Well i hate my test pipes so after 3 days im taking them off. But i noticed that on one of my cats the honeycomb seemd to be loose and move on the end that bolts up to the y-pipe i dont think this is normal but figuered i would check.

Sucks just wanted to go back to stock and sell now i have to spend money to go back to stock.

 

Yes, that can happen to the stock cats. I've heard of it happening to a few other people too.

 

and when that happens...???

happened to me

 

What didn't u like about the test pipes?
