'13 F31 320i upgrades
Hi,
I've got a 2013 F31 320i. I've been running BM3 stage 1 for almost a year now, with great results. However, I would like a bit more oomph. I haven't planned to put too much money into it, but following the stage 2 recipe in the BM3 app, I require a full exhaust & upgraded intercooler to carry on further. The problem is that for most exhaust I find on ebay, the shipping cost would be the same as the cost for the exhaust. I seem to however have found a workaround solution, if possible. Does anyone know if an aftermarket 335i/435i exhaust would fit with just replacing the rear diffuser? The exhaust I'm planning on buying is this: catback downpipe or a wagner branded one Coupled with a chinesium intercooler or a wagner branded one Any ideas if this would work bolt on? |

In my opinion, if the fuel quality is not good, the 20i stage1 and stage2 will not improve much, but the risk will increase a lot.
Replacement with larger intercooler helpful |
