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

 

1. no
2. no
3. no
4. Hard to say.


I know hfc with nismo sounds great. My resonated test pipes with the nismo sounds great. I'll try to get a vid up.

 

^^
I've been wanting to hear a Nismo exhaust with resonated test pipes.

 

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.

 

yeah i was looking into the Berk HFCs... i really like the price

im also considering the Fast Intentions, Crawford, or Ultimate Racing cats...

im a bit timid however to pull the trigger, considering the cracking issues

 

Yeah HFCs are my first choice over TPs...

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...

 

i have HFC and Nismo and it sounds GREATT nothing but compliments and i have no cracks yet (Crawford HFC/ Nismo exhaust <--5000 miles)

 

Ive had my Ultimate Racing HFC and nismo combo on for about 18,000 miles and have loved every minute of it! Ill get a video up either tomorrow or the day after.

 

Please post up a vid!!!.. im gettting my resonated test pipes soon

 

1. No. Just buy the HFC's, you will not regret it at all.

2. I had no problems with my HFC's and Nismo Exhaust

3. ^

4. I purchased the BERK ceramic HFC's and have had no issues.

 

If you want high-flow catalytic converters, I recommend a mounting bracket similar to above.

 

can you please provide a little more info? where to get that bracket? what point to mount it? etc.

do any HFCs already come with brackets like that?

 

some test pipes/HFC comes with it. You can't simply just add it on. It can be welded if you find some brackets but that's highly unlikely.

 

Davidv must enjoy sharing his pictures because that's like the 59th time I've seen that test pipe.

 

+1

 

i have nismo exhaust with Berk HFC. No problems so far

 

Ultimate Racing HFC have mounting brackets. I def. recommend them; got em at Z1

 

LOL. That's my favorite photo.

 

A test pipe weights about 2 pounds. Its OK to let it hang unsupported.


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.

 

hmm ok.. i wonder if my buddy can fab me some supports while installing them... thanks for the info!
