With all the cracking issues I've read about with test pipes...with hangers, without hangers, I purchased a set of Titek test pipes that did come with hangers and they cracked in less than a month at the hanger weld.

Does anyone have issues w/ cracking of HFCs at all?

 

dunno, but my kinetix tp for the z held up like a champ for years and there was a warranty with it as well. I'd ask them if they have a warranty..

 

My FI Metallic Cats haven't given me any troubles thus far. They've been on for about 10 months, now.

 

ahero: what exhaust are you running? Apparently Fuji and Nismo mated to test pipes cause cracks more often.

 

he has hks i believe

 

Nismo and Fuji are notorious for cracking HFC's, testpipes and manifolds. We do have a few that have the Fuji - we've heard of no problems though. It's been months and months too.

Sorry, I didn't see this earlier. I'm currently pairing my cats with HKS.

 

Well, I'm in process of replacing my Titek test pipes that cracked. Getting a replacement set. I'm planning on keeping my Fuji exhaust, so I'm very hesitant on putting another set of test pipes on. Anymore Fuji/Nismo owners want to chime in?

 

I have had great success with the BERK HFC's. Never seem to have an issue. However i have had issues with some cheapy tawain stuff. Cracks at the welds. Also soon to come is the 2007 350z and 2007 G37.
