exhaust manifold

[mackthehack]

I saw on ebay a bd exhaust manifold for the drivers side. What other mods do you need to run one of these? Are these manifolds even worth paying for? Is there any performance difference between ss or aluminized exhaust

You don't have to do any other mods to run the BD exhaust manifold. It is just a little more free flowing. If you plan on adding an EGT guage, it already is drilled and tapped for the probe. As far as the exhaust, there is no difference except appearance. If you live in an area that uses salt on the road or deal with salt water, you would be better off getting SS. Otherwise, aluminized will work out just fine.

thanks for the info.

ON your truck make sure you have plenty of time to put it on! After the fact they told me to soak the bolts a couple days before you do it. It'll take some patience. Goodluck to ya. I put mine on on Monday.

Just installed the BD manifold on my truck last weekend, only took about 2 hours. My truck only has 5,500 miles, so all the bolts came out easy. It wouldn't be a bad idea to soak the bolts, especially if your truck has some miles on it. BD doesn't mention it, but if you remove the pipe from the turbo to the intercooler, gives you alot more room to work. I will say I did notice a increase of power after replacing the stock manifold and it made installing the EGT probe very easy.

thanks for the tips, my truck has about 4650 on it, but will soak the bolts to be safe.

BD says an increase in airflow yielding an increase in turbo spoolup and lower EGTs.

[mackthehack]

Thats what I like to see better airflow, lower egt's faster spool up, thanks.

Where in Norcal are ya?

Rancho Cordova, I haven't made it out to check out your facility.
