Install the hole system and jsut check the cat during oil changes. if they crack Berk will send you a new one.

 

Yeah there's always that option. I guess I just have to deal with it since it was my decision to go with this setup. I might go get it installed today.

 

Test pipes + Nismo: http://www.garaget.org/video/33clyhay1of2

Sounds wicked.

EDIT: He has headers too.

 

my berks cracked with STOCK exhaust... whats even more interesting is that they cracked right where the support bracket is attached to the pipe

 

Interesting. That just confuses me now.

This is what I though prior to reading your quote:
When I installed my Nismo exhaust and Berk HFC and when I got to hold the stock y-pipe, the first thing that jumped at me was that the stock y-pipe has significantly better located flex sections than the Nismo y-pipe. They flex very smoothly and I could understand Nissan put them there to prevent stress on the cats or the engine in general.

But compared to the stock y-pipe, the Nismo y-pipe has poorly located flex sections that do not allow the cats to move up or down. They can only flex left or right...

But I just don't know what it is now. Oh well, it sounds bad@ss!

 

does it rasp at all in the higher RPMs??

 

No. I don't know what your definition of rasp may be, but in my opinion, it does not rasp. Even if it does, it's not much. You wouldn't believe how many comments I have gotten since the install. No regrets here man.

Here's my sound clip:

youve been asking about this setup for a long time now. glad youre enjoying it

 

I think my setup cracked today going to the exhaust shop just to be sure but I hear a rattle sounds like its from the HFC's.

 

i've picked up the stillen engine dampener to help with the engine movement.. i wonder if this might help with the cracking.. im currently running some helix test pipes (WITHOUT the support brackets) and the Motordyne XYZ pipe... we'll see what happens.......

 

Getting some Test pipes soon (Megan) Can anyone tell me what I
ll need to avoid getting a CEL code ? (Searched , too many options)

 

non foulers... the end.

 

Got em!!, hmmm jury still out .Part of me loves the sound but hate the fact that I can't be low key anymore ...hear me coming a mile away!! I'd post vid but don't know how.... anyone want them if I change my mind ...(for a small $?)

 

You are not low key even at like, 3k rpms anymore? You're always loud now? What about just normal light cruising?

 

nope , louder period. low rumble to 2k then LOUD dronning till about 4k then just hmmm? SEX? Can't really light cruise anymore . BTW ,Pop charger , Nismo cat back, so stock might make a difference. Love and hate really.....just waiting to get pulled over. o yeah..300 miles and no Cel CODE.

 

^^really?

anything below 2500 rpm is QUIET for me

like....way quiet. quieter than stock quiet

 

What mods do you have ??? quieter than stock....? Really?

 

Just let me tell you guys, my nismo and megan V2 resonated test pipes combo sounds amazing! very little to no rasp and they have the new flex section in the test pipes to prevent cracking. For only $139, the investment is WELL worth it

 

Update. My new Berks with brackets are doing fine. Only problem is I just found out my Nismo mid-pipe is cracked after the resonator. Guess I need to switch to one of the other y-pipes?

 

any of the guys that re welded their cats after being cracked had any success. Have they lasted after being fixed???
