Hi guys, would you like to ask if you could get a little more sound out of my Audi 80 Type 89 (90hp) without great investments. I already pulled out a Bosi sports pot, sports air filter K&N and the hose from the air filter box. If the engine is warm (90-100 degrees) it sounds quite good (feeling light). However, in the cold state the sports exhaust sounds strangely equal to zero (hears almost like such a Japanese sewing machine). h do what???? Greetings Chilly
