Re: Feedback on taking off cat..

Well for one if you are in Ca you can't legally take the cat off especially on a vehicle that has to be smogged in Cali most pre smog vehicles didn't have them there are a few exceptions like my 76 never had them from the factory and it is atleast twice as loud as my Blazer but it also has dual exhaust but almost every Chevy/GMC truck after 76 had them. my opinion would be to get a CARB approved high flow cat
