best exhaust manifold

Posted

Anyone have any input on the exhaust manifold I should get? I'm undecided between the BD and ATS. While the BD has two ports driled and tapped and the ATS has one. The ATS also comes with a high temp black coating and won't look like crap after a few seasons. As far as quality between the two I have no idea. Currently the best price I have found shipped to my door is $425.00 total.

well, I just was looking at an htt and found it for 425 and it comes with all the gaskets....one thing I'm undecided about is the hight temp black coating. HTT doesn't come with that and ATS does....i mean I imagine the htt will look bad in a few years unless i paint it. Then again, will the paint all cook off of the ats anyhow?.....hard to say but its nice not having to buy gaskets with htt.

I have used factory cummins gaskets and like the way they have the embossed grooves. At one time i bought some fellpro from napa but didn't use them. They have some kind of coating on them but they are just flat.The pdi looks good.

Why doesnt anybody offer a high temp ceramic coating? Thats all anybody wants when it comes to headers. It would look good. And I would think it would keep more heat in the manifold.

Some do. My guess is cost. You can try jet hot coatings.

yes, who wants to pay 500 bucks, still have to port the thing and have it coated....not to mention after searching some of these forums I have learned that people are still having probs with the after market ones cracking like htt and ats.

Ones I feel sorry for are the stock truck owners getting sucked into the performance craze and then buying a high performance manifold for big money. Then get it installed and find out it didn't improve anything much... :duh:Personally I don't see a reason for any of the big manifold unless your pump some seriously big HP numbers.

Maybe I should just get my stock manifold coated? I talked to a guy at pri that said they only charge $75 for a set of headers. He also said it doesnt matter if it is new or used.

As far as cracking you have ask them all, how hot did it get ? Thats why they crack for the most part.Now about aftermarket exhaust. They help in a huge way,at least on mine it did. I look at it as every little helps. It is a matter of building all parts to work together so they help one onother. If your's is almost stock don't get one. Let me be clear about ALMOST stock, 275 rv injectors and a fass/air dog pump is still stock to me.If you want to see results from your stock manafold, gasket match it on both the turbo side and the exhaust side and smooth it out. All you meed is a drill and grinder bit. Then you can send it out to get a coating.

Yeah I know but my stock one is cracked bigtime and I don't necessarily think i should get another stock model. Now I'm looking at dps or ats. Some of these sites are advertising that the dps has a ceramic coating....I'm kind of doubting this.

Well, my truck is def stock....I haven't even beefed up the trans yet or added a tuner. I was curious if anyone has an ats on here and does the port for the probe come tapped and plugged or not. So, you think it's a good idea to port one of these aftermarket manifolds as well?

Yes, i just removed it 2 weeks ago. The ats that is. I ran it for almost 5 years. It has one port for egt. The reason i suggested gasket matching and cleaning it up a little is because it will help in a small way. You dont have to.

So, how long did that black coating hold up on the ats before it started lookn bad? Ever start rusting?

It is really hard to say when the change took place. I will post a picture up later on today for you.

I had wanted a equal length header for years. Had a buddy move on up to a 4t and sold me his used header.
