🚀 Peitz Performance C8 ZR1 High-Flow Catted Downpipes
Take your 2025+ C8 ZR1 to the next level with the best-engineered downpipes on the planet. While the factory exhaust restricts those massive twin turbos, our high-flow catted downpipes are designed to let your engine breathe, scream, and perform.
The 3.5" Advantage
We are proud to offer the ONLY downpipes on the market featuring a massive 3.5" inlet to the catalytic converter cores. While competitors utilize smaller diameters that create bottlenecks, our proprietary design ensures maximum exhaust volume and minimal backpressure. This translates to faster turbo spool, lower EGTs, and more power across the entire RPM range.
Advanced Thermal Management
The LT7 engine bay sees extreme temperatures. That’s why all Peitz Performance downpipes come standard with premium ceramic coating. This isn’t an "add-on"—we include it to ensure lower engine bay temperatures, protected surrounding components, and long-term durability for your ZR1.
Proven Performance Gains
Don't just take our word for it—the dyno results speak for themselves. As a standalone bolt-on upgrade, these downpipes deliver:
+50 Horsepower on 93 Octane
+30 Horsepower on MS109 / Race Gas
Massive Sound Improvement: Get that aggressive, exotic exhaust note your ZR1 was meant to have.
