I have pacesetter lt's and this is a pacesetter y-pipe that I
fabricated... (second time welding)
i used 2 magnaflow high flow tc's and you can see where it feeds into my 4" mufflex exhaust system...

I have one question for the experts...
will my lines be ok?
FYI: The lines are no closer than 1/2" from the cats...
And the cats do have a built in heat shield...

I put this here because this section is viewed more and this is LT1 specific...

 

nice. nodnarb481 on here has that setup but with mini cats. fits good

 

I don't think anyone has said you can't. I had one fabbed 6 years ago. My concern is it looks like the drivers side is uncomfortably close to the fuel lines. Good work nonetheless.

 

nice

 

Nice work. Its not an easy thing to do, but definitely possible. I had a pair of mini-cats welded into my Pacesetter ORY pipe.

 

Nice job, weld's look good.

 

it is very uncomfortably close.. unlesssss you move them like i did. Ill try to find some pics of mine

 

I would move your lines.. its not hard but it is very tedius work (dont mind the spelling or the fact that I probably used that word wrong) I did it by hand but you can buy pipe benders (much better idea) Its a simple solution to what could become a huge problem

 

Would I want a 600+° cat that near my fuel lines?

 

good point ^^^

 

what about the brake line? will it vapor lock?
