Ummmm......Thanks for the news!!!

me and a buddy did the install one mine and the instructions say that, unless i am reading wrong, that there should be 3 O2 sensors. im not sure if the 07's are different but i could only find 2. anyone that has the headers for the sedan, can you help out with this? where does the bung plug need to be? thanks guys.

[el_blacky06]

well as far as i could see myself theres only 1 sensor dat could go to the adapter but since i have a custom made exhaust without cat it wazant necessary for me to use it. i believe the kit comes with a bolt to cover one of the holes on the adapter try to use it and see if it helps. and for people with custom downpipes use a flexible because the backpressure would most likely damage the piping and most likely snap off

are you planning on buying the headers? if you do let me know how the install goes. i think we have the problem figured out. thanks for your help.

MY HEADERS HAVE BEEN INSTALLED B 4 I POSTED THE BULLETIN AND LIKE ALWAYZ I RAN INTO A FEW PROBLEMS BUT I GOT IT WORKED OUT

el_blacky06 : Did you get SES Light when you removed the cat? Did you reallocate the O2 senser?

Cuz I'm going to do custom exhaust this week direct from header till the end and I'm planning to remove the cat, but I don't want to get SES light.?

what kind of problems did you run into?

[el_blacky06]

i tried putting a downpipe without the sensor and dat caused the ses light to turn on. with dat happening u gotta make a hole custom made by a welder and once the sensoris on then it should go off

what kind of problems did you run into?

just the sensor problem and another thing is the headers it turns out after u tighen the bolls theres a small gap between the headers and the downpipe so it causes a ratling noise when u step on the gas so it needs a gasket to cover the gap

Thanks man for the information I will try to get the custom exhuast asap :>:>:>

Another question Did feel so much improvement in the performance when you made the custom exhaust without the cat?

what did you about the sensor issue? did you have to many bung holes?

[el_blacky06]

the sensor i placed it at the same spot where it belongs in the cat. on the downpipe make a custom hole for mine it waz made by a welder itz very easy to make

[el_blacky06]

itz not much improvement maybe at the most 5hp for the downpipe plus another 8 to 10hp for the exhaust. the good thing is itz a bit more gain and u could backfire which is cool for me
