My friend just got glasspacks and no cats on his 1990 chevy 1500 305 and i was wondering if this sort of set up would sound alright on my 1999 4.2

 

if you want a deep rumble, glasspacks on a 6 cylinder probley wouldnt be the way to go. Rather, Id look at a performance muffler. I love glasspacks on V-8's, but think 6cyl's sound good with them, too much 6 cylinder crackle.

 

There are much better sounds available on a 6. Search over in the "V-6" area; many have responded to similar questions.
