I was doing some spirited driving on the backroads today and all of a sudden my car sounds like it has a campbells soup exhaust. Feels like I lost some power and the turbo spooled a lot louder. I went home and checked it out and my dad noticed that the catalytic converter wasn't connected to the turbo anymore. Heres some pictures I took real quick.

About how much should a meineike or some other muffler shop charge me to fix this? I'm not gonna even bother myself...

This happened to me a while back, it's actually pretty common. Any muffler shop is most likely going to tell you that it can't be welded back together because the flange and the cat are made out of two different metals; which is why it broke. From what I was told the two metals (Iron and steel I think) expand at two different rates and will separate from each other if not properly warmed up. You're better off buying a High Flow Cat (Techtonics Tuning sells one for about $300) or a test pipe than trying to fix yours. Whatever you do, don't buy another stock cat.

This happened to me awhile back as well. I got a pry bar from behind it, shoved it back into the flange then welded back together in the car. The weld has held fine for about 7k miles now.

This should be in the "You know you have a 1.8t when..." if it isn't already
Test pipe and get the old one fixed for backup.
Drove to work for three days like that and stunk like I tried to kill myself like Lane Myers when I got to work and home. (Was waiting for tp)

Test pipe would be nice, but I need the car ASAP and don't really want to spend $150, or the time to put it in, for a tp on a stock car.

I think I'm going to just pry it back in and have my friend tack weld it until I have time for a more permanent solution.

Typical gain is 200 to 400 rpm sooner spoolup and 40 ft/lb of wheel torque. HP gain is 10-15 on stock and K04 turbo and 30-40 on GT28RS or larger turbo.

40 ft/lb more torque at the wheels?!! Is that right? Thats insane. If thats correct I'd seriously consider it my next mod after the chip. Figure...

Stock: 150chp 155ctq
Chip: 204chp 235ctq
Chip + tp: 224chp 285ctq

This happened to me about 2 months ago.

I got a Techtonics High Flow Cat, was $299 as compared to the OEM replacement at $300

What kinds of gains did you see from it?

Not sure, never dyno's it. But I'd expect to see some gain, because its a lot less restrictive.

I *heard* the gains for a TP from a HFC are minimal. But I'd check.

That sucks dude, I got a test pipe before that could happen to me. Though my cat was almost impossible to take out.

I have a TT HFC too, the gains from a HFC are usually minimal but not from a TP. You can expect pretty significant gains from a TP from what I've heard.

Oh yeah, and be sure to only drive your car to get it fixed. If you're driving around, all of the heat coming out of your turbo is going to melt wires in your engine bay. Not to mention when you go to park it, especially at night when it's colder, a ton of cold air is going to get sucked into your hot turbo and into your engine and it can potentially warp valves which would not be any fun. Just a heads up.

Thanks for the replies guys.

Its at a local shop right now, they said they'll be able to pop it back in and tack weld it in place. Shouldn't cost more than $150, plus I'll get it back in a few hours.

Monro muffler told me that the cat had eroded away and I would need a new one, with around $450 worth of labor. "Welcome to the car world kid", fuck you asshole. The guy at Meineke was into Audis and VWs and told me he could install a new cat for me, but that the one in there was probably fine. He suggested just popping it back in and welding it, then he wished me luck. I like him a little better.
