Bringing this back from the dead since I was thinking of doing the same. OP how is everything holding up with your setup?

wow this is pretty sweet and a great way to keep me and the wife happy (she likes it quite but I like it loud). where did you order the electric cut out? I would need a 3" Y-pipe right? 2014 335i with stock exhaust.

Dope! Do you feel a loss on the low end and a better top end?

Dinan_Rated · 05-12-2017, 02:41 PM

Nothing?

I ended up making my j pipes have a dual purpose installing dual manual dump valves, burble tune and the sound is amazing!

I also haven't mounted the switch yet because I want to make sure I want to keep this before I cut a hole in my trim. I'm about $250 into the project and having the flexibility to have my car quiet is what really intrigued me. Plus when I can finally get my car on a dyno, I'll be able to put the back pressure debate to rest.

I haven't driven it yet but here's the first startup video....

Also, the cutout looks low but it really only hangs down about 1/2" more than the lowest part of the exhaust and you can't see it unless you bend down....

Updated with a video of some drive bys and acceleration...

hey Mike is your set up with stock downpipes and stock exhuast with a cut out ?

mikew2069 · 01-14-2019, 07:36 PM

I have HFC dps and stock exhaust. I've had this setup for a few years now and everything is great. I did have to rebuild the cutout motor once but it was very easy to do.

Can you tell me where you purchased the slide gate cutout? I can only find butterfly cutouts.

Can't remember exactly where I purchased it from but the brand is Doug's. I'm actually thinking about taking mine off since my wife drives this car now and she never uses the cutouts.

Let me know if you are interested in selling it.
