Does anyone have experience with the 200 cell HJS downpipe on the F20.

My car is a 116i , will it need a tune after a downpipe and how loud are these things ! on a stock exhaust.

Does it make sense just changing the downpipe and does it really increase hp. :?:

P.S These things are expensive :eek2:
