how much the hi flow cats run? i dont have inspections or laws here so would i get more power from new cat or replacing it with pipe?

 

avoid the troubles of being found not running a cat.. it's a federal law.. I've 'heard' tales, though I don't know if they would validate or not, of folks running w/o cats and being involved in significant accidents where a responding police officer noticed the vehicle w/o cats, and the insurance refused payment because the driver was operating a "non street legal vehicle"... dang.. I think that was the longest grammatically correct sentence I've ever written..

A high flow cat (universal) will cost you about $60... A 'direct fit' under a benji.. There isn't that much to be gained by running straight pipes..

just my .02
