just get you a 3" turbo back set up .. i have the ZZP catless DP and ZZP 3'' to magnaflor muffler at rear with 4" tip .. sounds good .. does drone on highway though

 

im saving up for the catless DP and im looking around for a tip now, i hate the one that is on it, it does a little but just turn up the radio, ill probably end up getting the DP when i dont have to commute so far on the highway just incase it does drone

 

The drone isn't that bad... if the radio is on. really its not that bad. When you get the cat-less DP be sure to quickly re-tune or buy a code reaader/clearer. the O2 will read way too much, another clue the motor overcompensates and you will notice a slight 5-10 degrees rise in engine temp for that ignition cycle, on your next cycle you will have a check-engine with P2096 post-catlyast something or another showing one to two times on a scanner. depending on how you drive you could see a code everyday or none for a few weeks.

Just to let you know what your getting into before putting on a DP, even the ones that come with a de-fouler welded in will still throw a code once in a while. FYI

 

Changing downpipes will not affect your coolant temperature.

 

sorry not your coolant, was tired when posting. I meant the outgoing gas that the O2 senses, its temps are slightly higher.

 

The oxygen sensor doesn't read temperature either.

 

No panel, it doesn't but I do, and when I don't have something I want to monitor, I go out and get it. Like a hand-held temp reader. Jesus, does the car have to tell everything? Btw, when it throws P2096, it affect/effects the entire paramaters of the engine. An don't say it doesn't look at a data-log it throws the code, retards the timing, and leans the fuel... thus causing some temp increase in the entire engine. coolant and exhaust both go-up.

 

Calm down friend-o

The rear O2 sensor is only there to monitor how well the catalytic converter is working. All of the Lambda readings come from the wideband sensor in the O2 housing.
