The Random E46/ZHP Question Thread

That looks like it rusted through. Probably not too much force to break it.

It... doesn’t sound good

Had the same thing happen to my mom's Corolla. There might be too much rust to re-weld that seam, so you may have to have a small length cut off from each side, then have a small length of replacement tube welded in. Might be a good idea to spray-bomb high-heat spray paint for further corrosion resistance

Yea that definitely needs to be cut and a new section added. Still a simple enough task for a competent muffler shop.

Also +1 on the high heat paint. I sprayed the X3’s muffler (purely for aesthetics, not corrosion resistance) back in 2014 with the Rustoleum “BBQ high heat” matte black and it has held up for 6 years just fine.

I was definitely surprised that the weld was never covered, rest of the undercarriage is fine but having that exposed metal was just like a magnet. Wish I knew the first thing about welding lol

Will definitely be going the route of the high heat paint.
Any chance anyone knows of a temporary fix? Currently the muffler is hanging at 45°. I know i can’t just yank it off because it’s bolted on and not sure if i want to deal with the sound for the next week

You could try one of these sleeve-style band clamps. I’m not 100% convinced it would work, but that’s the best temporary solution I can think of.

Oh right on, my local shop has it in stock too so I’ll definitely pick that up. Seems like good overall reviews, just can’t imagine the seal being perfect.

Are the OE headlight bulbs 5500k?

Local parts shops will also have exhaust seal tape for this exact situation. You'll want a lot of it lol
