Default Loud metal clunk after ACT 6-puck install

I finally got around to getting my new clutch in. I finally put 500 miles on it and decided to test it out. It grips like crazy but I noticed a weird problem.

When in first gear at a roll say like 5mph and I floor it when I let off to shift into second I get a HUGE metal slap, it sounds like from the front passenger side. If I launch the car it does not do it when I shift into second and it doesn't due it into anyother gear. It also is when I only shift hard.

I thought maybe it was an IC pipe since the unsprung disk makes the drivetrain shock alot. So it took some floor put it on IC pipes took for a ride and came back to see if made contact anywhere but it didn't. I did also notice the rearend clunks alot now, which it never did before so I guess its time for some TIC bushings.

Anyways did anyone else ever get this from a ACT clutch or from anything else? It is a very loud and hard thud like a really hard clunk from the rear only its in the front and I can feel it in my seat.

Thanks

I would check the downpipe and midpipe brackets. Also, some people have said that the outrigger bushing clunk sounds like it's coming from under the seat.

I get a clunk under my car too. I have an ACT clutch and notice it when I stop and go slowly. Its not continuous, just one loud clunk and then it goes away. I can't always reproduce it so when I took it to the mechanic, of course it didn't do it. I thought maybe it was the exhaust hitting something and if I do shake my exhaust vigorously I can get it to hit, but I doubt thats what is happening from such a low low speed. Let me know what you find, it might be the answer to my issue.
