I recently installed the new "H" version mufflers on my 2015 IS350 Fsport. According to Invidia USA, it is 15-20% louder than the previous mufflers. I only made some short video clips from my iPhone of axelback only, full catback cold start and full catback with revs. Enjoy!

wow so much more aggressive than the older version...I wonder if there's any drone inside the cabin.

 

I have the full exhaust so it drones a bit from 20-40 MPH, but goes away thereafter. I love the backfires and pops though

 

I like the way that sounds but that exhaust note would be too loud for me as a city daily driver. Cel vids are hard to transfer its volume and tone. You'd really have to hear it in person.

 

Sounds good !!! Glad you went the Invidia route.

Sounds good! Is yours paired with the stock midpipe?

 

Do you have a videos inside the car? I really want to know how much more drone you got comparing to the older version

 

The first two clips were just with stock midpipe. Currently I have the full cat-back (midpipe and mufllers)

I'll post some videos soon (fly-bys and interior), but it will be phone camera quality.

 

wow sounds freakin mean
