Whats up guys. I have some Fast Intentions RHFC and JetHot coated DC Sport Stainless Steel headers. Took them off of my 2011 G Coupe (they fit the 370z also). They have roughly 1000 miles on them.

SOLD - FI RHFC - $550 shipped to lower 48 (gaskets for both sides and 8 bolts included, same as how it was received)

SOLD - JetHot coated DC Sport SS headers - $450 shipped OBO to lower 48 (12 header stud nuts and 2 bolts, same as how it was received)
Here are some applications, see https://conceptzperformance.com/dc-s...#compatibility for even more fitment options.

• 2008-2016 Infiniti G37/Q Coupe 3.7L
• 2009-2016 Infiniti G37 Sedan 3.7L
• 2007-2008 Nissan 350Z 3.7L
• 2009-2018 Nissan 370Z 3.7L

The headers are not the cheap metal ceramic coated, they are the Stainless Steel version I sent to JetHot to have coated.

I have more pics of both if people are interested I can post them.

Why I removed them...…. When I purchased them I was told they would be pretty loud with my CBE. So I opted for this route over the long tube headers which were to be even louder. After install, while loud, I did not find it overbearing so I decided to go for the long tubes as I was leaving some power and more importantly torque on the table. And I love the long tube headers so the header/cat combo can go.

Complete transparency, the DC headers are a PITA to install (mainly drivers side), due to the piping routing. Doable though and the right tools help. I am not a mechanic but I know my way around a tool box. There are scratches on the driver side header (see pics) from my fight with the steering shaft before I learned to remove the "C" clip also for even more space.

 

Interested in the cats. I have a 2010 G37xs. My stock cats are rattling, and need to be replaced. Couple of questions.

Would the cats work with stock exhaust?

Any CEL codes when you had them on?

Do I need any additional parts to install?



My biggest concern with going with RHFC are CEL, and yearly smog. I’m in Nevada.

 

I can add some input: these RHFC don’t throw CEL’s and bolt straight up to the stock exhaust.

8yrs with my RHFC w/ no issues. (Knock on wood)

 

Cool. Does it matter if it is a coupe or sedan? I have a sedan. Do you know if I will need a extra 02 bung? I was on the website, and one of the options is a extra O2 bung. I want to take them straight to the shop and install.
I got $500 for the cats. Will you take $500 shipped to 89144?

 

I can add my voice to that claim. 6yrs with my FI RHFC w/ no issues.

 

They will fit the sedan also. You do not need an extra bung, these do not have any extra bungs. You can get them with extra bungs when ordering from FI if you want them for monitoring. They come with what you need for the install. I am really shooting for $550 so after shipping and paypal fees I get about 500 off of them. If I am not getting any interest after a bit I will PM you and see if you are still interested. I never saw a CEL with them. Not sure about your emissions standards though as I don't have to worry about that where I am. I would think since they are still cats you'd be fine but I am not 100%. I'm sure that is in a thread somewhere around here.

 

Sounds good. Thank you for the good feed back. Hit me up if you are unable to move at $550.

 

I'm interested in the cats for my 2012 G37s Sedan. Do they come with everything that they originally shipped with? Like whatever manual(s) or other information was included?

 

Yes, I have the install instructions that will be included. Also the break in procedure which is not needed but they were broken in properly. I can also include the license plate frame that came with them.

 

Thanks and is that $550 the shipped price?

 

Yes it is. I priced them like that to cover the shipping and paypal fees.

 

I'll take it.
