| Duramax Full Bore Manifold
Duramax Balancing Big Bore Exhaust Manifold. Makes it easy for your engine to exhale.
Driver’s side full bore exhaust manifold for the 2001-2006 Duramax balances your engine power, reduces cylinder load, reduces exhaust temperature, exhaust backpressure and improves fuel economy.
The stock manifold:
• Only flows 80% of the passenger side manifold
• 3 cylinders only operate at 80% capacity & load others down
• No access to measure exhaust temperature
The BD manifold:
• Flow matches the passenger side manifold and balances the engines exhaust pressure.
• Maintains consistent exhaust pressure and temperature on both sides of the engine.
• Contains Exhaust temperature probe port.
BD uses a high silicon Ductile iron that prevents cracking from heat expansion and vibrations. Manifold gaskets required.
The BD Manifold compliments BD's SuperMax turbo charger kit for fully engineered exhaust flow design. |

| It was an easy install on my truck. My EGT probe does not fit in the hole very deep since I needed an adapter for my Autometer pyrometer. That was the only thing I didn't like. Otherwise, no issues.
FYI, I had my pyro in the passenger side manifold and the manifold cracked. A lot of manifolds crack after they are drilled because of the heating and cooling cycles the manifold goes through. I replaced that manifold and got a BD that won't crack on me. | |

| As far as I know BD is the only manufacture offering anything like this. BD is on the front end of diesel dovelopment and has their stuff together. I use their stuff shamelessly and thrash it at will. It holds up. For the price, you are hard pressed to beat most anything these guy come up with. I love em!

| Pat, is there an EGT probe you recommend for the BD manifold? This way I can get a gauge set ordered as I am planning on installing my manifold in a few days. I got my manifold from US Dieselparts.com and it was around $284.

| Is there really a significant difference in performane? or can you tell? does it have a spot to put a pyro?

| I know of no other manufacturer to offer a heavy duty manifold. I read a while back where the performance modules for diesels can/will crack the manifolds with the high temps. They have to have silicon impregnated iron. I read that Chevy did this but its manifold has a restriction (forgot which side) that impedes exhaust flow. The cat or turbo back exhaust upgrade would at best, only improve this flaw. The temp probe port is a good idea. I wish it had come out sooner when I was busting a knuckle drilling that port. | |

I just installed it on Friday along with a high idle. It does have a port already taped in the rear of the manifold and comes with two inserts; one for a thremocoupler and one that is just a cap if you don't have one.
I have pictures of the install but haven't been able to upload them to photobucket yet
