ISR Performance high flow cats are custom made utilizing 300 cell spun Metallic substrate to be less restrictive than stock, Letting you gain power while still converting harmful exhaust gasses, ISR HFC are Fully TIG welded with true mandrel bends throughout. ISR Performance HFC bolt up to factory or aftermarket exhaust (as long as the aftermarket exhaust is built from OEM specs). ISR HFC also retains the factory Oxygen sensor location and also adds a more aggressive Exhaust tone.
What’s in the Box:
These are the best high flow cats out there for the VHR platform, perfect fitment and sound quality is amazing.
Overall, happy with purchase I received very fast. The high flow cats made my car sound beautiful. I combined this with my Tomei exhaust with ISR Y pipe. It sounds amazing.
Good but made the check engine light come on.
Bought them no longer than 3 months ago put them on with brand new sensors and the cats went bad in 3 months later🤦🏻
Product was delivered on time. Appeared to be good quality.
Easy installation sound fantastic
They don’t last that long before they start rattling
One of the best high flow cats
Great fit and easy to install, sounds great, this ISR high flow cat is a quality product.
Installed these on my 2011 370Z. I had some cheap resonated test pipes that I had Maganaflow Universal ceramic cats welded on that were okay, but these ISR pipes look so much better and the cats definitely flow better than the Magmaflow units. You can literally see through these where the others have more cells.The car is a bit louder when accelerating, but it has a nice sound at idle and moderate driving. The hardware was awesome and I was impressed with the gaskets. Most of the time gaskets that come with other stuff is crappy.
