I have this exact setup on my 2.5i and there are a few things you need to make sure you are ready for. Power gains are not going to be anything too noticeable, it will sound really nice though.
Make sure that you are ready for the o2 sensor issue. I bought the extender for the rear but for the front I did a quick relocation of the connector from the front to the rear of the engine. I will try to get some pics of this. You don't have to buy the extender but you will have to make the wires longer on your own.

dead on. there wont be much power gained but it will sound way better than stock. when you extend your o2 sensors make sure you use waterproof connectors. its smart to even heat shrink over those too

just wondering, do you NEED the o2 sensors? i know it will throw a check engine light but can it hurt the car in any way?

YES YOU NEED THEM! especially on the newer 2.5i's. You cant even use the o2 spacer method to get rid of the p0420 code on these cars

I ran my setup without o2 sensors for ~45k miles without any issues before finally breaking down and getting new ones (1 had been stripped when removing from stock) I would recommend just doing it the right way first.

well guys time to get this thread going.

got the exhaust yesterday...headers, hfc, and mid pipe. (already have a blitz axleback)

all cell pics, camera is broke



and the o2 sensor came in today!


Unfortunately, my main floor jack i always use broke! i have another one that a friend brought over but it wont even jack the car up high at all, its only good for changing a flat i suppose. so tomorrow, if i can get an exhaust shop to squeeze me in ill have the boxer rumble i also havent forgotten to take a dyno run with the accessport...will get pics of that tomorrow as well...
just another pic..

look at the last pic you posted, at the cat pipe in particular. see right after the flange up front there is a hole? thats for the front o2. the hole on the cat is for the rear o2. hope that helps

So i would have to make the wires longer? I was talking to the guy at boxer4racing and he said i should be good with just the o2 extender from casperelectronics. But he never mentioned that

The front should reach but you can just cut a little of the tape that bundles the wires together so you can spread it out and get a little wire to work with, the rear will be about 14" from reaching.

If the front still doesn't reach you can relocate the connectors from the front of the car to the rear. I will try to take some pics of the location of mine today for you.

both of em! ok so the front one didnt even reach none of the holes even with the 24" extender and the rear one is the same problem (wont reach). so the only thing i can do is basically have the wires spliced to clear the cel. i wouldve got some pics but i didnt even think of it at the time. but its so loud...turns heads everywhere! and i didnt even have to get the blitz axleback i had on there welded on. fit perfectly into the midpipe

I have the white otter box case for my droid, it gets filthy everyday from being greasy lol.

Extending those wires by cutting and splicing is actually pretty east. Use heat shrink over waterproof crimp connectors. That will seal them up good

yeah idk anything about wires so im taking it back to the exhaust shop monday and he said he would splice them up for me and i should be good to go. but i feel a difference in power believe it or not. the intake, full exhaust, and the accessport really gave it some more power...pretty noticeable if you ask me. not so much in the low rpm though. still need to get a video i just need someone to record it lol
