I know alot of people have changed their downpipes. Anyone care to tell me what size the nuts/bolts are? If you don't mind, how many extensions did you use? I cant find my deep wells or extensions so I'm gonna have to buy new ones, that's the reason for such a lazy sounding question.

 

i believe 17mm was it. and I think I used 2 12inch extensions

 

sweet, thanks man

 

it's funny you asked because i had to change over my catless downpipe to my factory one today for an inspection. And then after the inspection i came home and put the catles back on. I can do it in like 5 minutes flat now lol.

 

I think I'm like that with the intake now, I swear I've had that damn thing off and on like 6 times.

 

lol i unfortunetly have the dejon intake (I sold my stock intake stupid stupid stupid)

 

That sucks, I use to have the Dejon as well, but sold it a few months ago once I learned how it affected fuel trims.

 

You used 2 12" extensions to remove the downpipe do you really need 24" just to reach the bolts by the turbo?

 

man i want a DP..... i cant seem to find anyone selling one for the T/C... or there really expensive.. ive only seen HAHN's DP

 

i got my catted DP from CIA for 315 shipped...

and it woulda been 50 dollars cheaper if i got the catless...

 

pretty sure it was a 15mm that is needed for the DP

 

That's what I remember as well. Buy a 6 point set, better bite.

I think I used around 20" of extension. Drop the turbo end first, then you can access the rear joint top nut better.

 

15mm it is. A long extension helps, but if you just undo where it couples to the rear section first, you can bend it down slightly and it makes some room for you Should take no more then an hr!

 

ok i just checked again and mine is 17mm. lol maybe some peoples are different lol i dunno

 

yah im thinkin of getting a Catess cause the ca isnt loud at all... i dont want obnoxiously loud but im sure it wont be like that if i get catless hell might even gain a few horses

 

ZZP Catless was ~$250 when I bought it. I like it a lot

 

heres the thing though i got the Hahn catback... is it gonna bolt up to it?? cause i got the connector to the stock DP... hmm i might as well just go do some research

 

If it bolted up to the stock DP it will bolt up to the ZZP DP.

 

found a vid of the clear image automotive DP ont he hahn catback on the turbo cobalt... lovely sound...

 

jeezes changing DP's is a pain in the ass. had to take the catback hangers off to let the catback hang so i could get to the top bolt on that 3rd bolt flange. and the extensions for the turbo suck. Only had enough extensions for a 3/8" ratchet, but went out and bought a 1/2" -3/8" adapter so i have more leverage getting those nuts loose. changed 2x so far, after my inspection i gtotta do it again lol.

 

Just pull down on the exhaust a bit and you can get to that top bolt pretty easy. I used a deep socket with no extension and got it off without too much effort or aggrivation.

 

i got a 300 pc craftman tool kit + some extras i acquired, but one thing i dont have alot of is deep sockets, what a pain

 

Ahh!! Thats the difference!

 

I just bought a metric set of deepwells at harbor freight for like $10- they're tools are so damn cheap! So whether mine are 15mm or 17mm I'll be set. Thanks for the info everyone.

 

Not a prob, good luck
