I have a 1984 K5 Blazer with a silverado package and i have to say the best exhausts for a K5 would have to be glass packs i had a 305 in it and it sounded like a beast now were putin a 350 in it so its might be louder [sm=icon_rock.gif]

 

I love the sound of set of 40 series Flowmasters in the morning!

 

thats what i got on mine, well only one. i was thinking of throwing on my gibson muffler thats on my s10 now (im putting a magnaflow tuner style muffler coming out the roll pan on that) for a change of tone. might sound kinda nice.
