I am looking at getting the Cobb turboback (w/cat conv.) and Helix uppipe for MY05 WRX sedan. Is this really difficult to install? I have never done any type of exhaust install before, basically the only things I have ever installed are my rear sway bar & endlinks, Kart boy short shifter & bushing, car audio, front & rear strut bar. If I wanted to install this myself are there any major tools that I would need (ie. torque rench, lift, welder.....). Does anybody know roughly how much it would cost to get this installed by a mechanic in the Seattle area? I really appreciate any information that you can provide.

Also, do you think that with this setup I will have problems with passing Washington state emissions tests?

 

You can do them yourself. The uppipe is a pain in the **** because you have to jack up the engine to get the stock one out. The turboback isn't too bad just plan to take a while on your first time. But if you want is professionally done go see Garret at worldoneperformance in West Seattle. He is a stand up guy and his crew does good work.

As far as emission, I dunno you wont have to worry about it for like 5 years. Also, now-a-days they hood up to your ODBII sensor in your dash so if Im not mistaken if you do not have a CEL than you are good to go. So save the money and don't get the cat, and get an accessport. Just my opinion.

Laters,

Yeah the T.B.E. is pretty easy , there is always a chance of having frozen/galled bolts and nuts though - even on low hour rigs. I would start hitting Fast. with penetrant oil before you pull off. And see if your 02 sensor is in a different place (hopefully closer in). Also WD40 your hangers before removal.

If your going to pay someone to do your uppipe you could probably throw $50 or so, and have them do your exhaust while they're at it.

 

UP install is a bit expensive if you have a shop do it.

Best to just "nut up" and do it yourself.

Use WD 40, 6 point sockets, new gaskets and lots of man juice like Dan.
