Great vid...your step by step style makes it easy for the non mechanically minded(me,lol) to follow, and gives the confidence to have a go and save cash
Just did mine last weekend - Charlie nailed it. If you remove that brace you can get to all but the driver side uppermost nut. For that one just put a deep 14mm socket with a 4” extension on the nut, then go from the top. No corrosion on mine so I didn’t even need a breaker bar, just the 1;2 drive ratchet.
Damn, I'm not looking forward to doing this. Thanks for the good video. So many of the other ones on here seem to skip steps or just get to the end without showing the struggle. Thanks again!
Hey, glad I could help. But yeah, they get pretty seized up lol. I wanted to show that it isn't as easy as some people think, It's always a little tough taking off the cats.
Jeez christ have someone who knows how to do it do it ...” so i couldn’t get to that one bolt so i’m going to go ahead and remove the engine “ ...so i removed another bolt and the engine feel out by itself “ whaaat lmao so i’m outside my house waiting for the tow truck driver who’s taking my z to the junkyard dbl lmao
Hey man - couple of questions for ya. I have a '10 ex35 and I'm hearing a nasty rattle at idle which I'm convinced are the cats. I don't feel like paying to replace them and have a feeling a straight pipe might be cheaper, but are those sensors going to cause the check engine light to be on? Where I live we have this "drive clean" program which won't let you pass if check engine is on.
There're these spacers called fowler's I believe. They space out the sensors from the direct exhaust flow causing them to read less of the emissions. "Off road use only" lol I'm not responsible for your local or state emissions and bypassing them
I have been trying to take the cats off my 350z for the longest. Just can't get those top bolts. I never tried extensions. Thanks for the vid buddy. Keep it up!
Great video, those top bolts are why I paid someone to install my new cats.This channel is going to blow, there are no truly dedicated channels for the 350Z besides mods and assorted BS.Keep up the work!
I hope so bro! I honestly didn't expect to even get to where I am now lol. Thanks for the support tho bro, getting comments like these are what make me want to do more!
got any tips about if the bolt rust welds on there? been having trouble getting the stock 2003 y pipe off , the bolts anyways. and is the best this to get an impact rather then try and use a rachet?
I have a question, I own a 350z 06 and I just want to know if i have a bad catalytic converter or it’s just the 02 sensor that I need to replace. But I hear like a rattle at the bottom right of the car like when it idles. My check engine light did came on and it mentioned a code P0420 and threshold bank 1. I just don’t want to go in a shop and get ripped off for a simple fix. Thanks
This was over 4 years ago my guy, sometimes it's necessary to go from the top, sometimes it's not. How much that's removed also depends on how much rust
What would you recommend for converters? I'm in California now and they just made a law against exhausts over 95dB. I have stock headers, converters, then an ebay exhaust setup past that. Can't even tell you what the brand is, HKS? It sounds like shit. I figure I want to replace everything past the headers (or should I use the eBay headers that came with the ebay kit that I never installed and install that)? Sorry this is difficult to word. I figure stock headers and a new ?converter? but I want performance while trying to stay under the legal limit + something new after all that. The reason I want to keep the headers and converters i because I'm sitting at 87dB at the limited RPM range of 2500RPMs. That is pretty close to 95 as it is and I was told keeping the headers and converters stock will allow me any exhaust past that to be used. Since I'm already down there, I'd like to replace the converters but just wondering if there is anything that is slightly better than stock. And if so, should I mix the brand with something else?
I've heard that the Motordyne ART pipes have the best sound without the rasp of typical test pipes. But neither test pipes, or the ART pipes are street legal in Cali. I wanna go with the ART pipes as soon as I start the install of the Motordyne tdx2 exhaust system I'm putting on my Z. But berk hi flow cats are supposedly nice sounding while also offering some type of catalyst for the exhaust, but, also restricting the exhaust flow, even though it's not as much as stock.
Awesome post - I’m going to.be installing Berk RTP’s and an Invidia Gemini system in the next couple weeks and your tips are definitely going to help. Thanks!

Thank you so much for the video...I work on my G35 sedan and 350z myself and your videos are a big reason I have the courage to.
Great technique and even though I have a G37, the principle idea applies. Thanks!
Yeah, it's pretty much the same for the G37, besides that you have twin intakes. So, a little more to take apart

Hello, what do you do with O2 sensors? If you don't want cats back on?
Can i just cut them off and replace them with a straight pipe?!
that looks like a pain in the ass job so ill let the muffler shop do it

How would my z run if i remove my cats and just run straight pipe?
It wouldn't sound that good, but it would run about the same as with cats
Do the new cats have to have those braces like the original ones?
Love that 10mm socket to remove the plastic clip.

I have an 06 and there’s some smoke that comes out of under the car believe it’s the cat?
If I have a nut splitter could I use this on the HR cats? To make the rust a problem of the past
got any tips about if the bolt rust welds on there? been having trouble getting the stock 2003 y pipe off , the bolts anyways. and is the best this to get an impact rather then try and use a rachet?
The socket you use to remove the cats was it a 6 point
Yes, 12 point sockets like to strip the hardware. Especially when excessively rusted
@@fullthrottleperformance ok thanks 👍
is there one bolt welded onto the header?
Y’all do the same rules apply for 06 g coupe
Yes it's the same
got 350z 07 cats for sell lol i cant find ones with for a decent price ! if anyone knows where pls let me know !
A lot of people won't sell them because if you get caught selling them it's a fat fine. Good luck tho!
Are you selling stock cats for an 07?
Full Throttle why is that so? Like why do they fine you for it.... it’s pretty annoying I had to get downpipes to replace my cats lol it’s alright ig
Juan Posada people stealin em
How many catalytic converters on a g35/g37 ? 2 on each side or 1 on each side ?
One
Can you pull a DE engine and trans out with the Cats on !
Yes, we do it every time. Car has to be lifted higher than the cats though, or manifolds anyways
I did it on the garage of my floor? Now thats a confusing way to say your garage floor is covered with tools on the ground.
Would running a high flow cat with a stock exhaust be stupid? Lol sorry new to this
No, I've seen HFC's with stock before. It's up to your personal opinion, fuck what other ppl think about your exhaust lol
Anyone have a link to cat removed sound clip video only?? Thanks
Here's one with the MD TDX2 with Megan Catless down pipes

I have a question at 7:58 when both cats are removed the plates above them are they both removable or do you have to cut them off?
You don't need to remove them
@@fullthrottleperformance Oh my question is can they be remove by bolt or are they welded on the chassis as my new test pipe rubbing against it.
@@braesbal9236 if you're talking about the underside chassis heat shields, they are removable with 10mm
@@fullthrottleperformance You happen to know how many bolts need to take off to remove and if its removable without taking test pipe off?
@@fullthrottleperformance My issue is my y pipe is hitting the chassis and heat shields hitting test pipe cause vibration in the steering wheel...

22mm

You did the most my guy ! I didn’t have to remove anything but the transmission bracket holding the cats and removed the cats and the y-pipe
This was over 4 years ago my guy, sometimes it's necessary to go from the top, sometimes it's not. How much that's removed also depends on how much rust
so i replaced my stock cats and my new ones dont have a transmission brace what can substitute for that or what do i do in that case
It's not critical, I haven't ran one in years
What tools would I need to do this?
Breaker Bar, 14MM Deep Sockets, 12mm socket, multiple extensions, etc. Most is covered in the video
22mm for the o2, a mid-high torque impact would help too
Me cats were hell even when i had the transmisssion out

nobodies heard of a wrench?
Try getting to that top nut and breaking it loose with a wrench, doesn't work so well
Can a DE cat be used on a HR car?
No, exhaust manifolds are different
So stupid mechanic engineering! Thank god for American cars..
