supersprint cost are very high!
I've request for downpipes and they want 2200€ only for it (about 3400$):eyebulge::eyebulge:.....I don't know if the American price are different,but in Italy are absurdities!!!!!
Moreover I had complete SS exhaust in the 130i and the sound was the same than stock
The increment of hp is about 10-15hp and for the Italian price of complete system(about 6000€ or 9000$) it doesn't have sense!!!
I suggest to waiting for other exhaust system of other producer that will be the same increment but for a price of about 2000$ for exhaust complete of downpipes!!:wink:
