as title reads was fitted today im not sure if this is a problem but i had my music turned down so i could listen to hear any changes in exhaust note which there is a little but i heard pretty much where my gear selector is a sound of like a whistle under acceleration is this right for a hi flo cat or not and also cant see any difference in low down power maybe better acceleration when accelerating from 80k up. does all this sound about right.

when mine was fitted, there was no difference for a bit and then after a while i noticed a change. i think the ecu needs to re learn it self again

Yeh my high flow cat made the same sort of whoosing noise under hard acceleration

You'll probably find that 'stink' is exhaust sealant.
