Wow that sounds amazing! With the valves closed it actually seems pretty quiet. If it were me though, I'd drive around with it open all the time! Did you notice any difference in performance having changed your exhaust?
My XFR is also Polaris White like yours, except you have different hood louvers. I have thought about having mine painted black or maybe getting the Mina Gallery carbon fiber ones. What does your car have? They look very nice.

You went to the right place, Alan is great, that's where I got my work done. I have used him for my past 3 cars. Give him a call and ask about the white Jaguar sedan that got the X pipe done and he will know what to do. Since your's is the 3.0 supercharged, doing the X pipe will make it sound close to the F Type V6 S and that car has one of the best V6 exhaust notes I have ever heard!

Throttle feels slightly sharper when I have the valves fully open and I feel a bit more torque when I have them fully closed (Take this with a grain of salt, might be placebo). For the best performance improvement, place the X pipe up front right after the cat converter and for best sound improvement, further back on the midpipe.
I bought mine CPO and the dealer told me the hood louvres were OEM carbon fiber pieces put on by the previous owner. I don't know how true that is, if he was being honest, they retailed for $1200. OEM or not they look really good and I get a lot of compliments on those.

I don't know where he races but I race at several places and do several different kinds of racing and I am required to have a current rated helmet at the very least. In the states we follow the Snell ratings which means your helmet can only be so old before it requires replacement even if it never saw any impacts.
Sometimes fire retardant gloves,shoes,pants,shirt are required.
I have also been barred from running over certain speeds without a full roll cage and fire suppression system installed.
Bonneville salt flats in particular but only if your in certified competition. On your own you can run what you want at the salt. Problem is the surface. If you run during speed week they have dragged the salt to help smooth it out some. Otherwise it's pretty bumpy at 150 MPH+.

Except that it was an H-pipe rather than an X-pipe, on the advice of my exhaust specialist.

So you completely eliminated the muffler looks like. From what I understand the further back the x-pipe placement the louder the exhaust note.
Does it make a funny noise or wrrasp around 2500-3500rpm? I ask this because I got a x-pipe with just resonators and it sounded like I was driving a damn Honda Civic through that range. Just curious.
