Like most have said, the DP adds some volume but not a ton. I would still recommend this exhaust as it’s plenty quiet in comfort mode and quite loud in sport! More video to come. Sorry for wind. **I may be crazy, but I did the install myself and think a downpipe is easier than the damn catback, solo**

I think this is what people spending $2700+ on the magnaflow want theirs to sound like :):)

Quick question I read on forums that the injen exhaust has valve rattle true ? Also is there any annoying drone inside ?

certainly is on cold start! Zero in either mode once the car is warmed up. Let me
Report back on drone! There is a little in sport mode, but I haven’t been on the highway in comfort mode yet. The difference with the valve open/close is stark, even without the downpipe it was significant inside and outside of the car…even more so with the DP

funny how similar they are, honestly! Do you have a muffler on both sides? Injen isnt modular so you have two straight through mufflers, but everything under the car is 3.5”. The difference in sport and comfort is very similar to yours as well!

I'm running a muffler on the non valved side and straight pipe on the valved side. So there's a much bigger difference with the valve open.
