Top Mod/upgrade for compliance with CPO
Fully aware of the difference in opinions regarding what will and what won't void the warranty, looking for opinions from the community.
I have the ability but not the time to remove stuff prior to going to the Dealer which I will likely do for routine service/maintenance as much as I like to do it myself. Does replacing the exhaust make sense? |

If you don't have time to remove parts before taking it it for service just get a flash tune. Only take a Minuit to remove.

A BMW performance exhaust would not void your CPO but it also wouldn't do anything for performance. If you want something that will add power and also be easily removed, I'd recommend a cobb tune, intake and charge pipe. The tune and intake would take 15 minutes to remove and you could probably leave the charge pipe installed.

Very much appreciate the input, thanks.
Kinda surprises me that as old as I am and as many cars as I have had that I practically want to park this one in my frigging bedroom. Three months in and this is a serious love affair. This car rocks. |

The path that I took while I was under the original warranty was a charge pipe, drop in k&N filter (which probably didn't do much) and a Cobb AP which I tuned for a 40% blend of e85 / 93 octane. That alone probably got me well over 400 ft/lbs of torque to the rear wheels. If you have a little extra cash I'd suggest a low pressure fuel pump upgrade to handle more ethanol. High concentrations make IAT less meaningful so you can skip the intercooler.

Just be aware that if they really dig (say engine failure) they can see that an AP was installed. It shows in your maximum boost level that is stored in the ECU.

JB4 or Cobb AP are your best options. If you are okay with opening the hood, unhooking the sensors and hooking up stuff to the sensors, you will be fine with JB4. If you just want to plug into the OBDII port to flash/remove the flash then get Cobb AP.

I am finding conflicting info on this now. When I got my tune over a year ago most of the info said there was a counter that started at like 99 and went down. Now it looks like Cobb has found a way around the counter. I can't say one way or the other now.

There is a flash counter and they can tell if it was flashed. It does not mean an automatic revocation of your warranty, but will allow them to dig deeper if they want.
That said I never hear of instances of them looking at the counter unless it is major warranty work; IE, blown engine. |

I've gone into the dealer FBO minus my JB4 and all went well. Of course I consulted my SA prior.

Really appreciate the input/advice. Cobb AP3 allows to easily flash back to stock which is nice And it's like a hand held modifier and the JB4 is a fire and forget missile. Decisions, decisions. Charge pipe and intake appear to be a no brainer and then there is the Downpipe to consider.
I have read a bit about some mods throwing codes, anyone know which of the two are more likely to do this? |
