Hello

I own an 04 350z.

I was wondering if heatshield is required for aftermarket headers.

thanks in advance.

 

no

 

Are you speaking about wrapping the headers?

 

Nope. You can even take the heat shields off of your stock headers if you'd like.

 

No you don't "NEED" the heat shields; however, there are benefits the insulating the headers so it's something you should definitely consider.

 

When I ran crawford headers (with no heat shield), during track driving they got so hot it burned through the rubber EVAP line (lucky it wasn't the fuel line eh?). I took the headers off and went back to stock headers.

During normal street driving, I could feel the heat in the interior of the car.

 

wrap the headers with exhaust wrap

 

hrm. . .were your headers coated or wrapped. . . ?

 

My Crawford are coated and still produces an EXTREME amount of heat!

OP, keep the heat shield if you can... I couldn’t - absolutely no room... when I have time I plan to take the car to TS and see if they can somehow fabricate heat shields.

 

thank you all for the great insights!

i have now less things to worry about ~_~

p.s. can anyone give me a link to where i can purchase the wrap?

 

Heat wrap is popular with drag racers. Run the car 13 seconds. Return to the pits and shut it down.

Consider a daily driver with heat wrap. 1 or 2 hours on the road. The manifold will get hot and stay hot. What do you achieve?

I don't go to track nor do drags at all.
I just do daily driving.. max at about 2-3 hours a road in twice a month maybe.
all other times, it's less than 30 minutes of daily driving everyday.

 

in that case I would suggest not even bothering with headers much less managing the heat from them.

 

Go with jet-hot coating.

They offers many diff coating. I rather choose coating over wrapping the headers if my car is DD.just my two cents

I've been running ceramic coated Stillen headers without heatshields on my DD, and have not had any issues.

 

ive got dc headers with ceramic coats. (found out last week at my buddy's shop) so i should be all good. rite? haha..

next time, i am just buying a stock car and doing it my own. too much hassle to find out everything about it.. -_-

 

You should be fine. Just keep ur eyes on once a while.
