Hello all. So I have been immersing myself in all things e92 as of late and have a path I'd like to pursue with my vehicle. Not sure if anyone has attempted it though. Over the next few weeks I plan on installing the following:

-BMS Intake
-JB4
-VRSF 3.5" Catless Downpipe

Muffler is the kicker. I'd like to do the PE Mod, but only to the LEFT exhaust muffler, with the right muffler still having the stock perforated pipe. Reason being is I'd like the idea to control the valve on the fly without opening the trunk and also having a stock tone (via a system like the Exhaust Meister with garage door control) when driving under 3k RPMs.

Questions:

1) Is this a good idea to pursue? I'm limited to exhaust options due to my vehicle being AWD (also having secondary cats), so this is really sounds like a better idea the more I think about it. Not to mention there would be a significant cost savings over buying an aftermarket exhaust.

2) Would there be any adverse issues to running a system like this? Perhaps harmonics would improve with the combining of PE Mod and stock mufflers lol?

If anyone has any input or advice I'd love to hear it. Thanks

I guess it' be 80% louder.
You can always do the right side later if you find it not loud enough.

When I didn’t have downpipe, it didn’t make too much difference but after I’ve installed downpipe it sure did make a big difference. 😁

Any video clips? I'd be curious to hear what that set up sounds like.

I have one clip that I uploaded before the downpipe. But I will upload a new one tomorrow so you can hear the difference after downpipe.

Interested in hearing post DP as well since I'll be doing the PE mod/DP install together. The clip you posted, that's with the PE mod on the left?

Awesome video man, thanks for taking the time to upload it. I've decided this is the route I'd like to go.

Very nice! I was planning on doing this also and that video confirmed it. It can be nice and quiet when cruising on the highway, but get some growl when you want to have some fun. Best of both worlds!
