Hey guys I want to start ordering my exhaust parts today or tomorrow I just can't between TPs and HFCs. The only reason I would want to do HFCs is hoping it would pass smog here in Cali and I don't don't have to remove them every time for smog. If not then I rather just get a TP more power louder exhaust.... only bad part about it is the smell of the TPs is it bad? The exhaust I'm getting is the KCR (hks replica) testpipes I only thing I would go with the res Megan TPs. But when it comes to HFCs I don't know much could you guys please help me.

 

Anyone?

 

i think they're both illegal in cali, no? Berk's HFC might pass... I'm probably wrong though...

 

Yea they both are bro I just wanted to know if it will pass smog I'll get it if not then I rather just go with TPs

 

BERK'S HFCs will pass the sniffer test no problem it's the visual where you might have an issue. Where I get my test done they don't care about the visual as long as it passes the sniffer, quite a few places are like that. Test pipes in CA. just isn't a good idea since our state has started roadside tests just like the DUI stops. They can test you driving by if you don't pass they'll pull you over and find out why....see not a good idea to have test pipes!

Thanks Gary I think I will go with the hfc the smog place I go to are the same way they wont look just sniffer test. How does it sound???? I know most people say the quality is awesome on the Berks products.

 

The only drawback with Berk HFC's is it makes hissing noises like you got snakes in your car. I'm gonna be getting some different catalytic gaskets to fix this problem. I hear it is resolvable from Gary. Felt a great improvement in power after I put on the Berks. I really like them.

 

Let me know if the gaskets do help because after reading a lot I decided to got with the Berk HFCs hopefully I'll pass smog

 

When I installed my BERK'S I bought new OE gaskets from Nissan cause I didn't like what came with the HFCs and I have zero hiss. They're not cheap but I dislike the idea of doing a job twice.... If you do buy new OE gaskets match them up with what BERK sent you, Nissans information is incorrect in their system.

Is the oem gaskets really better than the berks? To remove the hissing noice? And how much are oem gaskets?

 

I was in a hurry and reused half eaten up gaskets, no hissing even with a little leakage, I then had them properly sealed up and still have not heard any hissing. I don't know why. not complaining either haha

 

how will they know you have test pipes by driving by you?

 

Smell of the Raw trail of spent fuel left behind you like a vapor trail lol

 

i have the megan resonated test pipes and there rasp after 3k rpm...im prob going to switch to motordyne ART pipes..if u go with test pipes just go with the ART pipes from the beggining
