I've got a 2007 TC with the Turbonetics kit and I've had her on the dyno with a great A/F and power numbers. She's around 262 HP and 263 FT/LBS. That is running the 7.5-7.8 PSI the kit comes set up for. I want to get a AEM UEGO wide band but was interested in mounting options. I still have the stock S-Pipe and I have a Magnaflow catback. I am running the AEM F/IC for the tuning. I was wondering if I could replace my 2nd O2 sensor with the wideband and let the stock ECU read off of the wideband sensor and tap the wideband signal to my guage at the same time? If not, I can get the bung welded to the S-Pipe but I was trying to eliminate welding exhaust components because I live in Florida...land of rust. Last question, is it worth it to purchase a new S-Pipe (as far as power goes) or is the stocker fine? I don't plan on getting crazy with the boost. 9 lbs at the most. If so, which brand do you recommend?

 

there is no way to get the stock ECU to read a wideband instead of the second o2 since the stock sensor is a heated oxygen sensor. if you unplug it you are going to get a CEL for catalyst efficiency (which you are probably getting anyway)

get a shop to weld a second bung for the wideband

 

You could remove that remove that sensor and replace it with the wideband sensor but its just a better idea to have another bung welded next to the stock sensor. IF your worried about rust, spray some high temp paint on the weld

A new S-pipe will help the exhaust flow more freely, but if you are not crazy about power, just leave your stock one on

 

Sounds like I'll just weld in the new bung. No big deal, just curious if I could save drilling another hole. Anyone have any idea what brand makes a nicely fit S-Pipe. I hate aftermarket crap that doesn't line up... I'll gladly pay extra for a nice piece than save a buck here and pay for it later.

 

i have a megan spipe no turbo it it fit perfect...

 

iv got the megan s-pipe aswell, iv got no complaints.

 

crush give me ur s pipe

 

ummmm....no...lol...i dont have the stock s-pipe to put on, i gave that away to java (brandon)

 

ive got a stock s pipe in my spare bed room with ur name on it ur going 3 inch full exhaust when u go turbo again anyways purdyyyyyyy pleasseeee

 

the idea of going 3" exhoust got scrap'd...idk what im going to end up doing but id like to keep what i have just incase i do go boost again...less i gata buy later.
