Well after 1 year almost to the day with Nismo and UR Cats the Y pipe finally gave way:





FAIL - enough said. Anyways I replaced it with a JIC Y-pipe and well see how long this one lasts.

 

I will be receiving my Berk HFCs tomorrow! I have had my Nismo exhaust just sitting in my room for over a week now. Installation comes Friday or Saturday! I will have support brackets too, so they should refrain from cracking.

 

My nismo cracked my berk HFC and other testpipes i've ran

 

But there are members that are running this setup and have not cracked their test pipes/hfc.

 

The Nismo is definitely not a friendly exhaust for HFC's. Two different brands of HFC's have cracked on me within 3k miles of bolting up to the Nismo.

 

the nismo sucks, I dont understand why anyone would buy it. It seems like the exact same thing as stock? When I was in the market for exhaust it was at the bottom of my list. Am I missing something about it??

 

looks classy, sounds good, nismo part, perfect if ran on a car with stock cats. Also some have warranties through the dealership with their cars.

 

Is the damaged y-pipe from NISMO?

 

oh, I can agree with that, however I couldn't tell any difference sound wise from stock.

 

you havent been around long enough to know but the nismo exhaust is notorious cracking test pipes, hfcs of all kinds.

 

+1 and used setups can be had for next to nothing. i enjoyed my brief ride with the nismo exhausts.

 

I just posted this question on another thread but since this thread is similar I'll post it here to.

I'm just wondering about the nismo cracking problem and instead of a flex y-pipe wouldn't something like the Ingalls "Stiffy" Engine Torque Damper work better by causing alot less engine flex?

 

No Nexx I have seen the threads and the countless complaints. I have been here long enough to know that. Just because your post count exceeds mine does not mean that I know nothing.

I do know I am taking a risk with this setup, but aahh what the hell. All I can do now is hope for the best.

 

nismo exhaust ftl

 

I think its the Nismo y pipe that is the cause for all the HFCs cracking isn't it?

 

I have my Nismo exhaust and Berk cats sitting in my room. I need to find out what exactly is the problem that causes the cats to crack.

It could be the Y-pipe. If I keep the stock y-pipe, do you suppose that will help keep the cats from cracking?

 

that definitely wasn't the problem for me. my flex pipes cracked so i bought and put on a stock ypipe, then one week later, my test pipes cracked. All i can say is that it's well worth it to have testpipes/HFC with the nismo though. The sound is so amazing. I get countless of compliments. Just make sure you have spare oem cats so you can ship in your test pipe/HFC for warranty work when they do crack.

 

Yeah i'm pretty convinced it's the nismo y pipe that is causing the issues - just doesn't seem to flex enough. I was also aware of this when I got HFC's I'm just surprised it was the y-pipe that cracked and not the HFC's.

Anyways Nismo sounds like stock but a bit deeper when your getting on it - and with HFC's it really wakes up. But it's still not obnoxiously loud or raspy like others - I was looking for a mild but better stock sound and I beleive this setup does it.

 

I just noticed something. My Nismo y-pipe has a some sort of a support tab right in the same place where the OP's y-pipe cracked. Interesting. I believe I have the latest edition of the Nismo exhaust.
