Hey, im looking at buying an A4 B5 2.8 Quattro sport, new to the Audi world im wondering wot these engines are like for tuning and wot gains to expect? Will do the usual with air filter, exhaust and chip, but is that my limit to keeping the budget low? Wont be supercharging or goin forced ind route. Also, excuse my lack of knowledge, but can the exhaust be made custom by anybody and wot happens with resonators etc that are in these type of cars, can they just be removed, if so are there benefits? Any info appreciated, cheers.
