[DeTomaso] NEED SOURCE FOR 180 DEGREE HEADERS FABRICATION

Tue Oct 23 23:32:52 EDT 2007

I have the aforementioned 3" pipes on my car. (no crossover pipe)

The headers are custom for A3/C302B heads and 3" collectors.

The pipes snake through the A-Arms.  There is a small dent from the 1" sway bar - mounted in the normal orientation.  If it is mounted below the a-arms, it wouldn't dent at all.  Keep in mind, the dent is very small.

The mufflers are Borla XR-1 race mufflers, powdercoated black with chrome tips.

I like 'em.
