Ok guys I have a couple friends with cummins and they all started getting manifolds so started to get me thinking. What ones is best? Then we started talking and all of them are getting steed speed so I looked into it and found this..


Anyone have any word or clue on this. When if ever? Worth the money? The others ones for the cummins and powerstroke look like really nice products. What do u guys think?

Do you have an after market turbo? What's your reasoning for exhaust manifolds at this point?

BD is a drivers side to overcome the poor factory design, many people opt to go with the LML instead.

Typically people don't install aftermarket manifolds until after they've done a turbo and honestly they aren't that popular of an upgrade.

Ok so factory with just the lml driver side is a good set up.

Yes, I wouldn't personally upgrade to PPE until you were further down the road. I've seen lots of claims that the only benefit was EGT, but IDK. Lots of very high HP trucks are running on stock manifolds and up pipes.

for the price they are not worth it..i have ATS manis/uppipes and regret wasting the coin.
i would go with profabs if i could do it again, the ATS's have a pretty crappy design IMO..

Not trying to jack the thread but when I have my twins going would it be worth it or just stick to stock?

Unless you are squeezing out every 10th for a race application I wouldn't worry about it. With twins you can look at the Pro Fab up pipes though, he makes one that is designed specifically for twins since you don't have to fight with the stock down pipe.

Not saying manifolds aren't good, but if you're not racing I don't think I'd worry about it until everything else was already done. I would get the BD or LML though for the driver side.

I run PROFAB. The reason I bought them is because I had the moter stripped down because of failed headgaskets. Maybe a waste of money but the flow is so much better and its my money.
