Good video. about eights years ago I replaced the OE exhaust manifold with the pre catalytic converter on my wife's 2005 Nissan Altima as it had a few cracks in the case. I replaced the OE manifold with one made by Walker. That failed within two years still under warranty. I removed it and turned it in for a new one. Now it has been six years since I replaced the manifold a second time and it is leaking again where four tubes come together at the top of the pre cat canister. The car has 181K miles and I am not replacing the manifold again. I am going to try and weld it as you did.
Hello. Thanks for your videos. I have the same car. Everytime I look something for my car your videos show up. I have the check engine light on. The mechanic checked the error code and told me that the code is about the upper catalytic converter or the oxygen sensor on it. However the car has no problem when running. I guess when you have a faulthy sensor you should have other problems or symptoms. The car has 103.000 miles. Do you think the problem is the catalytic converter or the oxygen sensor? Thx
Love the video straight to the point not all complicated and harder than it should be keep up the good work thanks
Did you stick weld that manifold? What set up did you use to weld? Looking to do a similar repair
For those who want to find the leak in their exhaust, put a leaf blower in the tailpipe and tape it tight. Then turn it on and spray soapy water (Dawn and water) throughout your entire exhaust pipes and you'll see leaks right away because it will bubble like hell in those areas…
Great video. Voted and subbed. Did you install a new exhaust manifold gasket and gasket on the exhaust connection?
I need a new one. Just bought a 06 Nissan Altima and mine was glowing bright red today
How long did it take you to complete this project?
Made it seem so much easier than the mechanics out here.. Thank you.
Why weld when you can just replace the cat converter and flex pipe? Temp fix and gonna still cause issues later you think!
I have a 2011 Altima 2.5S with the same problem. How much should it cost to have this done by a garage?
All of us came to hear the sound…no sound
Awesome video. SUPER helpful
Great job!!!
I need to replace my block heatee i think am gonna hsve too pull off the msnifold and alternator too get too it unless if anyone has a better idea
Sounds are so important and I wish that I could have heard what noise this leaky manifold was making.
What material did uou used to weld it
Make sure you unplug the batter before anything !!!!!!
Was it making classic exhaust leak noise? If not, what did it sound like?
