90 Cat Converters - ZR-1 Net Registry Forums

Any input on cats on the 90 as to new and improved, removal or gutting?
My 90 just started a loud rattle from either the cats or shielding.

Any thoughts or headers out there?

have you given thoughts to putting headers on the car. then you could get some good aftermarket cats that would rob less hp and be easier to replace should the need arise. you also could see if you could find someone that would let you put the car up on a rack ( one that holds the car by the frame) start it up and listen for the sound under the car. hope this helps
