got everything done in my garage after work. sounds great and defenately feel the torque gain thank you guys!!

 

oh, guys another question.. i installed megan test pipes yesterday and reused the stock o2 sensors on them. i just took another test drive and the check engine sign came on. i'm pretty sure its going to be PO420 or might be something else. i don't have the codereader or scanners to check em. the problem is, my state inspection expires on FEB 2011, i have about 10days to fix the CEL. i saw videos on youtube using non-fouler, drilling that thing with 1/2 drill bit... does that also work on 2004 g35 coupe 6mt? there are 2 o2 sensors on testpipes and another 2 o2 sensors on the headers. am i supposed to use 4 non-foulers to make the CEL go a way? i need HELP asap PLEASE!!! Q_Q

 

I believe its just the 2 on the actual TP's. I had a CEL(for throttle body not test pipes lol) but i went to BIG-O-TIRES and they cleared it for me for free.

Emission guys didnt even know.

 

u can buy 90 degree non foulers should work and yes its only the 2 o2 sensors in the test pipes dont worry about the header ones..or just get an osiris uprev tune..will clear all codes..heres the link for the o2 fix

before i installed my test pipes i got my inspection done which was a month early but then i had plenty of time to get my uprev tune...reset the ecu after installing
