Long Tube Header Install - 370Z/G37 Detailed DIY

This video is a detailed DIY on how to install long tube headers on the VQ37 engine in your 370Z or G37. Long tube headers are an excellent way to improve the sound of the exhaust note, decrease the weight of the car, and increase peak horsepower through the concept of exhaust siphoning.
This install is not for the faint of heart, as the bolts holding the header to the engine block are very difficult to access. This is not an install for anyone who hasn't worked on their car before. With the right tools however, and following the detailed steps in this video, this project is more than doable.

quick question - since I believe you are in the DFW area - does the LTH pass emissions without issue? Was there anything special you had to do to ensure it passed inspection.

@thecarizon504 4 года назад

I have been running test pipes for two years. It will throw a code for the cats which will cause you to fail inspection, however if you get the car tuned they can turn the circuitry off that checks the o2 limits. This means the car won't throw a CEL which is all the inspectors really look for.

@@thecarizon504 yeah my bad. the video is capped at 360p so it looked just like a torque wrench. and where did you get the flex head breaker bar?

How much horsepower did you gain from this install?

@thecarizon504 2 года назад

I didn't dyno before and after the test pipes but it's not unreasonable to assume maybe around 10-20 if replacing the catalytic converters. As much as 30+ if your car hasn't been tuned yet and you go for an aggressive tune.

Yo, what the fuck? My block does not have empty thread locations for the repositioning of the studs????

@ThatRedNismo 11 месяцев назад

It turns out that on pre 2014 blocks, you don't have to change the studs around. I'll make a video on my installation soon.

@juvenalgonzalez782 2 года назад

Do not try to take them off with a 3/8 that will make it hell seriously I had to weld 2 bolts to get them off and to do that I had to slide the headers with my sawsaw

Great video. Sub from me

@marshalsiler6580 2 года назад

Don’t unplug your battery if you have a tune! I was the idiot that did that :,)

Why not

@TBR972 2 года назад

Just for ~12 hp in this case don't worth it. But nice vid 👍

@slipknnnot 4 года назад

This is more difficult than the differential install and clutch ?? tf ? ???

@thecarizon504 4 года назад

The clutch install was more time consuming but these bolts were harder to get to.

@Spushed 2 года назад

So basically what you’re saying is, it is worth the $300 to have a professional with all of their appropriate tools to install at the very least the long tube headers. LOL

@etejeda1984 Год назад

I dont know of any reputable mechanic that would do this job for $300. Please send me his info if you know of one.

@Spushed Год назад

@@etejeda1984 it's a header install not a triple bypass surgery. I'd hate to live where you're at if they charge more... My fast intentions LTH and full exhaust install was less than two hours done properly. I know this as I was in the bay watching as it happened. So figure a touch more than $150/hour for the work seems more than fair.

@etejeda1984 Год назад

If you dont mind me asking you where and what shop you took it too? I have these coming in next week was going to tackle it myself but if its 300 or less to do the job I would consider it.

@@etejeda1984 do you live in the PNW? Mine were installed in 2011 over a decade ago. All I remember is that it was in Tacoma Washington.
