I spent $600 for my stainless steel Borla dual pipe system for my 2003 mustang Cobra a few years back and thought that was high at the time.
The reason I say 500 is a good deal for the berk is because spending $1500+ for an axleback is just crazy...but if ya want to spend the bux no biggie...My exhaust sounds great so I am happy
There are some other decent price alternatives out there...maddad, BMW performance etc...I am glad we all have choices and dont sound the same
Thanks
