Hello all
I have just bought a very nice 1987 non cat e30 m3 to replace the evo 2 I foolishly sold 3 years ago. It is totally standard with the exception of the exhaust system I believe the exhaust is standard bmw with a scorpian back box but it is possible it could be a full scorpian system. What is the best option for replacing this - I would like to return the car to standard but at £378 for a BMW back box the prices are a bit punchy! Please can you advise what the best way forward is thanks Keith |

there are loads and loads and........ of threads on this, but IMHO (& some others ) the best replacement for a standard system is Miltek.

Miltek is maybe the best value for money system. Just don't forget to mention the problems they had with the centre box.... I would go for Supersprint centre and BMW back box Or Supersprint centre with Supersprint back box Can you not weld the current back box you have? I remember welding my OEM backbox 5 times before I called it a day and bought a used Eisenmann Edited by UweM3 |

The first batch of Milteks appeared to have a problem. I believe I was one of the first to have it fitted (August 2003) to a daily road-going E30 M3, so after a while the centre box cracked. It was replaced (June 2004) under warranty FOC by them - and fitted at their base. Over a year later (November 2005) I had a slight blow in the centre box, but again it was replaced FOC with no problem with their Mk3 version. Since then it has been fine - so IMHO the early problems have been fixed. If you're using the car as a normal road-car then I don't think you can do better, it's not noisy, and it's warranty repaired all the time you own the car.

I'd go for the Supersprint centre section and standard back box. Ive had 3 Miltek centre sections and all have had issues so rather then mess about again I replaced with supersprint. I did go for a hartge back box though.

I think drilling a smal hole at the deepest point will help to let the condensation drain out and prevent rusting. Or get a Stainless Steel backbox. |
