Hey guys,
i havent boosted my car hard for a few weeks, and noticed when i do boot it, the car loses power and surges a small amount, i have more power on slight throttle than 1/4 1/2 and wot. the exhaust has gotten noticeably louder from the tip, and has backfiring on de-accelerating. You can hear the differences from the turbine at different throttle positions, so i am guessing it is still boosting fine. I have an inkling it could be that the cat has let go and caused a restriction? obviously i would check it myself, but one of the bolts for the cat are tight and is almost impossible to get to without a hoist and the right tools.
edit: The exhaust sound is clean, and it doesn't want to rev quickly in neutral like it should
I've searched online and called some friends but no real answer.
