Great product / Great service

I know this Mil-Spec cat is next best thing to test-pipe (not legal for street), I sourced at least 5 of these units so far, and one was failed (internal structure collapsed and block the exhaust) at EVO IX GSR. I saw the pictures to MAP so that they can discuss this with Mil-Spec, and they said this was first time to see this kind of failure. They asked about the conditions of the car, and it was stock turbo/stock engine/stock boost level, so nothing was out of ordinary.

They sent me two replacements (because one of the two units I bought together failed), and they even covered international shipping for me!

I had a strong belief in Mil-spec, but now I can say I can buy theirs with great confidence all the time! Highly recommended!
