Brand FuPower 2.5" Test Pipes | VQ35HR/VQ37VHR | 350Z, 370Z, G37, G35 - Stainless Steel Cat Delete Downpipes | High-Flow Exhaust Upgrade | Direct Bolt-On Performance

Unleash the full potential of your VQ35HR or VQ37VHR with Brand FuPower 2.5" Test Pipes engineered for 2007-2008 Nissan 350Z, 2003-2008 Infiniti G35, 2009-2020 Nissan 370Z, and 2008-2013 Infiniti G37 Coupe/Sedan by eliminating the restrictive factory primary catalytic converters and replacing them with free-flowing 2.5" mandrel-bent T304 stainless steel piping that reduces exhaust backpressure, increases velocity, and lets your VQ breathe like it should from the factory, delivering a proven 12-18whp gain with sharper throttle response and stronger mid-range torque while transforming the muted stock exhaust note into an aggressive, raspy, high-RPM VQ howl that screams on cold starts and wide-open pulls, and each FuPower test pipe is built from thick 14-gauge T304 stainless with precision TIG-welded seams, CNC-machined 10mm thick 3-bolt flanges for VQ35HR or 2-bolt flanges for VQ37VHR with exact port matching to prevent leaks and gasket blowout, and a brushed satin finish that resists corrosion, heat discoloration, and cracking for 100k+ mile reliability, and the kit includes high-temp MLS exhaust gaskets, Grade 10.9 zinc-plated hardware, and extended O2 bungs with optional J-style defoulers to help prevent P0420/P0430 CEL codes on most stock ECUs, though a tune is recommended for maximum power and to disable codes on 2009+ models, and they’re available in non-resonated configuration for maximum volume and raw VQ rasp or resonated with internal spiral-flow resonators that cut drone by 70% for daily driving without killing horsepower, and fitment is direct bolt-on using all factory mounting points with no cutting, welding, or modifications needed, clearing OEM heat shields, steering components, and crossmembers on both RWD and AWD models with manual or automatic transmissions, and installation takes 1-2 hours with basic tools since they mate directly to stock exhaust manifolds and y-pipe or any aftermarket cat-back system, and they pair perfectly with FuPower y-pipes, single exit exhausts, and cold air intakes to complete a full bolt-on VQ setup that sounds exotic and pulls hard to 7500 RPM, so if your 350Z, 370Z, G35, or G37 feels choked up and too quiet, Brand FuPower 2.5" Test Pipes are the most cost-effective performance mod for unlocking real horsepower, aggressive sound, and that iconic VQ exhaust character that defines the platform, and every set is pressure-tested, surface-inspected, and fixture-checked for flange flatness and alignment so you get perfect fitment and zero leaks straight out of the box without the warped flanges and poor welds you get from eBay brands.
