70-71 Pontiac GTO 2.5in Exhaust Splitters Pair

The 70-71 Pontiac GTO 2.5in Exhaust Splitters Pair from PYPES Performance Exhaust delivers the classic musclecar aesthetic while improving exhaust flow dynamics on first-generation Judge-era performance platforms. These slip-on exhaust tips are engineered for Pontiac enthusiasts and restoration specialists who demand both authentic appearance and measurable gains in scavenging efficiency. Built for the serious builder, this pair replaces factory restrictive outlets with performance-oriented dual exits that complement high-flow headers and mid-range engine modifications.

Each splitter features a 2.5-inch inlet that mates with standard collector diameters, transitioning to dual 2.25-inch round outlets for optimized exhaust velocity and reduced backpressure across the RPM band. Constructed from polished stainless steel with single-wall construction and a cut-edge angled finish, these 10.75-inch-long tips resist corrosion while maintaining the authentic split-exit look synonymous with 1970-71 GTO performance variants. The angled cut design directs exhaust gases away from the vehicle body and rear quarter panels, reducing heat soak and contributing to cooler underbody temperatures during sustained driving or competition use.

Installation is straightforward for mechanics familiar with exhaust systems—the slip-on design eliminates welding and permanent modifications, allowing fitment over existing collector pipes or as part of a complete exhaust system overhaul. Weighing just 4.73 pounds for the pair, these splitters are ideal for stock restorations, restomod builds, or period-correct GTO authenticity projects seeking both visual impact and functional breathing improvements. Compatibility extends to any 70-71 Pontiac GTO platform equipped with dual-outlet collector systems, making them a bolt-on upgrade for LS conversions and traditional small-block or big-block combinations alike.
