a 1-7/8in header set on a dual 2.5in full system with 3.5in tips, listed to fit the Holden Commodore VE-VF V8 Sedan (and Wagon). It's the larger-primary, uncoated sedan option for the LS-era V8.
Headers, or extractors, replace the cast factory exhaust manifolds at the cylinder heads. Each port feeds its own tubular primary pipe that merges into a collector before the system continues rearward. The 1-7/8in primaries here are the larger of the two header sizes in this sedan range. Tubular headers can ease exhaust flow off a V8 head compared with cast manifolds, but they're a deeper job than a tailpipe change — they sit tight in the engine bay and need careful clearance and gasket work.
This is a dual 2.5in system — two 2.5in pipes running the length of the car — finished with 3.5in tips at the rear. The 2.5in figure is the working pipe diameter; the 3.5in tip is the visible finisher at the back. The supplier hasn't published a material grade or sound rating for this listing, so we won't state one. What separates this part from the coated sets is the bare 1-7/8in primaries, and from the S3 sets is the 2.5in bore rather than 3in.
It's listed to fit the Holden Commodore VE-VF V8 in Sedan form, with the Wagon covered by the same listing. The model years aren't published in our record, and V8 Commodore builds vary across that run, so confirm your exact variant and driveline with the workshop before ordering.
