I recently bought an 04 g35 coupe it had 25k mikes on it. Two months later one of the cats went out, when I bought the car it had a kenetix intake plenum and so far I have had no problems, I purchased the kenetix high flow cats, I wanted to see if anyone knows the quality of their products and wanted to hear other peoples opinon on the cats and other of their products thanks

 

their products or ****.... especially the camber arms and the cat.... i would not waste any more money on those two prodcuts....

if i were to buy a new camber arm, i would go with cusco... and the cat? i would leave it OEM.... no need for a high flow cat unless ur going with forced induction.
