which one do you perfer?

cuz ive heard alot of good things about both but more alot of good things about the borla. and it seems like alot more people have borla or are getting it.

and does anyone know how many HP does the Eisenmann race exhaust produce? i believe the borla produces 12 HP.

oh and im asking which is better for the E46 M3. thanks in advance!

I have Borla and really love it. I do feel the extra HP gain fromthis system. They have a little chart on Turner's page about a backpressure comparo between borla nd esies that you might want to check it out. I would go w/borla if you want to save some $$

what are the advantages of borla over eisenman besides money. and vise versa?
