Show original supplier description
The Boosted 6 Autowerks B6A VR30DDTT Non-Resonated Lower Downpipes are engineered for enhanced performance on the Q50, Q60, and 2023 Nissan Z models equipped with the VR30 Twin Turbo engine. Constructed from durable 304 stainless steel, these downpipes utilize mandrel-bent piping to ensure optimal exhaust flow with minimal turbulence. The 3" tapered piping design aids in efficient gas evacuation, and 2.5" reducers are included to facilitate integration. The construction features TIG welding for strength and longevity, with OEM fitment to the upper downpipes utilizing lip and crush gaskets to prevent leaks. Installation includes all necessary gaskets and hardware. These downpipes are intended for off-road/competition use only and are not street legal due to their un-catted design. Buyers must acknowledge and sign a race car waiver, as the product is sold exclusively for race use and compliance with all local, state, and federal laws is the responsibility of the buyer. Fitment is confirmed for 2017+ Infiniti Q60 VR30 Twin Turbo, 2016+ Infiniti Q50 VR30 Twin Turbo, and 2023+ Nissan Z (including all submodels).
