ok im new to AF but i have been reading more than writing and was wondering what or where the numbers you guys keep refrencing to for the DV like the 710n where the hell can i find one of those and is it a dealer specific part? is the audi tt DV more audible then the 2002 1.8t? or b6 if im correct on termenology

 

The part number is stamped on the dv, the last letter is N on the 225 dv. No, it is not more audiable

 

so then which DV is more audible then a stock one for a stock vehical

 

An aftermarket piston dv or for more a forge splitter
