Howdy all!

So I recently purchased my 05 AT TSX with about 90k on it and today it sounded as if the muffler became detached and sure enough, the catalytic converter and midpipe (?, sorry im a newb forigve me if I'm using the wrong terminology) were no longer attached. I checked it out from underneath, thinking I would only need a new gasket and some new nuts. Turns out the bolt threads are almost completely stripped, leaving me in the market for a new Catalytic Converter. Does anyone have any suggestions on which one and where I should buy it? I have looked on rockauto.com and a couple of other random google sites. Also, is there a DIY thread for what I'm doing? I tried searching the site and through google but was unable to find one

Thank you in advance!

If you have damaged bolt threads on catalytic converter studs, it may be possible to replace stud/s by knocking out old stud and pressing in new.

Even if stud is welded in place it may be worth paying someone to replace the stud. A new OEM cat is costly and worth some salvage effort.

Any video on Honda/Acura catalytic converter replacement should provide some guidance.

You will need to elevate front and rear to have adequate working room. I used front ramps and rear jack stands.

Here's one example:

good luck

Bolts/studs are welded on there, how much would it cost to have them taken out? I appreciate the quick response and also another quick question, do i absolutely need OEM or is it safe to buy another brand? Thanks again for your help!!

I've never heard anyone say that aftermarket converters are as good as OEM. Problem is OEM is $$ ($700). That's why I suggested trying to salvage. Repair (if you supply studs) should be $ $25-$50. I believe the studs are pressed into a hole and then welded to hold in position.

good luck
