1989 Jeep YJ Repair Question
1989 Jeep YJ 6 cyl Four Wheel Drive Manual
I have a 1989 Jeep Wrangler Sahara w/ the 4.2 inline V6. I want to buy Pacesetter headers, a Magnaflow high-flow cat, and a 4Wheel Drive cat back exhaust system. I want to bolt it all on myself and I'm concerned they won't be compatible. The collection tube diamter on the header is 2 inches, the cat inflow diameter is 2 1/2 inches and the ouflow 2 inches, and the cat back system in 2 1/2 inch diameter. Will these all go together?
for the exhaust i would imagine the headers do not come with the downpipe so it will go headers stock downpipe cat and the rest off the exhaust...but i dont know the sizes off the 4.2 off the top of my head but if the sizes are close enough you can get couplings from any auto parts store just make sure you know the id(inside diameter) and od(outside diameter)
