Don't worry guys I've been doing this a while
There will not be and sound clips this time around. We just don't have any more time with this car, so we don't have the time to swap it all around. And we also build a silencer that is an appropriate sound level for pairing with cats, so if we ran it for you with the stock cats it would be fairly quiet

It's just the diffuser portion which looks to be expensive. We may be able to produce that part elsewhere, or come up with an alternative that makes it feasible.
Had the chance to shoot some sound clips for you on Friday. Couple quick ones on the way from my house to the racetrack where we were doing some track testing of the VelocityAP lowering springs, as well as durability and heat dissipation testing on the V8 headers. Several hard run on-track sessions this weekend.
This car has been fitted with our 'Touring' sound level silencer, which is our quietest standard sound level but when fitted with the sport cats as on this car it is still fairly aggressive. Quieter and more refined than 200 cell cats with the stock exhaust and valves open but that was the idea is to bring the sound level to a reasonable setup when paired with sport cats.
For those just fitting an exhaust, probably Supersport will be the way to go for fixed sound level. Tried to drive the car both hard and at cruise, different levels of throttle to give a good idea of the breadth of sound, rather than just ragging it hard all the time.
It's hard to convey with video sometimes but a couple of things to note - the sound quality is much better with this muffler than just with 200 cell cats - the smoothness and tonal quality of the exhaust note is much nicer. Also, although the exhaust does sound loud in cabin on the video clips, if you notice that on cruising throttle the mic actually pics up road noise and you can't hear the exhaust much if at all. That's true in person too. At 100kph/60mph on steady throttle the road noise overpowers the exhaust so in spite of the raucous acceleration you still have civil cruising if you want it. That's one of the hallmarks of our uniquely constructed muffler setups.
Unfortunately we were stuck on the short course because heavy rain had washed out parts of the long course (very new track and grass hasn't grown in yet. But here's the full course:
Had a number of messages and emails about the launch special. Retail pricing on these systems will be $1895 for fixed sound levels (Supersport, Sport and Touring) and $2595 for valved (Race Straight Pipes + Sound level of your choice.)
Launch pricing will be limited in quantity and will be $1200 for fixed sound levels and $1700 for Valved.
We will be doing final sign off on the exhaust probably end of this week and starting production in a couple of weeks (need to bulk order the tail trims.)
It's looking really good Stuart. Can't wait to hear it in person. I'm sure I'll have a nice soundtrack to listen to on my drive back. Here's hoping the weather cooperates.
Just a quick video from the other night, will post some more.
Bear in mind this is the 'Supersport' with the 200 cell sport cats so it's pretty aggressive. I think the Supersport or Sport with standard cats will be in the daily driver range, and probably Touring for those with cats fitted.
