I've had them for over 2 years with no issues. Like someone said above, combine them with other mods and you will see a big difference.

UDPs

I installed them on a '97 & a '00 GT. I didn't have any problems, but I didn't notice any benefit either.
When I got my '06 GT, I decided not to put them on. I weighed the hassle of installing, the risk of messing something up that was working perfectly now and also remembering some of the horror stories about installs gone bad and decided to leave well enough alone.

Anyone installed these with headers and cmdp's? I plan to install the udp's and billet cmdp's with borla lt headers so we will see what kind of results that brings. I havent heard of any overheating problems before with the pullies but reading these posts kind of scares me now...

If I could get more confirmations of these kinds of stories, I may be more inclined to get UDPs myself.

those numbers kinda seem to be within the margin of error........but it does make sense. hard to take them at face value, but a valid point nonetheless.
