I also have an exhuast with hangars welded in to fit a S14 (not sure if it will fit S13) that i originally had on my car but succumbed to rust and fell off right at the inlet.
The muffler itself is in great shape, nice deep throaty sound for KAs and not loud enough to attract cops - it has a 4" tip and is larger in size. I personally liked the look. $30 takes it!
the sportlines are in great shape, when we installed the megan coilovers, i didnt notice any scratches on the springs after removal. very good seller too.
