Z1 full 2.5" diameter polished stainless steel 300ZX Twin Turbo Testpipes complete with gaskets and hardware.
This exhaust section resides between the downpipe 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 better spool up of the turbos, and more power realized from not choking the engine's exhaust stroke. We typically see increases in power of ~20RWHP on stock cars and as much as 50RWHP on heavily modded cars.
These aren't the smaller diameter cheaper testpipes you might have seen on eBay. 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.
Will fit all North American Z32 TT models with 5 speed and automatic transmissions. 1996 models require an aftermarket performance cat-back exhaust.
*Due to the removal of the catalytic converter, this product is for offroad use only.
