I wanted to install these headers on my 2004 G35 Coupe,

I was wondering how much time it would take to install these or how much I should expect to pay to install.

 

pick some shitttier headers will ya

 

^^^^ haha

 

If you want problems later, sure go ahead.

 

What are some good headers in your opinion?

 

"Welcome to Driver!" Headers on your VQ motor are a waste of time and especially $$! If you'd take your exhaust system apart you'll discover most of the restriction is in those OE cats. Replacing them with HFCs (high flow cats) gives you an automatic 8 to 10 WHP, much better than the 3 to 4 maximum WHP you'll get from adding (good) headers! You're new here, read all the sticky at the top of the coupe page and use our Search function if you have questions...Gary

 

I have a full stillen catback exhaust on mine already, but thanks for the tip.

 

he recommended u replace the stock cats. ur stillen exhaust system stops at the catalytic converter. so ur still running the oem stock cats, which are quite restrictive.

if u were to still wants headers, stillen and dc sports make decent ones. not worth the money in the end though
