Just picked up a 135 :)
Hey gents,
Just bought myself a 135i and now waiting patiently for my mate to get back from the mines to give me the keys!. Had a e92 325 and sold it due to not driving it as I had a company car and to be honest was a bit slow for my liking haha been looking at cars for a long time now!, was looking at 335i as I loved the 3 series shape but my friend asked me if I wanted to buy his car, I couldn't say no due to the KMS that was on the car, barely gets driven as he is always up north, its an 08 with only 54000kms on the clock. Already purchased a few parts for the car, chargepipe, hks bov and MHD tune with cables etc as I have always had a mog bug when buying new cars lol Now deciding what to do next! My mate does have an exhaust system that he hasn't put on and asked if I wanted to buy it BUT I have been told on these cars an exhaust is mainly for sound? Should I ditch that idea and go for downpipes and intercooler? Car is going to be a weekend car and daily use, prefer performance, will do blacklines and maybe a 1m bumper later down the track Will post pics up soon of the car Any help would be great guys as I am new to the turbo world |

Welcome dude! Sounds like you're on the right path so far in terms of mods.
As for the axleback exhaust, yes it's purely for sound. Power is going to picked up with catless or highflow downpipes with a larger 3" diameter and a corresponding tune that accommodates for the higher flow. Changing the downpipes will also increase the volume and change the tone. If you want just some extra volume you could just crimp the little vacuum hose that closes the flapper valve inside the exhaust. Or you could pull the wire inside the boot trim lining. Both ways work and are completely reversible. That does however tend to add a bit of drone though. Getting a larger and more efficient FMIC wont necessarily add more power, however it will help make the car a bit more reliable in terms of performance as you'll get less heat soak. I'd still recommend getting one if you're planning on tuning the car and going with other bolt ons.

Welcome to the 135i club! Sounds like you picked up a nice low km car.
I agree that downpipes and FMIC are probably next on your list. If you're bumping up the power with MHD make sure the car is reliable first. New spark plugs and coil packs are highly recommended. Keep an eye on the stock injectors, water pump and high pressure fuel pump too. If well maintained these can be very fun and reliable cars!

yeah Im pretty sure the exhaust he has is an axle back. Thanks for the advice, will keep that in mind. As just being a daily driver would you say stock FMIC would be ok? I know occasionally I will be doing the hard pull here and there but again just a daily |

Ive actually picked up some new spark plugs and coil packs today! haha Im thinking for now possibly just doing the downpipes and leaving the stock intercooler for now as I have heard a lot of people running them just for a daily. May do inlets and CAI for better flow to? |

Definitely do downpipes and inlets together, as the DP's need to be removed to install the rear inlet

But would be smarter to do both at the same time to reduce install costs |

Would you be able to suggest good inlets with using the stock turbos? Been looking at VRSF and VTT, any suggestions would be great |

Difficult to compare cars, but I pulled 316rwkw FBO E50 (no inlets) and Marty on the same day pulled by memory 330rwkw on FBO PI E85 with VTT inlets (both with stock turbos) |

Sweet, good to know, I may plan to get a FMIC but in time, especially if I am not needing it for daily use |

I had been on the advan dyno three times prior:
stock with procede tune: FBO with low boost map: E30 with cobb OTS map: I would guesstimate my car would have made 260-270ish rwkw on FBO high boost 98 (never did dyno it in this guise prior to going E85) |

My aim would be around the 400hp mark without e85 but 350 360 would still be a weapon for a daily lol but 400hp would be better hahaha |
