Here are the three bolt flanges that mate to the stock manifolds.
They use the stock metal o-ring seal on the driver's side and the passenger side.
These are made from quality 3/8" stainless steel.
These flanges are ideal for custom exhaust or turbo kits using stock manifolds.
If you just performed an LS swap and using the stock manifolds, and plan on running custom exhaust, you will need these.
Exhaust shops will not have this flange.
Drivers Side: $26
Passenger Side: $26
