Hello everyone, first time poster here and i have a question about the exhaust system on my truck. I have a 1993 F-150 with a EFI 4.9 straight six. I have recently replaced my muffler with a glass pack, but i want to revamp the whole system. I looked further ahead and found that in front of the first cat instead of having one 2.5 inch pipe, there is two smaller ones coming down from the exhaust manifold. I was expecting to just be able to cut off right at the front of the first cat and run a straight pipe back to the glass pack. But how can i go about this with there being a set up like this? Also any pictures of completed systems on similar truck would be great for a visual reference.

Thanks in advanced, Stick 40

 

get a 2 to 1 cat and run a custom exhaust after it

 

The idea of mine is no cats at all, i dont want to spend to much money. What im plaing on doing is running a straight pipe from the manifold back to the glasspack, but i need to figure out how to do this with there being two smaller pipes going in to the front of the cat. Any help is appreciated!

 

you can buy collector pipes then normally its 4 into one but im sure there is 2 to one
