I tried to buy one as he does them from 99p in auctions at times , when he started bidding me up I stopped bidding and he then second offered me and I declined
They are made by direnza , look at their website for better pics , welds don't look to good and the inside of the cooler casting looks rough which won't
help flow ,
But it's your decision , I also don't think them pipes are the right shape to fit properly ,
I'm selling my kit soon , it's good for 225bhp before the cooler maxes out and gets hot as core is small to fit behind bumper open to offers but want £100 all hard pipes included and pancake pipe which is widened and welded to cooler hard pipe
