i had a flowmaster 40 series 1 in 2 out put on today. how much louder would it be if i added new long tube headers and high flow cats

Quite a bit, your basically taking all the restriction away from the exhaust, so your truck should not only be louder, but also gain a couple of ponies while in the process

Thanks I'm thinking about taking the cats out completely

Take them out fully. At first you will throw an engine code. Pm me and I'll tell you what to do about it
