hey guys,

just looking at getting some high flow cats and extractors to add to my twin 2.25" redback system on my auto sv6.

ive been looking around at the cats and found a few different ones on eBay, just a few questions..

what CPSI should i be looking at? 100, 200 or something different?

would these be any good?
