Y pipe replacement
Alright, so I either need to weld my y pipe or get a new one. I found one on Summit ( http://m.summitracing.com/parts/wlk-40279), but not sure if it would work. My truck has the "California emissions" bullshit with two extra cats, but they're not needed for me in PA. Can I get a y pipe without the cats? Or do I absolutely need one with cats for my engine to function properly...?

Hello again.
One cat will give you enough back pressure, along with the stock exhaust. if you go high flow on the exhaust, you MIGHT have trouble with back pressure, but the biggest effect will be loss of torque at a lower RPM. as long as your sure the part fits and the single cat is enough to pass you on a E-test, you should be OK.

Hey redneck, noticed the part you posted is for a 5.0, 5.8 and 4.2. be sure what you order will fit.

I was just looking at this y pipe after following your link. The application chart shows it fits the early 80's models of the bronco and ranger with a V8. Are you sure this will work on your '01 Ranger? I am looking for exactly the same thing for my '06 4.0L Ranger. However I would prefer a 2.5 inch. I'm also wondering is this Walker y-pipe mendrel bent? If I only install one cat on each side, will sticking to 2.25 inch y-pipe instead of 2.5 inch help keep my back pressure as it should be if I am running high flow cats and a flowmaster muffler? And if I stick to a 2.25 inch y-pipe, should I run a 2.25 inch muffler? I was planning on running a single 2.5 inch flowmaster. Keep us posted, I'm curious what you find out. Here's a link to the thread about my y-pipe project.
