The Pinnacle of Australian Exhaust Engineering
Di Filippo Exhaust (DPE) systems are more than just parts; they are performance-tuned instruments. Crafted from the highest grade 304 stainless steel, every DPE header and cat-back system is designed to maximize scavenging and flow for high-performance engines, specifically the GM LS-series V8s found in late-model Holdens and HSVs.

Why DPE Leads the High-Performance Market
Maximum Scavenging: DPE headers (available in popular 1 7/8" and 1 3/4" sizes) are engineered to pull exhaust gases out of the cylinder head more effectively, resulting in massive power gains.

Drone-Free Performance: Meticulous internal muffler design ensures an aggressive exterior sound without the annoying cabin drone often found in lesser systems.

Investment Quality: DPE systems hold their value and are built to last the lifetime of the vehicle, even in high-horsepower forced-induction applications.
