Warranty Issues with Exhaust Systems?
So I want to get the Akropovic Evolution exhaust system, but decided to talk to the guy who sold me my car first to see what the warranty implications were (he told me to get a tune and pulley and exhaust when I bought it-said they were the best ways to add power without voiding warranty)
His response was that high flow cats or an x pipe could void a lot of things beyond the exhaust "All the way to possibly the engine warranty being voided. I would only do a cat back exhaust system." I was wondering what y'all think about this. Can HFCs and an x pipe cause ANY problems with the car? Is this something I should worry about? I just don't want to risk voiding the whole warranty from an exhaust system. On that note, if I do end up getting an axle back system because of this issue, what are the best sounding systems to look at. I know the best in terms of complete systems but running OEM exhaust with just axle back aftermarket, what do y'all think? Thanks in advance for any help |

Highly unlikely that HFC's could do anything to negatively affect the motor. They are, however, illegal in most states as you're messing around with the emissions of the car. HFC's do make the car manufacturer's case a lot easier though in the event that they want to deny warranty coverage.
A tune and pulley have much more direct effects on the car, and I would never trust a salesman's word on those not voiding warranty. Frankly, I'm surprised he/she would say that. A tune would make it very easy for BMW to deny warranty coverage if they wanted to. Not so much a pulley, but if your power steering goes bad, forget about it. |

What mechanical problems could arise from using HFCs though? I mean, could they directly cause any problems with the engine? |

If you get a full exhaust system, your CEL will turn on and you car will run like shit unless you get a tune or get the Akrapovic "Delete-R". I would recommend you the Akrapovic Evolution Exhaust System and ESS have a special tune for this system. If you need any parts or question call RENN SPEC ask for Jason.
And never trust a salesman, most of them don't know shit about anything. They will said whatever it takes to get it sold. Tune and pulley will void the engine warranty. |

Your car will run just fine with the CEL on, it definitely won't run like shit. And the delete-r just sends a clear code to the ecu every ten minutes, so if it actually did run like shit, the delete-r wouldn't help you.

Tune would void warranty? I was just told by Mike with Powerchip that the tune would not affect warranty.
"Warranty should not be affected. The dealer should not be able to see that you have any changes in software, and your car will interact with the dealers systems the same way a stock car would." Thats what I was told. Powerchip has a very good reputation so I wouldn't think that he would say that just to sell his product. Can someone with a tune chime in in terms of warranty?

Just saying. The likelihood is low, but I figure you should know that the possibility exists. Just like how my doctor told me that the possibility of me losing feeling in my jaw existed since my wisdom teeth were impacted and heavily infected near my nerves. Did I lose any feeling? Nope, still hurts like a fucking bitch. But he told me about the possibility anyways. |

Haha, I like the analogy.
Well, I have a good relationship with my SA so I will probably talk it over with him first and see what he says. I would really like a tune though, I need to wake this damn car up!

Primary Cat Delete in my experience (dyno verified) without appropriate tuning results in lean fuel mixtures (like 14:1). The impact of HFCs on fuel mixtures will be less, but still you should really have a tune designed for a high flow exhaust system.
I guess BMW could argue that removing the HFCs could screw with the tune but the ECU is very powerful and dynamically adapts to most adverse conditions. |
