Whoaaaaa…$2500 for a ceramic Flowmaster exhaust? Seriously? What kind of car do you drive?
You should be looking at roughly $500 for a Flowmaster cat-back for your mustang but you don’t have to stick with Flowmaster just because you’ve heard of them. I’m not a Mustang guy myself, but I’ve heard a lot of good things about the Bassani Quiet Thunder. Supposed to be the best sounding and highest performing Mustang exhaust under $1,000.
