Default Anyone heard of these small 3" cats?

They are on ebay made from T-409 Stainless Steel. Its a spun desgin so its really small 4" across by 11" long. The lenght could be shortend some too. They are just as small as those new magnaflows or the dynatechs. They might not flow as good though, but for less than $50...i'm game.

A couple different sellers, but its the same cat. Model # 410300 Their is also a 425300, which has an O2 bung on it.

had the exact same ones but the lower cell density ones.... there is two different types on their ebay website

took them off my synergy custom true duals because i wanted LOUD

i've heard there's only about 1~3rwhp difference with them

blows any other high flowing cats out of the water $$$ wise

Still can't find em'. You had those with the XS headers right? Were they right off the collector or where? I couldn't fit a cat off the driver side because it tucks so high!

here's a few pics with them when they were installed on the car with custom true duals (and yes those are the XS Stainless LT's):
