Ive got a full mongoose 3inch through with centre removed and 4inch pipe andits far to noisey And also think it looks too big

Would love to change to a 3.5 inch tail but its not worth the hassle+ive been told the one ive got is the one to have

Its a fookin nightmare in the morning and on long journeys

But they are all noisey no matter what , i think

And has to rolled out lol , anything else looks shit
