update: mod on 335 exhaust done PICS
OK, so while messing on some BMW forum, I learned that there's a small flap in the driver's side exhaust pipe that can be deactivated by simply unplugging a very very very accesible plug that is in the trunk area. This DIY mod makes the car sound the way it should! No need for exhaust system (2000K or so), unless you are a HP junkie and have a need for an extra 20 HP or so. (debatable).
FOR ALL BMW 335 OWNERS THIS IS A MUST. CANT MISS, HAVE TO READ:
"DIY: 335i Exhaust Sound Mod. Better, and even easier than golf tee mod.
OK I know I am not the first to do this, someone had to clue me in, but instead of plugging, crimping, or otherwise disconnecting the vacuum line under the car, just unplug the actuator in the trunk in front of the drivers side tail light. I was a little unclear as to how this works, but it's dead simple, easily reversible, and doesn't involve digging under the car. Win-Win!
So a big thanks to whomever it was that clued me in... I like the sound of the dual exhaust all the time without the bypass, but I also like being able to quiet it down if I am going on a long interstate drive... So here's a Barney Style Step by step to a better exhaust sound on demand."
Note - The actuator he's unplugging controls the vacuum that controls this valve.
OK, so step two. Custom sport inspired 4'' (dimisatips.com) diameter stainless tips with rolled edges (just like tips on my Tubi)
