Glasspack on a 258??? Y/N

Don't know the physics but it's completely true on my old truck. I think an in line engine just doesn't have that issue as a general rule.

I ran a glass pack and a flowmaster 44 series on my 258. The Flowmaster had a deeper sound nice rumble. The glass pack was ok but sounded raspy at times. Go with a 40 or 44 series flowmaster.

2 adaptors from 2.25 to your size pipe and call it done.

I've got that running back from the Clifford through a y-pipe into a single in/out Flowmaster.  If I remember correctly, they did a 2.5 inch tailpipe to make it an awesome resonator. angled toward the ground at the back.  Might be 2.25 all the way, can't recall right now.  Love the sound, but I don't spend a lot of time listening to radio anyway.
