SchwarzeEwigkt Posted August 12, 2010 Share Posted August 12, 2010 The flanges on the pipe after the cat and the one before the exhaust disintegrated. I see they sell flange repair kits, which seem to consist of some cast thingies that bolt on over the pipe, effectively a bolt-on flange. I was going to clean up the pipe and get some of these (or a piece of flex pipe and two exhaust clamps), but I don't know the pipe OD and the car's not accessible at the moment. Anybody know offhand the outer diameter of that pipe? I'm pretty sure it's 2", but the Internet hasn't been useful getting me that info. Link to comment Share on other sites More sharing options...
Legacy777 Posted August 12, 2010 Share Posted August 12, 2010 It's likely 2" or 2-1/4". I can't say for sure, but it's likely one of those. Link to comment Share on other sites More sharing options...
idosubaru Posted August 12, 2010 Share Posted August 12, 2010 i brought a friends car home this morning that needs the exact same repair - he's right it's either 2 or 2.25 but i can't recall which either. There's a dozen ways to skin this cat: Diameter = circumference/pi or circumference divided by 3.1415. You can take a tape measure and measure the circumference. Sometimes parts stores, particularly the good ones, have mic's on hand and i've measured exhaust right in the parking lot. You could call and ask your favorite stores and see if they have one. Or, you'll have to cut the old flanges off anyway to install whatever replacement you're going to install. Measure the diameter or take them with you to match up. Ebay often has exhaust parts for sale - almost always - not sure if they have the dimensions listed on there? Rockauto sometimes have dimensions of parts too. I wouldn't use the flex pipe, that stuff rots out in a matter of months. I'd get either real pipe or the bolt on flanges you're talknig about, those sound like a great idea, Ive never seen those.

subaru360 Posted August 12, 2010 Share Posted August 12, 2010 The split flanges I use are labeled 1 7/8" - 2" The actual OD of the pipe is just slightly more than 1 7/8" Link to comment Share on other sites More sharing options...
idosubaru Posted August 13, 2010 Share Posted August 13, 2010 The split flanges I use are those typically at any auto parts store - i've never noticed them on the shelves before? i don't spend a lot of time in the exhaust section though typically.

subaru360 Posted August 13, 2010 Share Posted August 13, 2010 The autozone here carries them, some of the other stores too. Link to comment Share on other sites More sharing options...
SchwarzeEwigkt Posted August 17, 2010 Author Share Posted August 17, 2010 I was able to get over to where the car was to get everything fixed (after fixing my sister's car AGAIN. Stupid Chryslers...). The OD of the exhaust pipe is 2", or rather a tiny bit less than that. Die grinder + cutoff wheel + 2" ID exhaust patch pipe + 2 pipe clamps = WIN.
