hey guys i know this question has probably been asked hundreds of times but im new to this truck scene ive always owned mustangs before this so dont kill me.

anyway ive got a 04 silverado 5.3 and i have a flowmaster catback, on my truck but i want louder. i was thinking of gutting my cats but how hard is it to do on these trucks? can i do it myself and if so whats the best way? what do u guys recommend?

also ive seen a few posts about the dynomax bullets if i ditched my flowmaster for 2 of these would that make it alot louder than it is now to save the hassle of gutting the cats?

any help is appreciated and thanks in advance

i cut mine off and gutted them then welded them back up and i have stock exhaust 3'' with a magnaflow out the stock location and it sounds awesome.

Just unbolt the y-pipe. There are 3 bolts at each collector and 2 bolts where the 2pipes merge into one. Use a hammer and long screw driver or pipe and gut the cats. Then bolt the y-pipe into place. Should take about 2-3 hours.
