I'd truely recommend Dinan products........even I have friends arguing about German car with American parts??, but I still find they are very good, and pricy as well
if maxbimmer have another me or we get chance in Spring, I'll show u what's the diff after I've done the CAI, Exhaust, and chip
but, do u really want faster or u want to look more eyes killing and more attraction from guys&gals on the street?(well, it's the best if you can afford both, but............$$$$$)
well, before you go any further in performance mod., just think again, and see what is u really want?
with performance mod., if your budget is under $20k, then I wouldn't recommend, because without a big budget, it won't make ur car much faster..................and if you want it more sportier, just try the exhaust
