It depends...
Serious track rat, in a hot climate, maybe...
Street driven, occasional track day, likely not...
In the race system the biggest heat generator, the cat, is removed so already there's less heat than in the stock system.
The thing with all the coatings is the break in required to make them last. If you're not gonna break it in, don't bother, it will likely crack.
Break in involves disabling the secondary air pump to reduce the temperature ramp in the exhaust due to the cat warm up cycle. Then slowly warming up the headers and cooling them back off. Idling then off, idling heat up a bit more off, repeat many times etc...
If you're patient then can be helpful and will last, but we're not 100% that it's necessary...

No secondary air pump here, but Charles mentioned the possibility of tuning out the fuel based catalyst warmup.

Anybody on the fence, you should think about pulling the trigger. We have a few dealers in Canada and Chicago area that are pushing, once we reach 20, the GB price is full...

A tip for dealing with PayPal, as they really don't want you to charge to CC.
The same CC that they rejected was successful after logging in and setting an additional payment method for CC.
Took me several days to figure it out after calling my bank.

Jamie,
I am interested, however, I have only 700 miles on my GT4 (not even properly broken in) and live in Tyler, Texas (100 miles east of Dallas) and do not have a lift and have a GT3RS. So I cannot decide what to do!!
