My 89 GT has both tail pipes stress break at
the apex of the hump over the axle. Both at
the same time???
They have been used for 2 sets of mufflers
and were probably way past their life
expectency. Mufflers are semi dented/rusted
from NEPA roads.
Mufflers from NAPA $46 each (18244), and Pipes at
$30 each (45991).
Any better deals on this or other system?

 

A Napa cat back for your stang will be nothing more than a cheaper version of the stock system. Spend a little more and get a little more.
