I've noticed a "tick" on my 280 with a 6 to 1 header. Got my hose stethoscope and found the area is under the flange between #2 & #3. My question, should I try tightening the nuts while the motor is cold or hot? You guys know more about the science of metal microstructure than me so please advise. Thanks for any replies. Cliff

While working on the 72 240z last night I noticed traces of blue paint on the 3 into 1 header flange where it bolts to the head. My father in law put the headers on in the 70's I'm guessing and I'm just curious what brand they are. Anybody remember whose headers came painted blue?

Having a bit of fun comparing muffler sounds on Zstory Race/Sport system with centre resonator 1 2

To duplicate a post I made earlier on the UK site, I’ve been having a bit of fun doing back to back tests and learning about making YouTube videos - my kids want their own Minecraft channels, so I’m trying to learn with my version, I call it Zcraft! 😄 Ever wondered what an exhaust system would sound like on your car with different mufflers? I personally found that the internet was full small clips but very little in the way of back to back comparisons on the same car. Well, purely for your benefit, I sacrificed myself!!!! I will splice parts of these together one day when I get more time, so that the same bit is played back to back on o…

Probably a dumb question: Does this material need to be ground down? The header was mounted like this for who knows how long. Any header I have seen has a flat mounting surface.

Finally going to redo my exhaust to gain clearance - remove resonators , add performance cat , and all new pipe from to back to front Besides the awkward and painful positions to do exhausts without a 6ft lift , I kind of enjoy crafting an exhaust system . I just buy and bunch of mandrel bends and pie cut what I need . Dual 2” gets tight :-0 Starting the first leg getting to the cat . Might challenge myself to TIG it

I am knee deep in the middle of restoring my '71 Z and on a hunt for the center resonator for the stock exhaust system. As of now I have the JDM Car Parts downpipe and repop of the original muffler, but its the bits in between that I cannot find. Has anyone came across a close alternative to the Nichira resonator? I have looked across the internet for one that's close but they are either too wide or too long to fit in the trans tunnel. I have one with me that measures roughly 6" wide and 12" long on the canister. It's not useable unfortunately. The best packaging resonator I have found available is one that is round in canister shape, opposed to the oval shap…

I finally ordered a MSA 3/2 coated header and 2.5 inch aluminized premium exhaust. I've read up and watched some videos on installation and think I can handle this job, but I've never done it before. Any tips/tricks are appreciated. One question I have is does the stock heat shield fit back in place without any modifications? Thanks everyone.

Has anyone used their coated 3/2 header? I've asked them if the tubes are of equal length, and they said they don't know, which is odd. Anyone know anything about this header? Header Exhaust Ceramic Coated 240Z 260Z 280Z 70-76 | Z Car Depot Inc Thanks.

Last year we bought a 1978 280z from a neighbor for our sons first car. It had been our neighbors sons car and had sat in her garage for the last 11 years. We've spent the last year getting it road worthy (new fuel lines, relined the tank, new suspension bushings, all new fluids and spark plugs, new tires/wheels, got the lights and blinkers working). Finally went to register and get emissions. And boy did we fail. HC at 977 (limit of 400) and CO at 7.28 (limit of 1.5). Also, the gas cap didn't seal. We knew it was likely to have problems, but seems pretty bad. The previous owner had lived where there were no emissions tests and was a high school kid, so he did a coup…

Hey guys, new here. I did a search and still no positive answers, hopefully you can help me out. I have a stock USDM 73 Datsun 240Z and want a Fujitsubo Super EX header/ Legalis-R muffler. Problem is no one on this side or the other side of the pond can figure out if there will be fitment issues. I understand that the header might not work because of the steering rack, but will the muffler work? I have contacted Fujitsubo japan and also many other tuners and no one knows the answer. And maybe someone came across a selection exhaust for 6.7 powerstroke share your experience please One tuner did suggest that since it was built back in the 70's that there wer…

Any insulation that can be added to the diff cutout area to stop the rattle? My exhaust is tucked up really high and is banging around. This pic is not my exhaust but just showing the area. Sent from my iPhone using Tapatalk
