Take advantage of freeing up your exhaust while not picking up the "Rasp" commonly associated with test pipes when used on the "HR" and "VHR" engine platforms.
Each order includes: on pair of High flow cats, one pair of 2.5 inch Multilayer Metal 3 bolt gaskets, and one pair of 2.5 inch 2 bolt gaskets, and all necessary hardware.
Often the RTV sealing method or composite gasket for the 3 bolt flange from the manifold to the test pipe doesn't hold up over time due to extreme exhaust temperatures and can fail leading to irritating exhaust leaks and potential Check Engine Lights. To solve this potential problem Z1 has designed and produced our very own multilayer metal exhaust gasket for this application. This gasket is similar in construction to the manifold to turbo gaskets we have used for years on turbo applications. It has proven to be one of the strongest and most robust parts on any car we have used them on; these gaskets can be removed and reinstalled countless times without any problems. Now we include them in our kits, and make them available separately here.
Z1 full 2.5" diameter polished stainless steel 2003-06 350Z / G35 testpipes complete with gaskets and hardware.
Our testpipes are built to fit properly as well as welded on both sides of the flanges and ground smooth on the insides for great fitment, strength, and flow.
Z1 350Z HR SS Test Pipes $269.00
Z1 Motorsports 350Z HR SS Test Pipes for all '07+ 350Z HR (VQ35HR Equipped models ONLY!)
Residing between the headers and the mid-pipe section (Y-pipe), the Z1 Motorsports SS Test Pipes replace the existing, factory Catalytic Converters. By removing the Catalytic Converter, a major restriction in the exhaust system is eliminated allowing for increased flow. Test Pipes are a great addition to any vehicle looking to extract that extra bit of power, whether it is stock or modified.
The test pipes include the following components:
Z1 Motorsports 350Z HR Stainless Steel 2.5" Test Pipes
Grade 8.8 Zinc Coated Hardware (x8)
Composite Exhaust Gaskets (x2)
Mulitlayer Metal Manifold to test Pipe 3-bolt Gaskets (2)
Additional benefits include:
Reduction in exhaust gas temperatures
Inclusion of a secondary Oxygen Sensor Bung - allowing for either a Exhaust Temp Gauge or Wide Band Air-Fuel Sensor
Unique exhaust note - a direct result of freeing up the exhaust
Light weight - A 43% weight reduction as opposed to OEM Catalytic Converters
Full Stainless Steel Polished Piping and Flanges
OEM fitment - No additional labor or fabrication is necessary for installation
~ 10 - 15 RWHP Increase!
Please note
Like many aftermarket parts, these test pipes are intended for off-road use only. Please check with local laws when installing aftermarket parts!
Z1 Motorsports cannot guarantee that any of the different brands of high flow catalytic converters we sell, including our own, will not cause a CEL (check engine light). From our experience it is not a problem on 90% of cars. However if your car does throw a CEL, we can provide you a Uprev ECU reflash to eliminate it at a great price.
