Prices?

I already asked on one of my other threads about exhaust for my v6 1999 mustang but I now need prices. I want the low pitch rumble like a V8 and dual exhaust instead of single. Ive heard three different types of exhausts...
Flowmaster super 40 series
Magnaflow
Bassani
How much would it be to get the exhaust plus labor? Im pretty sure I would need a different exhaust manifold.
I really want exhaust just need to prices

i paid $350 for my 40 series flowmasters installed and a coustom h-pipe. but i already had 1 muffler...

i have a dual MAC exhaust for 99-04 GT's but i totaled my car before gettin a chance to install them. if they can be fit in ur car i will sell them to u. and if u have the time i would recomend puttin the exhaust in urself. its one of the easiest mods. as long as u have jack mounts. (11 dollars each in a pawn shop and u can always sell emback)

320 if u pick up, if u want it shipped ide have to find out the shipping price. i think its like 20 bucks anywhere in U.S.
