3" Dynomax Ultraflow Carnage

Interesting!

So far the 2.5" Dynomax ultrflow's on my Duster have held up just fine, they've been on there for well over 10k miles now. Guess I'll have to keep an eye on them. I love those mufflers, hopefully they hold up.

I know that the Summit turbo's that came with the Summit 2.5" system I have on that car only lasted few months before they blew apart at the crimped seams, pretty much in the same place as those ultraflows in the picture. I though that was weird, but I guess it's a more common problem than I thought.
