Autospeed connected to COBB Downpipe

Anyone have any problems connecting the autospeed exhaust to the cobb downpipe?

 

Did you use the factory spring bolts with the donut gasket or the autospeed gasket and bolts?

 

 

thanks in advance, Im gettting ready to install mine and was wondering if I would run into any problems with this setup.

A little late, as I'm guessing you did the install this weekend.

 

I have a cobb dp and autospeed cbe. They didn't mate up very well. I used a regular gasket and alot of copper silicone and that leaked. I went to a remflex gasket and a bunch of copper silicone and no leaks yet.

so did you drill out the cobb holes and use the autospeed bolts and gaskets?

i have a 05 LGT 5eat and I just bought the cobb catted down pipe and the autospeed catback exhaust.....please dont tell me that these two systems wont merge without a remflex gasket and a bunch of copper silicone........

Anybody else willing to chime in? Mine's going in Saturday and I want to try and head off any problems before we get there.

they tech guys at my subaru got the two systems linked great the only prob was the passenger muffler its a little offset nothing could be done.....its not noticable unless u are really anal and look them for a long time....other that that it sounds like a monster and im getting all eyes.....goodluck iuksob03

just be carefull if you upgrade your rsb. autospeed cbe has fitment issues with lowered cars, larger rsb etc. the exhaust note is awesome

I drilled the cobb bolt holes out and didnt use the bolts with springs anymore.

Put autospeed gasket and two stainless steel bolts and it worked great.

yeah we ended up having to run to get some smaller blots and doubling up on the gaskets. I've got an exhaust leak somewhere, but we think it's preturbo.

post some pics when you get a chance. Did you have to use the sway bar relocation brackets?

i actually just mock fitted mine up and then took it off.

I have an outback and I need to get the jdm bumper with cutouts so it will fit correctly.

We did use the swaybar relocation brackets. The brackets just slides directly in the same spot as the stock and pushes the bar forward just enough to avoid contact with the y-pipe. After putting the brackets on, the bar was very very close to resting on the bottom of the trunk. I've driven about 50 miles or so and haven't noticed any contact issues so far.

crappy cell phone pics

What sway bar you running? Is that stock or JDM or other

 

Also can you post some more pics with a little better camera.

 

Thanks

better pics, stock swaybar

Were you able to use the factory exhaust hangers OK?

Right now I've got a mix of stock and the kartboy longer hangers. I was shorted one on my order, so we didn't have the full complement at the time of the install. I would definitely get the kartboy hangers, they make life a LOT easier. Alignment was real goofy and quite a stretch when we tried the stock hangers. Right now I think I just have the longers hangers on the y-pipe and on the passenger side mufffler. I'll be switching the rest of the hangers out when we try to realign things soon.

You know I got the kartboys when i did a mockup on my outback.

 

The only problem is the karboy hangers really dont fit well. The holes are too large for the muffler hangers.

 

Someone posted under an autospeed thread somewhere that they got hangers from napa or some autoparts store that worked well. Ill probably go that route.

 

I really dont understand why this exhaust wasnt made to fit with the stock hangers

We didn't really notice any difference getting the hangers onto the hooks. They weren't as tight as the stock ones, but they were hardly loose by any means. I'll double check today to see if there's been any wear on them.

Ok, just checked the hangers again and there is a little more play than I remember. The holes are definitely a little too big for the hangers. I'll have to see how it fits with all of them in before I decide whether or not to go another route.

thats what I found on mine as well.

like i said there is a thread somewhere if you search on autospeed where someone gives the part numbers for hangers from the autoparts store

i have this cbe, and the kartboy hangers as well for a couple months now and haven't had any problems. they are a little looser than stock, but they have yet to just pop off or anything. i also retained the stock hanger at the y just because it had a little more give, and it let the exhaust hang a little lower because i was planning on getting cobb sways. by the way if you think that the stock bar was close, wait till you get a aftermarket bar!!!

Can you post some pics of your setup with the aftermarket sway? I just sold my perrin ones because I didn't want to deal with it if it was gonna clank.

Anyone consider getting a flex section welded into the mid pipe to allow it to mate up to the cobb dp better? Or would this just cause fitment issues elsewhere?

I think to have a flex section welded in, you would need to cut the pipe quite a bit. I think as long as you have some hangers with some mobility, the fitment should be fine. I'm contemplating taking the gaskets out and just putting one in. The issue for me was more for covering the whole diameter of the exhaust. The cobb flange is quite a bit smaller and thinner than the flange on the exhaust.
