Sifus,I'm new here, though have been browsing on and off since I got my udm - last of the E34s 5201 AB car.I need someone to look at my exhaust, it sounds boomy (leaking?) and power is down, especially on bottom acceleration. You guys keep mentioning this dude Jaafar, where is he (I'm near Sunway, so can find my way if got address)?thanks in advance.
