Ok. this is an easy question and i probably should have searched. please dont flame!!

bought my dad a invidia bellmouth downpipe and hks hipower catback for xmas.

gonna be installing christmas eve and i wanted to know if there were any tips/pointers to this before i start and find myself stuck between a rock and a hard place.

looking at it, it looks easy but i wanted to check.

its an MY02 wrx. all stock at this point.

 

Nothing too complicated. Just removing the stock heatshield from the old downpipe to get to the bolts and everything else is just basic bolt on. Might wanna pick up a can of WD40 to get those bolts loose and if the parts are used, new gaskets for it. Besides that you should be good.

P.S. You will need a mechanical fix

Something that looks like this for the 02:

Good Luck

 

Haha. Well yes the parts are used and it has that fix. its different from that, it has like two fittings that just make the o2 sensor rise up outta the pipe. i didnt know what it was at first. i havent been in the subaru coomunity for awhile.

 

spray the bolts with wd40

 

+ 1 also spray it on the exhaust hangers.

 

Cool! Thanks for the tips guys. I have PB Blaster (a rust penetrant and lubricator) at work and special exhaust hanger tools that should do the trick well.

second question...

estimated time to do this? it will be on a lift thankfully.

 

2 hours maybe, give or take depending on the bolts being hard to take off.

 

hour if you're fast and know your way around.

 

I'd say 2 hours is plenty. but you should take your time. and do it right the first time.
make sure you check the clearance of the piping when you are done.
