PE Mod and VRSF Catless downpipe clips

I figured I would upload the clips I had from my car, that way it might help anyone looking for exhaust modifications to see if they like this configuration or not.

I included a video of the different revving sounds comparing the before and after and another video with drive-bys of the final setup.

Mods while clips were taken:

MHD Stage 2+ (Medium Burbles for 0.7 seconds)
ETS Charge Pipe
ETS 7" FMIC
BMS Cold Air Intake
VRSF 3.5" Catless Downpipe
Homemade Performance Exhaust Mod
GFB DV+
xDelete (xDrive was off)

You car looks great, it is so clean! Did you find that your exhaust mods sound very similar to mine? I mean it should but I am still curious to know!

For the Diverter Valve, unless you are upgrading turbos or you have an issue with the one you have right now, it really isn't worth changing it.

I wouldn't even call it upgrading to the DV+ because on stock turbos and OTS tunes, it acts extremely similarly to the stock diverter valve. It is true that when I look at my Boost curves it is in average always slightly higher than with the stock DV, but it's such a small difference that it doesn't really affect anything.

The only reason I got the DV+ was because I had a compressor surge and had to change my DV, so I said might as-well!

As much as it is a pretty cheap part to upgrade, I don't think it is worth because of the fact that it doesn't really advantage you and that it is extremely annoying to install.

Here's a short clip of some revs, I absolutely love the sound of it. Only thing I would consider changing is deleting secondary cats but I'm nervous to mess with it because I like the sound a lot already

Sound very similar to mine, I love it so much hahaha. Nice plate by the way hahaha. I heard that deleting secondary cats would make it more raspy and drone so I figured I really didn't want to mess arround trying to fix droning. Our setup right now sounds awesome and is absolutly in no way droning or disturbing.

I think the xdrives still have the secondary cats. I know my RWD car doesn't have them though

Do the secondary cats do a good job at keeping the smell down?

If I recall, when I first did downpipes I could smell them a little but I do not recall smelling anything for a long time, even after the secondary was removed.
