[DeTomaso] Ansa Baffles

[Jim Wallace]

Tom,

I have a set of GT5-S mufflers.  The pipe leading to
the muffler is good size about 2.25 inch, the problem
is that it neck's down when it hits the muffler.  When
you open your up I think you will find this.  The pipe
is welded onto the outside of the muffler shell bit
the internals are the same siz as my stock muffler
1.625 inches.

Good luck.

Jim
