My car is making a *thud* *thud* *thud* sound... is it my ACT clutch?
I got a clutch installed last week - only recently did this sound start occuring, so I'm not sure if it's the clutch, but it's the only thing I've recently touched on my car.
Basically, I'll hear a *thud* *thud* *thud* sound that appears to be in sync with my idle. I have cams, so I can definitely tell it's in sync (and not just random). I can only hear it from INSIDE the cabin, not from outside, and it sounds like something is thudding against the frame/chassis of the car. It's a very dull sound, not like a clang, so I know it's not metal against metal. At first I thought maybe it was part of my exhaust thudding against the bottom of the car (I recently switched out my HF cat for a test pipe), but when I looked underneath it looked like there was a lot of clearance between the exhaust and the chassis.
This could be a normal sound of the ACT clutch - but this is my first aftermarket clutch, so I don't know if I should be expecting these sounds.
Any ideas?

It only seems to happen at idle - either that, or I can't hear it when the car is actually moving. Happens occasionally while turning, but most often reproducible when at idle, or when starting to move from a stop (1st or reverse).
I will have to ask ISP racing to figure out what the problem is...

same here. My stock TOB did that too, and even the new one.
