Hmmm, I've tried to read that post and tried to put in some commas and full stops where they seem appropriate.....
I think the original exhaust was replaced. And someone drilled out the cat from his exhaust? (I didn't even know that rather large section of exhaust could be "drilled out" )

And the dump valve is releasing air through the revs rather than in between. I think this means the valve is leaking under pressure rather than releasing when the throttle is lifted.

Other than that I haven't a clue.

OP, please come back and add some punctuation, spelling, and sentence construction. Once we know what the problem is we may be able to help.

Glad to see that I was not alone trying to interpret what the post was all about.
