The N1 Dual is a hybrid variation of the N1 exhaust. This system incorporates a twin pipe, twin canister design for improved mid-range torque without sacrificing top end power. The twin piping is Full SUS304 piping construction mated to SUS 304 polished stainless steel canisters. Each canister features a polished 90mm (3.54 inch) tip. Robotic TIG welds compliment the hand crafted MIG welds to create on of the most innovative and dynamic exhaust systems on the market.

The N1 Evolution combines all the racing heritage and proven performance of the original N1 muffler but raises the ante by adding light weight, fully polished stainless steel piping. This is the ultimate N1 exhaust system. Mandrel bent, full stainless steel construction provides maximum power gains and resistance to rust or other damage caused by weathering. Like the original N1, the N1 Evolution uses the minimum amount of pipe bends to allow for greater exhaust flow. The N1 Evolution was created for those who are looking for something one step further than the classic N1 design. Available only for a select amount of vehicles, the N1 Evolution stands as a brilliant testament to exhaust system fabrication.
Please note that due to the tapered tip of the N1 Evolution exhaust system the ATS Silencer WILL NOT fit properly. This is only true for the N1 EVOLUTION mufflers, all other exhaust systems will fit without problems.

70mm GT Downpipe For the 87-91 Turbo II RX-7. The A'PEXi Down Pipe is the pipe on turbo vehicles that connects the turbine exhaust housing to the catalytic converter. Although short in length, the A'PEXi downpipes provide incredible amounts of power because the piping diameter is enlarged so early on the exhaust system. This enlargement in diameter results in a dramatic increase in exhaust flow capacity as well as a significant reduction of back pressure. The GT spec Down Pipes are constructed of fully polished SUS 304 stainless steel.
