Installing Momentum Headers

SS_Firehawk · 02-16-2013, 01:13 PM

I'll say I told the shop to remove them before going ape $hit on the headers. They did, but I still had one go bad. Put too much pressure while you are trying to break it loose can just as easily damage it as the impact wrench. I didn't say don't coach them, but there are plenty of good mechanics looking for work that are willing to do it.

Hey chris, what tool did you use to get the last 2 bottom bolts on the passenger side?! Nothing seems to fit, and i really want to avoid using an open face wrench. I have the ratchet style wrenches, and the bolt seems like it is way to close to the header pipe to fit over it :-(

tall socket with a swivel head.. on a 3/8ths set. i actually think 1 of those 2 bolts came loose.... i need to get in there and double check it all tomorrow.

As much as I would like to agree, I cannot. Some of us (such as myself) had no garage, no tools, no ramp, no jacks, nothing to do this ourselves. Not only that, there are easier cars to learn on. I paid someone to put my stuff on. They never worked on 370's. I gave them advice from everyone here on the forums on how to approach some of the mods being done. I don't feel inferior because I was unable to do it myself, I'm happy I could afford to do it in the first place. And huge props to everyone who does do it themselves, but to say we can't be proud of what we have because we didn't, or couldn't put it in, I disagree.

Sorry to derail. I'm just rooting for you Alex. The headers are a PITA. It was a nightmare just trying to unclip my O2 sensor for troubleshooting. I spent 40 minutes trying to undo it and another 20 trying to put it back in. I want to see pics of the slayed headers and the new ones when your all done

Maybe make a pimp cane out of it.

AlexRaymond19 · 02-16-2013, 08:10 PM

ALL DONE!!!!!!!!!!!!!!!!! Its soooooooo loud holy ****! I think i have a small leak somehwere on the exhaust because i heard a little hissing noise. But it seemed to go away once it got a little warmer. I cant run car very long because its in my garage under my house and the fumes got pretty bad, so tomorrow i will put insurance back on here and do a proper test drive

With headers and test pipes some hissing is going to exist on deceleration. It's just the nature of the VQ. Now if you're hearing is an acceleration then there is a problem.

SS_Firehawk · 02-16-2013, 08:17 PM

Woot! CG's! Now to wait patiently for some header pron.

ts-c63 · 02-16-2013, 10:10 PM

Video video video!! I have to hear this thing cold start and fly bys !

AlexRaymond19 · 02-16-2013, 10:45 PM

Im uploading vids now, sorry no fly bys yet. There is still 2 feet of snow on the ground lol. I just have a cold start, some revs inside the cabin, and some about 15 feet behind. I will get better video tomorrow, and also throw up an album of all the pics i took during the project.

I still need to put the steering together, and somehow get the bar back on that supports the test pipes, but it does not line up right, will i be fine without it? Still have plenty of time to figure it out

You can run without it. Some HFC's and TP's don't even have support mounts on them. My TP's didn't line up very well either, I ended up bending the bracket to get it to work.

The hiss is really prominent, almost sounds like a cheesy supercharger or turbo blow off in person. I don't really mind, im just stoked its all done. And yes, mods can rename and sticky this thread as "why not to install headers yourself, unless you want to spend up to 20 hours of painful labor, about 100 bucks in extra tools, headaches, heart attacks, scarred arms, bruised ego, and cry yourself to sleep every night until the job gets finished" :-)

Huck · 02-17-2013, 01:12 AM

Hahahaha yeah that's pretty much the case.

The hiss is totally normal, I actually took my car to two different shops thinking I had screwed up and they did every test known to man. That's just the sound our cars make for some reason... Congrats on it being done!

And I didn't mean to come off like a **** about the self installation thing, I was thinking more of the super rich arrogant ******** that throw $100k at their car and then brag about what "they" did to it. I just like the sense of accomplishment that comes with doing things yourself, but I totally get that not everyone is able to do the same, nor does everyone have the time or the interest in doing it themselves. It's fine with me because that's how I make extra money!
