i might be going to buy a mac 3" y pipe because i just got a mac catback for cheap. i was wondeering how hard it is to have it match up with my existing headers. im not sure the brand, but is it difficult when using parts from different manufacturers? thanks in advance.

 

basically will it fit without a ton of issues

 

someone chime in?

 

It won't fit unless you have Mac headers too. Unless it's the Mac Y made for stock manifolds and you still have stock manifolds. The Mac Y for their headers won't fit with any other headers..
