Just got my midmuffler removed and replaced with a pipe .. why am I getting a CEL ? Have any of you guys with the midmuffler removed experienced this too ? I hate driving with the CEL on .. bothers me :[

 

yaaay you got your car back....

did you get a code read?

 

no i didn't .. but im sure it'll be something about my exhaust ): . i feel like taping my dashboard so i dont see that freakin light

 

i had a code scanner... gave it back... get it checked and tell us what it is..

 

there's nothing electronic in the midmuffler nor would i think an o2 sensor would be in there. reason i say get code read because something could have coincidentally popped up during the install? i'm just taking shot in dark.

 

I would look at the )2 sensors, the exhaust shop may have let it hang by the wire or yanked on the pipe hard enough to damage it. Reset it and see if it comes back on.

 

yeah i just got my exhaust done and the second i leave i got a cel. so when i got home i jacked her up and the pins were pulled out a little from the o2connector. i just pushed them back in reset the ecu and CEL never came back.

 

exactly what happened. i just went to get it read. PO141. they didn't use a stand when they removed the mid muffler .. man sigh .. they only used the stand right after it was left hanging .. lol

 

i told the guy to reset it and he did .. but right when he turned the car on again .. it went back on instantly ..

 

tell them to replace your o2 sensor for free with OEM.. none of that cut off old one and splice/solder in new one... crap job... i hope you paid like.. $5....

 

It not the sensor. Tell them to check for Leak where they weld it. Same thing happen to me just a little needle size leak.

 

A leak in the exhaust where the resonator or mid muffler are would NOT cause it. I have run NO exhaust from the cat back and it never triggered it, nor should it. They damaged his O2 sensor.

 

like kris said, if it was a leak it wouldn't trigger a CEL, it would just be annoyingly loud.

 

Its the pins pulled out a little on the connector of the o2 sensor for sure.

 

I went yesterday to get it checked.. all 4 pins were disconnected when he checked it.. the guy doesn't know which color pin goes into which hole ... any of you guys know which pin goes in which hole ?

 

went to the muffler shop yesterday and had them fix my o2 sensor up. like sohcisme said, just push the pins back into the connector. all 4 of mines got pulled out, so it took them awhile to figure out which pin goes into which hole .. but in the end, no more CEL !

 

Just saw this. Glad they got it figured out. (if not i could have given the pin/color

 

Im thinking of getting mines removed too. Is it loud and how does it sound? i dont trust youtube sounds =]

 

oh and i was just wondering is it only for sound? and do you recommend it. i dont want anything loud cause cops in my city are very dalsfkjas about it

 

midmuffler is only for sound . tsudo sp's were too damn quiet .. so i had my midmuffler removed .. it sounds nice and deep now .. its not really that loud tbh . its bearable . i'll post a vid up soon .

but if you're stock and just plan on doing the midmuffler removal .. it won't sound THAT loud after .. theres videos on youtube you can watch but like you said .. you don't trust youtube sounds .. guess you gotta hear it in person

 

is there any downside on doing this mod??

 

yeah, if you don't like being awesome.

 

there is no downside .. midmuffler delete is like removing the resonator .. it's just for sound .. with the midmuffler on ... it basically resonates the loud engine noise . you don't lose power or mpg .

That is no mid muffler, AERO AR25 resonator, and Magnaflow "RACE" mufflers, which i believe are just large resonators, after 12 seconds, that is basically what the car sounds like, check out my other video for mid muffler delete, aero resonator, and stock mufflers.

 

The downside is you might get a CEL if you aren't careful....

 

^ negative. you won't get a CEL at all unless the muffler shop (like mines) doesn't use a stand when cutting off the midmuffler. basically causes the pins to get pulled out when the rest of the exhaust falls/hangs. make sure you tell them to use a stand. it will save you time from putting back the pins (in my case, all 4 were pulled out when the exhaust fell/hanged). putting back the pins would also require to use a lift, unless you have a racing jack & good lighting underneath.

and if you do get a CEL for anything other than the pins getting pushed out.. it's most likely a leak in the weld. just tell them to reweld it and clear the code.. should be good to go after. but otherwise, this is just a cheap mod for sound

 

You just said what I said in different words...

 

i was just being more specific so people reading thru this thread would know what to do in that situation

 

lol luckily i am awesome

and thx guys for all the info
