We have the patterns to fit the '89-93 exhaust manifolds or those for the '94/95 manifolds.   The pattern differs slightly only on the passenger side.  

 

Our 2 1/4" down tubes with catalytic converters go from the factory manifolds to the transmission cross member. They will have a flared end and flange like the factory exhaust to hook up to the stock cast iron manifolds. The stock exhaust can be cut at the appropriate point and these can be mated to it or you can continue with the SCP cat-back exhaust system or some other exhaust.

 

Note that these down tubes do NOT go all the way to the resonator.

 

These 2 1/4" pipes will fit both the 3.8L SC and the '91-93 5.0L Tbird/Cougar engines.   These will fit the aftermarket headers or the stock manifolds for the 5.0L application.
