Default Cobb downpipe installation (some pics)

The package from Rally Subaru finally made it to Calgary ( had to pick it up at the depot because Jeremy wrote Ave instead of Street on the label). Took a few hours but got it done. The alignment of the downpipe is spot on.

Wrapped the whole thing in thermal wrap. Don't know how the bottom part will stand up to road debris but since I had a 50' roll...

The silicon sealant smokes pretty good and smells like...toast?

Now I just have to wait for the effect of AP Stage 2 to kick in

looks good - thats the catted one correct?

You still with the stock catback? If so, how did the downpipe mate with it?

Should have stopped at the bend with the wrap. Paul (ex- Rally mechanic) said he has seen a few done like that and it doesnt last long as the bottom gets so chewed up it just starts to peel all the way up the downpipe. He said to make sure you stop at the bend.

Looks good and hope it stands up for ya.

I have a silly question : What is the purpose of the heat wrap on the down pipe? I can see why the up pipe would benifit from heat wrap.

to keep the heat in plus to try and keep under hood temps down to......dont know if the benifit is huge but its a cheap easy thing to do before the install....so any benefit is easy to acheive.

Yes, it is the catted version...wanted to keep at least one cat. I have the stock cat-back. It mated up perfectly without any fuss, using the stock donut gasket.

Probably should have but I had that big roll of thermal wrap, I just couldn't help myself once I started Maybe I could add a couple of sections of metal heatshield and attach it with some hose clamps. Would galvanized sheet metal hold up?

If nothing else, I could add a couple of hose clamps to help keep it from unraveling.

Yeah, it was a now-or-never type situation. It should provide some sound insulation as well.

I'll trim the stock heatshield and put that back as well to keep the heat out of the engine bay.

Putting some extra clamps on it would probably really help if it starts to come apart. I dont know if I would try to rig the heat sheilds back on it again though. They will probably just rattle and annoy the hell outta ya.

If you dont want to cut the turbo heat sheild, cobb makes a really nice one that fits over the larger downpipes. Im putting mine on today

I cut the stock heat shield and put it back on. Had to cut a fair chunk off it though. Cutting instructions were in the downpipe installation guide.
