Here is a cold start - I recorded it at 7:30 am, so I couldn't rev it up without waking everyone up...
We recorded on track audio this weekend - should have video/sound shortly.

Here is a comparison of the tips after a few heat cycles on track. It looks like Jamie and the gang were able to roll the tips over so it's not just an end cut. It was a really great and unexpected result!

What gain claims (torque and HP) are they making for $20K and a 10kg weight difference?
Will they guarantee the cat material will hold up at track induced temperatures
I haven't bothered with race headers etc on high power and torque NA cars because the gains without a tune are minimal. Moreover, when I speak to people in that part of the aftermarket world and you start asking about who did the the gas flow design and what difference did it make to inertial and wave scavenging they usually run a mile. At that price point I'd expect answers not just a dyno plot.
Dunno, maybe these guys are different. At that price point I'd expect them to be...

Couple data points.. only did a couple pulls with the exhaust.. it makes power. Same stretch of road, not sure why slopes are different usually its 0%. Most noticeable bump is in the mid range tq and throttle response. It lights up the tires on demand
