i ordered the bbk catted x pipe and flowmaster cat back. it should be here friday. i was wondering if any1 had any tricks that i should know about when i install it. can i use wd-40 on the o2 sensors if they r stuck or should i just use some heat. any other tricks yall know would b nice :scratch:

 

The only O2 sensers I have ever replaced unscrewed, but I don't know what they will be like on a Toyota Matrix, but I wouldn't get WD40 on the sensor itself.

 

Typically O2 sensors have anti-seize compound on them. Be sure to put another coat on the threads when you re-install them.

WD is great on all the fasteners, let that soak for a while, especially if you live in a climate that has salted roads.

Air tools are gold, and so is a sawzall if you want to rip the old exhaust out asap

 

my bad i forget 2 change my profile. i no longer have the toyota. i have an 04 gt 5-spd in torch red. i bought it last saturday. 2marrow i will tackle the exhaust. i dont think it will give me any trouble but maybe the o2 sensors will. i didnt know if wd40 would ruin the sensors or not. if they give me any trouble i will try the torch and put some heat around them 1st.

 

If its an 04 I wouldnt see any problems at all getting them out...got any pics?

Congrats on the new car!

 

Just get a big open end wrench to take the o2 sensors out. Shouldnt be hard.

To get the nuts loose from the car, you may need to spray some pb blaster on them. Its a awesome penetrating spray and really helps out. With your car being an 04 though, shouldnt be tough.

 

i wouldnt go bbk x pipe whith chambered mufflers. i would have gotten an o/r h. or the dr gas x pipe.(the only x pipe that sounds good with chambered mufflers.)

 

well i got it finished. its got a deep tone from the outside. a little louder on the inside than i expected,but not bad. still got a little leak on the driver side where it meets the header. cant figure out why though. im gunna look at it 2day agian. i also put on the mach 1 grille and chin spoiler. wow what a difference. i never been a fan of the factory grille so when i put in the new 1 i loved it.
