Sportmax Design Cat Fooler

Hi guys,

Fitted a set of Sportmax design cat coolers to my N54 downpipe yesterday as I was getting error codes. Car pulling smoother??Have any of you guys had experience with these foolers previously and success?
Well priced at R150 each. Understand that MHD software can sort but pricy. Thoughts please

Im confused, are these Cat Foolers or Cat Coolers, or none of the above? A fooler that tricks your downpipe into thinking theres a Cat attached?
