01 Passport muffler.

I have a sound coming from my muffler and i thought it was a heat shield but it is actually something inside the muffler. I have to replace it so is there any advantage to getting an oem one versus a muffler shop one??? Are there any sensors at the muffler that may give me problems???

i just read that it has 2 converters, would there be any good reasons to have "duals" put on it???? any gain in gas mileage by chance??

stay away from OEM mufflers. They cost close to 500 bucks.

The only advantage to OEM mufflers is that they are quiet (if you like it that way). If you want a little sound and some performance gain (not a lot but some) you can get a flowmaster 50 series SUV muffler. I have one on mine and its not loud at all but has some sound too it. I had them do 2.25" pipe from the y-pipe back (some guys do 2.5"). There really isnt a way to do a real dual exhaust on these because the gas tank takes up all the room on the left side.

i talked to a guy at my local muffler shop and he said he could replace it with a universal muffler and weld it all in for $80 plus tax. I also have a leak towards the front of the vehicle in the exhaust that he said he would also fix for that price so i didnt think that was too bad. I may look into the flowmaster, thats what i have on my truck..

Sounds like a great deal. Just make sure you have him put in a flowmaster and not some cheap 10 buck muffler.

Wow good price! I got screwed by meineke, they charged me over $400 to install my flowmaster which included new pipe to the y-pipe and bending the new tail pipe. At least they used stainless and its all mandrel bent.
