1986 BMW 635 CSi (E24 Sharknose) - Drive Along (Custom Exhaust + Reprogrammed ECU)

[@rudi_ghuliani]

What a delight! I learned to drive in an e24 manual, absolutely loved that car. Yours sounds fantastic; that M30 is a silky smooth engine!

Sounds awesome. Did you have to reprogramm the ecu after deleting the cat?

[@slownrusty]

Thanks, no reprogram after the cat delete as these are pre OBD cars

[@cvk197333]

Sounds great! did you delete the cat? and whats the offset on those wheels?

[@slownrusty]

Thank-you! Yes the cat has been deleted. Wheels are square 17x9 but with 25mm spacers rear and 15mm spacers front.

@@slownrusty the spacers make all the difference! I wondered because I can’t find a wheel with an ET of less than 15 and I want the wheels a bit more flush on my 635. I deleted my cat and have tried 2 or 3 exhaust configurations but I had a difficult time with excessive drone at 2000RPM until a finally built in a quarter wave resonator…have you noticed any drone in your setup??

@@cvk197333 - Its tough finding an ET lower than +15, I tried looking for months as well all over the world and did not want to spend huge $$ on a custom made set. I don't have a drone in my set-up, very happy with the way it sounds.
