something in my muffler

[nasty281]

Just bought used kooks axleback and I noticed both axlebacks feels like someone put several handfuls of sand in each one. Seller said its probably just carbon build up from running rich. Does this seem normal I dont want to put a clogged up muffler or something on my car. Jw bc there is alot of it in the muffler. Sorry if this seems newbish

If they have not been installed, turn them on end and shake. See what come s out. 2 options. Contact seller for money back or contact Kooks about possible warranty!

Nothing will come out? Already contacted seller

Do you have access to some compressed air? If so, try to blow air through them.

I'm wondering if there if baffling in these mufflers. Maybe it came loose inside somehow??

Iirc he did have cats

FI cars have a habit of killing the cats which is why people recommend using the off road pipes; mine came off at the track and clogged my passenger side muffler, it was a mess pulling that junk from the muffler.

Probably some cat pieces, doesn't sound like chunks though from what you're describing.
Just some disintegrated cat material.

Seller boosted? Maybe his cat material stuck in muffler m

I bought a used mid pipe before and grenaded the cats. Clogged up my MAC axel backs.

Read some reviews and figured I collapsed the baffling rendering the mufflers useless so angered and instead of wasting time I just CUT the mufflers off.

I wish I didn't do that. Once they were off a bunch of substrate fell out of them. Live and learn I suppose.

Just never thought it was the Cats cuz I was N/A.

Try to take them to somewhere that has a compressor and blow them out. Chances are they're fine and just full of crap.

Or find a landscaper with a big backpack blower and get him to blow them out for you.

there was a member on another forum that had the same issue last week, said sand actually fell out of his Kooks, and he bought them used as well........

Um..........those tips are likely going to stick out far past the rear fascia. Have you mocked them up yet and noticed??
