They gave me a hard time while making a purchase many years ago that gave me a bitter taste so I don't use them much, I have bought a few things over the years but their shipping prices are ridiculus so I use Jegs or Summit, I bought my TTI headers and some valve covers for my D150 from Todd at Marsh Performance and he was great to deal with, I will buy from him again.
