doubt its got anything to do with your exhaust.

its the back box that makes the noise. the loudest being the vortex afterburner or blitz nur spec-r

decat would make **** all difference in sound apart from you can hear the turbo spool up quicker due to the fact that you no longer have the heat shield around the down pipe.

The problem you talk about your engine nearly stalling sounds like a vta dump valve problem, if you have one take it off and put standard one back on.

hope this helps

is it a 99 or 00 and you disconnected the battery whilst changing exhaust?
