HSV Monaro (2001-2006) VZ & HSV 5.7L & 6.0L V8 Coupe twin 3in exit L&R DPE Formally Diffilpo by Manta Exhaust

This high quality, Australian made Manta exhaust system for the Monaro replaces the factory exhaust system, including the headers off the engine*.

It gives some good gains, particularly removing the restrictions of the standard system, adding responsiveness down low in the rev range.

The system is available with a large straight-through muffler, which keeps the exhaust noise level close to the factory levels, with no annoying drone inside the cab.
We've also got other options to give you more noise, including hotdog and pipe-only options for a much louder note.

The mandrel bends and straight through mufflers on our Monaro exhaust system ensure the highest possible flow, and along with that comes maximum performance and fuel economy.

Choose from your choice of materials, being aluminized steel, or 409 grade stainless steel.

MPI Automotive Pty Ltd manufacture and distribute MANTA Performance Exhausts – Australia’s largest range of street and 4×4 exhausts, and are a 3rd generation family owned company that was founded in 1974.

In March of 2019, Manta Performance acquired the  DPE product line (Formerly Di Filippo) and production facility in Melton Victoria. 

Made in the same place as before

The next thing you should know is that these exhaust headers and systems are still produced in the same factory in Melton Victoria that DPE operated from. They are made to the same exacting standards by experts who are focused on the highest levels of quality. The single-minded commitment to excellence that DPE had been known for lives on under Manta ownership.

We have made some improvements that you will appreciate

There’s always room for improvement. In that spirit, we have made some useful changes to enhance the already great quality of these former DPE products as we have integrated them into the Manta line.

These products are finished to even higher standards and will fit your vehicle even better than before – they are now covered by Manta’s longstanding 100% fitment guarantee! On top of that, we have increased the former DPE 5-year warranty on all stainless steel headers and systems to a full 10-year warranty, the same as Manta’s stainless steel exhaust components.

It all adds up to a complete line of exhaust system products that you can trust

If you liked the DPE systems, you will love the Manta-made versions! We have taken something that was really good and made it even better. These former DPE products are a great fit with the entire Manta line, underscoring our dedication to providing you with the best-designed, best-manufactured, and best-performing exhaust systems you can buy. Bolt one on and see the difference!
