First time buying an aftermarket exhaust

Bought an MBRP Street catback, I was just wondering if grease on the end of the h-pipe (connecting to the cats/mid-pipes) is normal/okay?
I can understand it on top of the h-pipe to help with squeezing it into the factory mid-pipes, but should I clean the large amounts of mustard-looking grease inside the h-pipe along along with the visible metal shavings?
Or am I worrying too much. :headbonk:

wtf. my exhaust was basically clean, i think you got dud. I'm sure it still works if you can clean it up but they shouldnt come like that.

Seriously? I ordered it directly from MBRP, weird

That's just the grease from forming the pipe and the reduction. It'll burn off no probs. or clean it if you like.

Ok, cool, thanks!

Someone forgot to run it through the cleaner it seems.

See what it tastes like.

Put it on and forget it.

I would clean it all off before installing. You don't know what kind of reaction you'll get when you expose that crap to red-hot exhaust gasses. It may just burn off with a stink or it may ignite...maybe even mess up your cats. I'd clean it.

Your mid pipe had a case of the clap.

Yep, I would not want that garbage in there but that's me. If it was 100% harmless then every set would have this in it and no one would be complaining. Obviously it's not normal to see it, so I'd remove it.

I ended up cleaning as much as possible, I don't want that shit especially the shavings flying around in the mufflers.

You should contact mbrp for a replacement/refund
