Advice/Questions

Ok so I have a couple issues with exhaust mods and springs. I am currently on M-Sport springs and I love the feel and the lowered look but I'm currently not looking to get coils right now. If there are springs that can give me a lower look without risking handling. If not I don't mind buying coils. My second problem is, I want to go straight pipe, no muffler (I don't mind the drone I actually love it, daily drove a straight piped no muffler 1966 Mustang for awhile w/ 289 V8) But will I get enough back pressure? Or does anyone have experience with the modified OEM exhaust? (E90 is blocking out the name of the people who do it)

No back pressure needed, your turbo provides all that you need. A turbo is fine with a dump right after the turbo. For the springs you should head to the suspension section. Tons of write ups there for all the different options.

For suspension, check out the Bilstein kits. Similar ride quality to M-sport and should get the drop you are looking for: https://www.turnermotorsport.com/BMW...pring-packages

I feel like at that price I might as well as buy the coils.
