Hi guys,
I have a 2011 135i (n55). I purchased a Kies 1M replica bumper and getting the exhaust correct has been a nightmare. I have been trying to avoid the costly battery relocation mod. I purchased a remus quad exhaust system but it appears the Kies diffuser has, what I assume to be, 1M exhaust fitment. Because of this the system fits fine.... without the diffuser on and looks very goofy. Has anyone had similar issues with trying to do a "lazy" rear end 1M conversion? I have seen some people do this conversion without the battery relocation but they all seem to have muffler deletes. I have no idea how loud this will be but I live in an older populated, small residential area and do not feel like having angry neighbors. Current set up is the remus quad exhaust and stock res, stock DP.
Any insight would be greatly appreciated in regards to diffuser solutions, exhaust solutions, or about N55 with muffler delete and quad tips in terms of sound pollution.
Side note: May be listing a nearly brand new Remus 135i Quad exhaust with the "race" tips for RRP.
