Active Autowerke v Valvetronic equal length exhaust systems
Just wondering if anyone has any knowledge on the two, which is actually better and why?
I understand the EL gives you a deeper smoother tone? Correct me if I’m wrong. I have a g80 M3CS in order and this is the ONLY mod I’ll be doing this time round, so I want to make sure it’s the correct one. |

Tone, design, price, and quality are different. AA is US-made and has a higher standard of fabrication. Valvetronic seems to have more of a VQ motor sound than AA. AA requires cuts to the midpipe (not sure about Valvetronic). I went with AA and am glad I did. Quality definitely seems to be superior.
EL certainly gives a deeper, smoother tone, and helps eliminate rasp - regardless of which company you go with. |

The main difference is the style. AA is an X pipe whereas Valvetronic is a single midpipe. I’m not a fan of the single midpipe design so I’ll be going with AA, it’s all personal preference though. I don’t think there is any data to support one being objectively better than the other.

What I meant by X pipe vs. single is the AA only has one crossover point but the Valvetronic merges into a single pipe after the downpipes.

I look at some of your videos, you went for the loud all the time setup. Car sounds mean.

It may be, but anything backing that up, materials testing… user reports? Or is it just, you like what you have and are now saying it’s better? I heard that valvetronic is just sourcing alibaba stuff and rebranding it, and that it rusted for a guy in about 6months and the company offered him a discount instead of a replacement / refund. So, I’m no VT fanboi but would like to know if you had some actual info or if that was just your guess. |

You saying it sounds better than AA full system? Or just better than AA equivalent mid pipe ?

Some people pointed out some similarities in the welds and noticed AA doesnt say the midpipe is made in Miami like a lot of their other products. |

How hard is it to get confirmation. I guess the companies not saying anything is confirming that it’s all alibaba parts. Valvetronic stuff does sound amazing though. |
