that glasspack sound

[69hugger]

I've heard some of those trucks, and thought they must be running straight pipes. Gawd, that must get old after awhile.

Magnaflows & Borla's seem to be the "in" brands these days.
My Flowmasters, which were the big thing, say 15-20 years ago, seem to be yesterdays news. They sound good to me, but what do I know... I'm an old fart.
Hell, I started with Cherry Bomb's & Thrush's. And let's not forget "Purple Hornies"!

The Porter website has some sound clips, if that helps you.

But a lot of it comes down to the cam timing & compression.

Best,

Bill
