Z1 full 2.5" diameter polished stainless steel test pipes for your VQ35DE equipped Nissan 350Z or G35.

Each set includes:

  • (1) Set of Z1 VQ35DE Test Pipes
  • (10) Bolts, Nuts amd Washers
  • (2) 2 Bolt Rear Exhaust Gaskets

Z1 recommends reusing the factory 3 Bolt Header Gasket or purchase new HERE.  

Our Test Pipes 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.

*Due to the removal of the catalytic converter, this product is for off road use only. We also offer this product with an integrated high flow catalytic converter that can be found HERE.

This exhaust section resides between the exhaust manifold (header) and cat-back section of the exhaust tract. It eliminates the stock catalytic converters to enhance exhaust gas flow and provide the least possible resistance. This translates into more power realized from not choking the engine's exhaust.

Optional:

One roll of Z1 Heat Wrap can be included at a discount rate using the options below. Z1 Exhaust Wrap is ideal for wrapping test pipes, high flow cats, or any other radiant heat sources under hood or under the car. Includes 4 14'' stainless steel ties.
