WalkerExhaust 31384 Exhaust Pipe Flange Gasket

Used this as a flange gasket between my muffler and tailpipe on my 2004 4runner. It is not thick at all (2.5cm) compared to the standard of other brands (5cm) so I bought 2 and stuck them together. It fit fine and did the job with 2 and I have had no leaks or loud vibrations since replacing my exhaust. Great value for the money. If you are going to buy this I recommend you buy 2 because of the lack of thickness.

For my '93 Camry 2.2L sedan. Ordered two by mistake and they are very different from each other. One made in Mexico, the other in India. One has a rectangular cross-section and is fiber layered with thin metal mesh reinforcement. The other has an "eye shape" () cross section whose outside is metal with some kind of synthetic material inside. Both have identical ID and OD dimensions. The fiber version is 50% thicker than the second metal-jacketed kind. I seem to like the fiber one better, but I suppose it doesn't really matter.Curiously, the ID dimension is oversized by about 3/16 inch (5 mm). I don't expect this to be a problem since both pipes' mating flanges are 8.0 mm thick (5/16 inch) and the bolt holes can pass 1/2"-13 or M12 bolts. In comparison, the muffler-to-intermediate pipe gasket (Walker 31332) is the more usual perfect fit. These 31384 gaskets took over too weaks (; to arrive after order, though, so I'm not happy about that. "All's well that ends well" after it's all installed with a Walker 45275 "intermediate (exhaust) pipe" and a Walker 21181 muffler.

Bought two of these in conjunction with my exhaust system replacement. Both were sold/shipped from Amazon but came in two different thicknesses. I was in a bind to get it on the car so I didn't bother ordering a replacement, so far it hasn't affect the seal but we'll see if it leads to exhaust leaks down the road.

These gaskets will work if you are using them between two new pipes but are nowhere near thick enough if you are bolting between an old (rusted) pipe and a new one. I had to go to autozone and have them find a thicker one the same diameter and that worked great. I’m sure you can also double or triple these up and it would work too.

Fit my 2002 4WD Limited 4runner.

Perfect Seal.!!🙂

For anyone wondering the official thickness per Walker's literature, it's .09" or 2.286mm.I received stamped Made in India. Many Walker gaskets seemed sourced from the same.It does its job. Little pricey imo. Negative 3 stars for a horribly incorrect dimension thickness of .4 or 1.8 inches. You need to update your Amazon listing, Walker. This stuff matters when assembling an aftermarket exhaust.

Fit perfectly. I used this on the joints between the muffler and catalytic converter and the muffler to the exit pipe on my 1998 Toyota 4Runner (3.4L engine). You'll need two of these if you're replacing the muffler.

Can't wait to install all of the exhaust parts I got from Amazon.

Installed and functioning perfectly on my beast (99 4RNR).

Exactly what I needed.

Blew out (gasket came apart) within a couple days.
