I need to replace my exhaust system and the last time I look here on the forum, the opinion was that a Miltek centre section, non cat, and OEM rear box was the best setup. Is this still correct ------------- Ian (EGO) E30 M3 |

I fitted a Supersprint rear box. Doesn't sound too loud. Much cheaper than a OEM one. ------------- Robert |

Thanks Robert. I used to find the Supersprint a bit noisy for competition outings. I like to be below 90db or just over. Where is everyone? This forum used to be buzzing. ------------- Ian (EGO) E30 M3 |

MillteK centre section with OEM rear box will not work as the Milltek centre goes 2-1 after the downpipe and runs a larger single pipe into the Milltek rear box which has 2 outlet pipes so your OEM rear box will not mate with the Milltek centre as it has 2 inlet pipes. -------------

you can use a Supersprint STREET middle section with the OEM back box. But it's mild steel only and not louder than stock (tiny bit maybe) A Eisenmann back box is a good choice as well, but pricey. Is 304 Stainless. Why do you need to replace the exhaust system? Cracked? Broken? ------------- E61 520d, slow and buzzy but my wallet likes the mpg..... |

Thanks guys for the information. Millteks a no then Sporty1. UweM3, the rear muffler has had a split in it for over a year and I keep plugging it. Now I think it's time to spend out as this one has lasted 11 years. The centre section is original and I had the cats removed some years ago. I'm just looking for spares before they all go "no longer available" Kind regards guys ------------- Ian (EGO) E30 M3 |

A complete Milltek system will work, but not a mix and match. It is as Uwe says above.
