Broken Cat...decisions decisions

this sucks man, hopefully the new exhaust will be more forgiving on the rest of the system and that fixes the problem.

When aftermarket stuff starts to get to me by becoming a pain in the ass, I revert things back to OEM, you might of noticed my car looking more stock lately ;). … but this is all part of the modding process and is pretty much expected. mo mods mo problems.

People who mod their cars rarely keep them for 5 or 10 years

Speaks to the personality that they like to change stuff up but it is also the case that so many people who do all of their mods decide to sell their cars shortly thereafter

drob and I are committed to the B8. B9 doesn’t do it for me. I have to go drive a base $89.9k 991.2.

Got the O2 off and the broken pipe out, now need to get the flange bolts off. I can fit a 3/8 ratchet in there but hard to get enough torque on it. The other option is a wobble and bunch of extensions. Will spend some more time on it. Ugg.

yeah, some people can’t stop modding until they ruin the car, then they dump it, making it someone else’s problem.

I wrote a diatribe about this on AZ called technical debt and modding. Everyone who makes a 450 HP S4 for $800 is guilty of this. Proper modding costs $25k.

It only costs a few grand to get started but to make the car reliable for 100k miles you have to put the cash in. Those people have the option of keeping the car.

Nah I think the b8 is just fine running stage2 tunes and pulleys and an intake. You could run thay for 200 000 miles and any problems you ha e would have shown up anyway.

The Germans over engineer the hell out of these cars. The one area on the b8 that was plagues with issues on modified cars was the dsg . Two things though

  1. Stock people were having tons of dsg problems too
  2. Audi ditched that transmission after a short 6 year run

Sorry about not updating this thread, been busy with work, sick new puppy and football weekends.

To update this thread, I met up with CV, and I’m gonna flat out say it, nicest guy I’ve met in a long time. He helped me repair the test pipes along with my broken cat (completely selfless on this front), went out of his way to get them from/to me (we live on opposite sides of town), and is helping make sure I get the car back together. Just can’t say enough nice things about the guy. Definitely makes me appreciate the people here who are willing to go the extra mile to help each other out. I’m definitely indebted to the community and will do my best to help the next guy. Although not sure I can ever help to this extent!

Here’s the weld porn

I have the milltek exhaust sitting in boxes, and 5 of the 6 bolts installed on the test pipes flange. I’m gonna take another hack at it tonight, and hopefully have the car running before some people come into town this weekend for the big UM/MSU game. The passenger side inside bolt is a #@!#@, have to get it on blindly using my bore scope to guide the socket. Requires a lot of patience that I don’t really have ;D

I can see how the milltek is going to be a bitch to get on, like 15 different pieces. If anyone has any words of wisdom, I’d appreciate it. Other than get the system all installed with bolts loosely tightened and then tighten bolts front to back to ensure proper alignment.

Looking forward to driving my car again and getting out of a tiguan I’m borrowing from family 8) Hard to take on-ramps at only .2 G :’(

yo wow that’s amazing.
those are nice tigs too. excellent job for sure. the guy was very careful about it all.

i’m laughing at your exhaust install. the blind bolt threading and use of a bore scope HAHAHA. i do not envy you one bit.
sorry, no advice. maybe have some beer?

:smiley: Thanks! Yea, the exhaust install seems like a cake walk compared to getting these test pipes on/off. The flange bolts, O2 sensor, ugh…

But yea, my solution to these kind of problems is to only wrench for a little while…once you get frustrated, I tend to spend hours and hours on something that ends up taking 10 minutes the next day. So a clear head and plenty of garage space are the ingredients to success 8) Things get worse though when you need the car back for daily transportation. I’m lucky that it’s ok to have the car on jack stands for a couple weeks. But this has definitely made me second guess wrenching on a daily driver, the stress factor is 100x worse when you need the car for normal day to day shit.

looks like your pipes took a trip towards Port Huron. Nice one.

Leave it to the axle man to come and save the day!

CV for the win

Got the last flange nut on there, was quite the setup with the bore scope zip tied to provide eyes on the inside bolt. It was difficult to make sure the nuts had adequate torque, but at this point, I think they are on there pretty tight. Going to work tonight on getting the new exhaust on.

Took off the neuspeed and I’m pretty sure the root cause of my issues is likely seized flex couplers on the neuspeed downpipes. The amount of movement in the milltek downpipes compared to the neuspeed is much greater. The Neuspeed exhaust sounded great, but I think it droned around 2k RPM, and the vibration was never attenuated at all by the flex coupler. So basically, the entire back section load was being transfered to the cat/test pipe flange when there was vibration. At least that’s my theory. Going to see about Neuspeed warrantying the down pipes, so the next owner at least doesn’t have to immediately deal with problems.

In terms of the milltek install, I made the mistake of tightening the downipes and it was IMPOSSIBLE to get even the first section to slip onto the downpipes. This thing is a real bitch to install on jackstands, the first section needs to be rotated in pretty much all 3 axis to properly mate with the downpipes. Already contacting local shops about installing it for me :-\ …

pay CV $200 for the use of his lift

CV is the man its great he was able to help you as he has helped so many of us we all are here to help and I think the troll types just get mad that they get shuned by all of us because they are not here for the community but just themselves.

As for the catback install. You found out you cant install the dps all the way and then try to put on the catback it will be a mess.

I was going to say something but in your post about installing the exhaust you said this

That would have been my advice so I didnt post anything

Thanks Justin, ended up getting it on this afternoon. Trick was to take off one of the downpipes and then slip both sides on, then install the downpipes. The tips are mildly close to the valence, so I’ll need to readjust them.

And wow…this exhaust is REALLY quiet. Almost depressingly so lol. Probably should have gone with non res. My xpipe modded stock exhaust and nuespeed were a lot louder. I guess from drone mostly lol but I loved downshifts, now can’t hear much.

There was some burning smell and smoke from the engine bay. Wondering if it’s just residue burning off. Could see faint smoke when I pulled to a stop light.

Will keep this thread updated with how it goes.

Tips look nice with the diffuser. Surprised you find it quiet especially being catless, those resonators must do wonders. I could use a pair on my car lol

Good work. I like the tips. They look good. And yes with catless you would think it would be a little louder.

The smoke is normal. It comes from the oil on your hands and any spray stuff used. Also if the pipes were off a car for a while they can get residue as well. So its normal and should be heated off after a few days of driving
