It's muffler time

I blew apart the mild steel muffler on my NAS 94 D-90. So it looks like I'm going to have to replace it. The price of the OEM muffler is outrageous so I'm looking for aftermarket.

When I crawled underneath to examine what was going on, besides the big f'ing hole I found, I saw one of the cats had been replaced already by one of the previous owners. I'll guess that more than just the cat was renewed because all of the pipes in and out of the muffler are fine with no signs of rust through or even softness.

I'm thinking of just replacing the muffler and not an entire cat back system. Business sucks and I would rather not spend more than I have to (but getting a quality part is a must). I'm leaning towards a magnaflow and to that end does anyone have a part number for just the muffler?

Also, is there any reason why just replacing the muffler is not a smart move?

Thanks,

Eric

Last I checked you just go on their site and say what make, model, year you have and it tells you everything.

I had the local shop weld a Magnaflow into the Disco.

Got the handy dandy tape measure out and figured out the longest one that would fit...cut the old one off and welded the new one in.

No biggie.

x2 the maganflow SS universal replacements are cheap and easy to get. Come in every in/out size under the sun.

performancepeddler.com has good deals and so does amazon


check magnaflows site for a part number after you measure the pipe diameters and go nuts

Does your current setup have bolted connections at the muffler? If so, you will need to either cut these off and use slip connections/clamps or weld in the replacement muffler. I went through the same things you are a little while back and opted for a Flowmaster because they have an "offroad" series muffler that takes a little more abuse because the case is made of almost 1/8" diamond plate. I chose to buy two Walker connectors (41723 & 41726) for about $10 each to weld onto the muffler to re-establish the bolt in connections.

Muffler Replacement

What bolts did you use to secure the muffler flange to the cats and tailpipe? Were there springs involved or just nuts and bolts?

Thanks,

Dan
