I am looking to replace my E89 30i exhaust system. Looking for a full straight through system if possible and not just a back box. I'm not really after more power although I know performance exhausts often bump it up 5 to 10 bhp - I want my car to breath a little easier and to save some weight with a nice throaty (not to load) sound. In the BMW M135i now 140i territory.
I would very much appreciate hearing from anyone who has done this about they're choice of brand and the overall experience of fitting and before and after the swap.
Much appreciated!
Thanks
Stu
