Does anybody know where i can buy downtubes for my 1991 Thunderbird Sport 5.0 HO? The current downtubes look like a major restriction..Thanks.. :)

Your best bet is just to find a local exhaust shop and have them bend some up for you.

if you have stock manifolds or mn12 shorty headers then the supercoupe performance v-6 2.25 downtubes will mate rite up with no fab work

the whole front section of my exhaust is for sale.from the shorty header all the way back and will connect to the stock rear section.

Long tubes are definitely the way to go If you plan on some high horsepower in the future..For what I'm doing I'll stick with my shorties..I may be interested in just the downtubes..I'll let you know..
