Pairing the Berk HFCs with my stock Nismo exhaust really increased the "growl" of the engine, especially between 4k and 6k RPMs.

It still didn't provide the full sound I was looking for, which I got later by installing the Berk CBE, but it did compliment the Nismo CBE well.

Yep the HFC with the nismo exhaust sounds a lot better and really howls when you get to the upper RPM's. Got mine from Kyle at IPP, great deal and awesome customer service!

There you have it....From a Nismo owner himself!!!! :tup:

WooHoo, that's what I'm looking for ;)

And as Matt says, if I need more I'll add a CBE later.. Once I've sold my other kidney to pay for it LOL

I've got stock NISMO with GTM test pipes...still unimpressed...someone was posting this set up with a muffler delete and stock resonators in place (video to be up soon, I hope)...otherwise, I'm looking at maybe putting two magnaflow 6" race cans on the rear to keep drone down but give it more grunt...I hope...

Got my name on the list for this group buy, hope to have order in on Friday :)

i installed CNT resonated test pipes last week. they DID NOT add any kind of growl. they did however make my car sound like a jet at take off. neat sound, but not the throaty growl i was looking for.

I second that bro, I have the F.I. Non res test pipes on my Nismo, and it's still painfully quiet.

Really?? I found a few clips on YouTube of Nismo exhausts and Berk HFCs, they sounded pretty good.

I thought test pipes would be even louder, since they must be less restrictive??

The Nismo exhaust does a really good job of keeping things quiet. The test pipes do make an audible difference, but it's nothing like changing the entire exhaust. For example with the windows up and the radio on an average level I can't tell any difference, only with the windows all the way down.

I just installed Berk HFCs in my Touring and I cannot be happier. You should call theZstore because even though they initially had them out of stock, all I did was ask for them to order them and they arrived in 2 days. The install is a bit tedious and can be very difficult but the results are worth it; a noticeable bump in power even with the stock cat-back and the sound level remained relatively similar at low rpms and cruising but really opened up in the top end.

Great sound clip :tup:

My cats have shipped, so looking forward to the install.

It sorta depends on your definition of "loud". To some, Nismo CBE + xx brand HFC/Test Pipes are gonna be loud, to others it'll be quiet.

If you want every pedestrian in earshot to turn their heads when the light turns green, then the Nismo CBE is not gonna be part of your ensemble of exhaust components....with or without HFCs/Test Pipes.

Well decided the HFC was not going to be loud enough LOL, so I did add an Invidia cat-back to my ensemble.

I'll update with pics after install.. and maybe a YouTube video if I get round to it :tiphat:

Nice! I rode in another member's '09 Z with the Nismo cat-back exhaust and it was really surprisingly quiet. I felt like it sounded great down low but got quieter as the revs increased, and I can easily see how a HFC would not really open it up a huge amount more. In fact, I thought that my '10 Touring with Berk HFCs and a Tanabe Y pipe is 2x as loud as a Nismo CBE.

In for videos!
