My friend told me that I will need a new o2 sensor and ECU or an ECU performance chip now that I put the back pipe off of an SRT4 on my car. also that I now run the risk of scorching my rings since I'm running straight pipes

is this true?

 

please, i need help

 

No you dont need any of those . Ive had my srt exhaust on and no problems at all. If your worried put a glasspack on to be safe.

 

you sure? he said my performance and gas milage will suffer if I dont get them... and does the new exhaust kill my gas milage?

 

no...... Chips dont work on neons. I have an srt-4 exhaust and no problems. When you add mods u sometimes get better gas milage since u let your engine breath easier and leting exhaust out faster

 

well, he told me since i opened up the exhaust I eliminated backpresure and now it will draw more fuel and air into the system thus killing my gas milage

 

or something like that

 

no need too worry your friend is kinda right but also kinda wrong. your o2 senser will keep the afr where they should be

 

but will it hurt my engine any? and what about gas milage?

 

the gas milage has been heated subject between me and my friend. But either way you will hardly notice the difference but you might if you get the heavy food sickness that comes with modding your car. But in theory all air flow mods will hurt your gas miliage since more air means more feul needs too be injected. butwhen I took out my cat I saw increase ingas milage .
