ISR Performance High Flow Cat Pipes Nissan 370z Z34 2009-2017 / Infiniti G37 2008-2013

Fitment Info: These high - flow cat pipes are a great fit for 2007 - 2008 Nissan 350z with VQ35HR, 2009 - 2020 Nissan 370Z, and 2008 - 2013 Infiniti G37. Note that they're compatible only with vehicles having OEM HR/VHR headers, not DE - style shorty header swaps, and won't fit convertibles. ISR Performance high - flow cats are custom - made using a 300 - cell spun metallic substrate. They're less restrictive than stock, helping you gain power while converting harmful exhaust gases. They're fully TIG - welded with true mandrel bends throughout. These HFCs can be bolted to factory or aftermarket exhausts (as long as the aftermarket exhaust follows OEM specs). They keep the factory oxygen sensor location and give your exhaust a more aggressive tone. What's in the box: 2 stainless - steel high - flow cats, 2 two - bolt exhaust gaskets, 2 three - bolt exhaust gaskets, 2 O2 extension pipes, and 10 pieces of hardware (bolts and nuts).

Using these ISR Performance high - flow cat pipes is straightforward. First, make sure your vehicle is one of the compatible models as mentioned (like 2009 - 2020 Nissan 370Z or 2008 - 2013 Infiniti G37). Check that your vehicle has OEM HR/VHR headers because it won't work with DE - style shorty header swaps or convertibles. When installing, use the provided hardware like bolts, nuts, and gaskets. You can attach these pipes to either the factory exhaust or an aftermarket exhaust that's built to OEM specs. Keep in mind that the oxygen sensor location is the same as the factory setting. For maintenance, regularly inspect the pipes for any signs of damage, like cracks or loose connections. If you notice any issues, get them fixed right away. With proper use and maintenance, these high - flow cat pipes will keep your vehicle running smoothly and give you that extra power boost.
