You have a crystal ball? Man I would like to borrow that for a day or two!

 

In other words if they have been running them for years and years on dozens of very fast 4G63 motors and have never had one crack and offer lifetime warentee against cracking it will never crack, Right???

Geez man, what else you need.

Bring it Biatch

J/K

 

lol you tell him guack!

 

The lifetime warranty sounds nice, but as a consumer, I'd like to see some hard test data that backs up the claim that these manifolds will never crack. I'd like to hear that someone has over 50k miles on his manifold that drives in everyday traffic going through sh!tty roads, track days, etc. Basically, I'd like to see how the manifolds fair through the torture test.

 

well here is a start i got 10k on mine and i drive in la heat stop and go traffic , i drive hard in the canyons and still do alil drag racing. and um no cracks leaks spots dings nicks nada nothing zilch. only time will tell but the tubing on this manifolds is like tank armor = )

 

Yeah, i wasn't even worried about wear when i started this thread....just performace, really. I've heard they crack, I've heard "Mine is old and did not crack"....who knows

 

well performance is awsome quick spool on gt35r, the headers has lifetime warrenty so that is sayin alot specialy since ive picked up the header its some massive thick tubing = ) , my bets are i wont have problems but that is my opinion = /

 

For those of you who are going to tubular manifolds, if you would like to sell me your stock manifold/O2 housing let me know....
