I have their other kit with the gt3582r and I've had it for 25000+ miles and 2.5 years with no issues so I'm sure they are doing fine. several people have had their initial kit for a couple years now with no issues.

Running great! I highly recommend this kit. Only problem was a slight oil leak with an oil line but that wasn't IPS's fault. Had the line replaced and all has been well since.

I think I'll be saving up for this one... :-) and maybe a zl1 diff swap too...

We revised our kit a little bit. Now all black is standard option. All cold side piping is now powder coated in house satin black and all hot sides are ceramic coated in house with 2000 degree black ceramic powder. it is the same powder we use on our orange corvette race car.

Price at the store says 6700 but on here 6300? Also could this be mounted on long tubes?

You cannot use on longtubes.

No you cannot! But don't let that detour you, it is an easy fix with the stock manifolds or set of ARH shorties. I had the same thoughts way back when so went with a Whipple, but now it is at IPS getting the turbos!

there was a price revision

I can tell. I see the demand is higher so are the prices.
