If you want sound and some HP get the cbe. Hfc can break apart and clog your cbe. The 350z had this problem, so does the 370z.

Yes the cats can fail and clog up your expensive exhaust, seen it happen to the 350z and 370z.

Good question op, Well i would say the nismo z still sounds great. I wonder if the s tune nismo system would bring back that sound. Someone that has heard the s-tune should chime in.

Yes it is but that's not the reason why it sounds different.

Yeah. This happens rarely, if at all. Sorry.

It can happen with any car. I think it's more common on cars that are not tuned well. Too much unburned fuel collecting in the catalyst can lead to deterioration and eventually it will blow out.

It also happens to some OEM cats. One of the catalysts blew out on my girlfriend's CLK 500 when she hit 70k miles. Covered under warranty (OEM emissions system is covered to 80k per federal law).

Yes the G37 sounds almost identical. I saw your post where you put on a
g37 muffler, did you get the right sound?

Point is, any name brand cats are no more risky than factory, and a fail of a tune is the main reason, not the HFCs.

Wonder if the 350z exhaust could be retrofitted on the 370z? Realizing some cutting and modifications would be necessary.

I haven't changed out my non-resonated midpipe yet. I'll see if I have time this weekend to swap it out to resonated midpipes. I'll let you know how it turns out.
