NISMO and HFCs...
I want my nismo to be louder and more mean sounding.. so i said ok ill get some HFCs... (i would love to put on some RTPs, but reading about the smell, rasp, rattle, and obnoxious loudness, turned me off of TPs)
Anyways, I thought i had it all figured out, UNTIL further research landed me on this thread: https://my350z.com/forum/showthread....light=cracking
... and others that talk about the nismo cracking...
So basically my questions are:
1. Is getting the HFCs for my nismo a bad idea?
2. Do the later/newer versions of NISMO exh have anything to battle this problem? (stronger welds, braces, etc.)
3. Is there anything i can add to the exhaust system to prevent cracking?
4. Are there specific brands of HFCs that will not crack with the nismo? (I think i read that the Crawford HFCs had the most problems)
Thanks in advance

I've got the NISMO...
exhaust and plan to add the Berk HFCs w/ the NISMO headers I've got sitting on my floor haha. I am sure I saw another with a similar set up. Not sure what else you're running but also rawking the MD 5/16th spacer and NISMO CAI.
I've heard nothing but good things about Berk HFCs...if that helps.

im also considering the Fast Intentions, Crawford, or Ultimate Racing cats...
im a bit timid however to pull the trigger, considering the cracking issues

I would love to hear your set-up though.. I know TPs give decent gains and i would love some more power, BUT everyone here says they are way too loud, they smell and they rasp...

do any HFCs already come with brackets like that?

Above Kinetix high-flow catalytic converter with no support bracket.
High-flow catalytic converter is a different story: about 5 to 10 pounds. Something has to support it. Usually the exhaust manifold and exhaust pipe.
