I need to get a high flow cat for my car Its a 95 z28 with MAC headers and Y pipe. The cheaper the better because Im selling the car in the spring. The dynomax looks good but I am not sure of the part # tbyrne and thunderracing only have the random technology which is like $250.00

 

Summit has a Catco brand for cheap. Not the top of the line converter, but it's a free flow style cat. Flows at 450 cells p.s.i. $60.00 for a 3". Which I'm running on the TA.

yea randon tech aint cheap

 

$100-$150 is what you should pay, and the $150 is only if the flanges are already welded on. check paid advertisers first
