Hi,

Actually i find out the problem... the tubi exhaust sound more depp tone which is not what i was expecting.....

 

I think there may be a valve you can disconnect and really open the exhaust up, but i'm not certain

for many exhausts it takes several hundred - 1000 miles for the sound to "open up." I have had this experience on several cars and have never been disappointed.
