200 Cell Catalyst: Featuring a spun metallic honeycomb design to prevent fatigue cracking seen in ceramic units, these cats flow massive amounts compared to the factory design and still do a fine job at meeting emissions standards and avoiding check engine lights. Unlike factory catalysts, these do not use expanded vermiculite packing material that can be blown out by the high exhaust gas temperatures of the Supercharged XKR/XJR engine.
Here's a quote from one of our customers regarding his installation of our catalysts:
"I am replacing the stock catalytic converters with with 200 cell high flow cats from Nameless Performance. Without a doubt the configuaration and design of the stock cats is the most restrictive portion of the exhaust.
Here are photos of the NP cats next to the stock units. You can see how much less restrictive the NP design is. Add the reduced cells/inch count vs. the stock units to also improving the exhaust flow, along the special pricing offered by NP, made this any easy decision as the first performance mod to my car.
The NP units are really well made and fit perfectly in place when I test fit them."
