im looking at the pacesetter lts and see there are two different parts numbers- one for 93-95 and a different one for 96-97. what is the difference?

 

cat converter location

 

im not going to be using cats so will they work on my car? im getting them used is why i ask

 

The Pacesetter long tubes come in different versions because of the minor differences in the AIR connections. The 93 has different AIR locations so they don't make a specific emissions set for them. 94/95 have same AIR locations as the 96/97, but use a larger diameter thread for the connection, 96/97 uses a smaller diameter thread for the AIR connection.... hence, two different part numbers for the "emissions" headers.

If you don't plan to run AIR and EGR, you can buy the 93-97 non-emissions model.

Since they are "long tubes", the locations of the cat(s) are irrelevant, since the LT's do not attach to the stock cat(s) in any case.

From the Pacesetter website:
