I've been working with an exhaust shop to build a cat back exhaust for my 2002 4Runner using a Magnaflow muffler. I'd prefer it to be a bolt on exhaust system, so that I can remove it down the road if necessary to replace it with stock. The exhaust shop said that was no problem, but they can't locate a flange to match the one on the stock system. Anyone know where to fin done? I've looked on Google without much luck. LC Engineering seemed to have some but only for the 3VZ.

I'd think a 3/8" or 1/2" flange 2-bolt design is what is needed to connect this custom cat back to the flange after the 2nd cat?

 

If your having trouble getting a flange you can always have a machine shop with a waterjet cut one out of plate stock for you. Then just have the muffler shop weld the flange to the pipe and you're done. The waterjet is pretty easy to use and cheap to run, but prices will vary depending on where you live (I would think Nashville would have a few shops that could handle that kind of work).

 

Have you tried going to a junk yard and just cutting one off there?

 

just cut off the flanges off another tacoma,4runner exhuast

I had thought about cutting one off another 4Runner or Tacoma, but wasn't sure if Tacoma flanges were identical to 4Runner. I assume they are?

If I get one cut by a machine shop, anyone know the dimensions or how to get them? I doubt measuring with a tape measure would be accurate enough.
