328i AA headers and 2nd cat and res delete to magnaflow

The Maxican · 03-14-2015, 02:21 AM

So much hate towards magnaflow

I love the sound of my cheap universal magnaflow. Danny have Russ throw on a resonator. A buddy of mine put on an ar-25 on his exhaust (they're around $40) and he said it got rid of all the rasp

the first 1-3 seconds in that last video sound great, but then the rattle comes in without a resonator.

Sounds perfect to me, what an I6 should sound like and always used to until the advent of idiotic emissions control crap. Why rasp-n-rattle bother some is a mystery to me but I'm old so there's that...

I have the off-road tune that was paired for the headers. How did you find out it was running super rich other than looking at AFRs

dgritti · 03-14-2015, 01:57 PM

well one you can smell it from the moment you turn it on and also they guys at the shop said it was running rich and there obi tool told them that from what they said.

i have the aa off road tune and i yet to have it run right since i installed the headers 2 weeks ago its really starting to piss me off

i can actually hear my o2 sensor loosening its self cuz they can't get a tool in there to tighten it cuz its way to tight to get any wrenches in there

I've haven't had a problem with the way the car is running or preforming. People have noticed that black smoke does come out in high rpm wots. To me this seems normal. I would rather it run rich at high rpm rather than lean to save the engine.

When i first went to catless headers with a fresh offroad tune i had some weird idle stumbling when sitting in traffic. After a few thousand miles things sorted themselves out and no more strange idling.

thats whats happening now but i hear the 02 sensor loosening its self so i have to tighten that first then go form there

as for the smell its not a high rpms its high or low or idle its seriously bad. I'm cool with it as long as i can fix the problem with the o2 and the tune.

isn't that the car dumping gas for a cold start? You can turn it off with tuning

Did AA ship out their cold start tune modification and I missed it?

Cool! Let us know.

Tim07e90 · 03-14-2015, 05:53 PM

Slap those resonators back on. It helped with mine. It fixed most of my rasp.

dgritti · 03-14-2015, 06:39 PM

yeah I'm going to hit it with res and see but first i wanna fix the issue at hand with the o2 and the rpm issue then I'm gonna romp on it so i can have some fun i haven't been able to drive it hard yet

(((

631twentyeighteye · 03-14-2015, 06:43 PM

The RPM issue should work itself out as the DME adjusts itself over time. When the weird idle drops would happen i'd just raise the RPM to 1000 for a few seconds and it would usually cure it for a bit. Not really sure why it happened, but i know my DME was a bit confused so to speak since i had mixed up secondary o2's for a while until i corrected it.

I also put my stock resonator back on to take out some of the rasp when i went to catless headers, it smoothed out the note a lot especially down low.

dgritti · 03-14-2015, 08:11 PM

yeah down low sounds like s shitty honda but a res should take care of that.

They are liars if they are saying they can't tighten the O2 sensors. I did mine with the headers bolted on the car.

The 1000 RPM then to off-throttle dip occurs on stock tune as well, has to do something with the DME
