[DeTomaso] Headers

Tue Apr 12 15:50:33 EDT 2016

And don't assume that an original style exhaust system will fit either, I recently fitted an original new Ansa system and initially the muffler tips were about 30 degrees off horizontal when viewed from the rear of the car. The only option was to cut off the flange and re-weld on the car to get them right, but it takes courage to cut a brand new exhaust.

Fortunately a set of Borla's I fitted to another car had a slip flange so could be rotated to fit easily.
