Should be notably more raspy with headers or gutted cats..
Here are some cold start clips with flap closed and open on my car with stock headers.
As a point of reference, with the flap closed, it sounds exactly like stock maybe very slightly louder.
Flap closed (cold start): Varex exhaust (closed flap) on Lexus ISF - YouTube
Flap open (cold start) Varex exhaust (open flap) on Lexus ISF - YouTube

Have not had time to take some good clips, but here are a couple from inside the cabin with windows down on a local street..no room for spirited runs.
While filming this I noticed I have a leak at one of the connections on the right side. It is only apparent at WOT when the flap is in the closed position, I assume because the exhaust flow is more restricted and under higher pressure than when the flap is open. IT is also quieter (so it is easier to hear). I need to get that tightened up.

That's no where close to straight pipe sound lol that's the reason I bought the varex version to get the "straight pipe" sound.you still can hear the motor over the varex open and my muffler delete is louder than the varex.. I'm gonna weld straight pipe where the resonator is at and hopefully that makes it louder. I'm might sell and get the a ppe exhaust.

Lol!
When I said straight pipe, I meant the restrictive sense, not sound wise. The Varex is definitely not a loud exhaust in open position. Sounds to me like the non varex and borla vids I have heard. It was also quieter at low rpm than the muffler delete I had previously. But for me, the muffler delete was too loud at the low RPM. It's all about prersonal preference.
When closed it feels like it is being restricted..I think it is fine for normal driving, but it will definitely hurt performance in the closed position.

From everyones reviews it seems like the varex in the open position might be too quiet for me. It almost makes more sense for me to get the non varex version and save some money. I have headers which might make it louder. Anyone with headers running the xforce exhausts?
