Just from looking around for the past couple of months I've found:

Advance auto parts carries hooker cat-back systems for about $255 (lt1 w/ dual dual tips)

They also sell the universal magnaflow 3"in/out cats for $70

Also some 1le suspension stuff for CHEAP
here. (near the bottom)

Just thought I'd let some follow owners in on some good deals out there.

Also, I am in no way shape or form affiliated or getting support from these people.

If you guys have found some other good deals post 'em.

 

good finds man
especially on the 1le stuff (although 1le was first offered in 88 iirc, not 92 as they say)
this is a good idea if you can post whatever sales you find during the week
next time i think i'll post about the oil when it goes on sale, they just had one a month ago or so and i saved a bunch on that
