Need source for aftermarket exhaust manifold

Recommended Posts


Would someone please direct me to a supplier other than a Mack dealer for the following part numbers.

21010850. Exhaust manifold

21010782. Exhaust manifold

20901575. Stud

370SB24A. Kit?

I have a worn out exhaust manifold on my ‘05 CV-713. 

Trying to fix it with all new parts, but the dealer’s prices are outrageous.


Thanks in advance

You need to go to PAI industries. They supply aftermarket for Mack. You can phone order from any PAI dealership.

If I can make a suggestion against stock (click on attached thread for other parts including exhaust manifold on page 5). 



You need these for your truck.......

Ends are 21090679 (104GC5164M-old number) $284.06, of which you need 2. 

Center is a 21090730, $203.99 (Both 104GC5165M3 (high temp center) and 104GC5165M (regular application) supersede to same number.... 21090730).

Not to derail this thread, but would a guy gain anything by just changing the manifold only?
