Milltek H-pipe valved cat-back system for the Chevrolet Camaro Gen 6 6.2L V8, LT1 and LT4. Direct factory fitment on OEM hangers and mounting points, no cutting or modification. T304L stainless throughout with hand-finished quad GT-115 4.5 inch polished tips.
Fitment: 2016 to 2024 Chevrolet Camaro Gen 6 with the 6.2L V8 and the factory dual-mode valved quad-tip exhaust (NPP). Covers SS and RS optioned with the naturally aspirated 6.2L LT1 (SS 2016 on, RS 2017 on), and ZL1 with the supercharged 6.2L LT4 (2017 on).
NPP was standard on the 1LE and ZL1 and optional on the SS and RS, so check the car rather than the badge. The 1LE and RS were also offered with the V6 and the 2.0L turbo, which this system does not fit.
Does not fit: cars built with the non-valved single-outlet exhaust, the 2.0L turbo four, or the 3.6L V6.
The H-pipe configuration balances the two banks and cancels cross-cylinder resonance, giving a deeper and more settled note than the straight-center layout. Mandrel-bent piping keeps the bore constant through every corner so scavenging is not choked at the bends. Acoustic tuning is decibel-tested to build with throttle rather than boom at cruising RPM.
- T304L stainless steel, mandrel bent throughout
- Quad GT-115 4.5 inch polished tips, hand finished
- H-pipe layout for a balanced, deeper tone
- Requires the factory NPP valved quad-tip exhaust, reuses the OE valve actuators
- Direct factory fitment on existing OEM mounting points
- Dyno-proven gains on the 6.2L LT1 platform
Check this before you order: this system replaces the factory valved quad-tip exhaust and reuses the OE valve actuators. It will not fit a car built with the non-valved single-outlet exhaust. Look under the rear valance: four tips and a valve motor on each muffler means you are good.
Engineered and built by Milltek, backed by 40+ years of performance exhaust heritage. Tested on the Tail of the Dragon.
