I think DBJ posted some of these. I searched trying to find them but no luck. I wanted to compare these to the pictures he posted of the Stock cat w/3in DP.
Thanks
its a metal matrix cat stock and very hard to see unless you cut the stock DP apart a little. So picture a cermaic 400cell per inch cat and add a sort so swirly pattern to it instead of even rows.
FWIW 400 cells per inch is what the government mandates and does all there testing on, any less and you are risking it not working properly in the future.
