Just bought this 350 Dually 7.3 and have been noticing a vibration sound when starting out and then when I get to 60+ mph. I think I tracked it down to these bolts or what's left of them not doing their job. You can see the blow by. My question is what am I getting into in changing them? I would like to use stainless bolts to make future jobs go smother.
Not to nitpick but those look like up pipe bolts to me and the one side is going to be a bear to get out. How's the top end where they enter the baby's butt, are they leaking up there? If so you might want to install bellowed up pipes. I torch is going to be necessary to get the one side out and maybe even both sides. I'd use heat shields to protect the surrounding areas and cherry red heat it what it took to get mine out. Pulling the fender liners makes access a bit better too.
OK sorry for he lack of proper terminology as just started into this. Did a quick study and search and understand the importance. Why the difference in price. $69 to over $350 with the same number of parts. Obviously different manufactures but where do the differences lye?
There is just a yuuuuuggge price difference. Many people go with the cheap ones and have good luck but years ago Dorman had some quality issues and some (like me) will not use them (I've had other problems with Dorman and avoid them whenever possible). The IH pipes are premium quality and are the most expensive but they fit right in with no customizing necessary. Additionally, those for the E99 are different than they are for the 99.5 on up so you'll need to know what you have there.
As long as you switch to bellowed and install them properly, your leaks should stop for good. I went with Dorman and mine have been fine. However, I am not looking forward to ever having to remove them as they're kind of a one time use deal... the bolts, at least, are junk and hard to even get a wrench on once installed. I have not seen the IH ones in person but I imagine they are better quality... then again, even if you buy new ones every time you remove them... it would still take a while for the IH pipes to pay for themselves at $350/set. There is no need for stainless, at least where I live.
Those look good. Don't know why they wouldn't be legal in California but I wouldn't worry about it if I needed them. I have the International ones from Clay.
I did forget to list the year and it's a 02. I also have not looked to see how the up pipes attach to the turbo and surprised that a donut ring is used. Tried to find a pic in my Haynes manual and no luck. I was looking for XPD on ebay
and came across a slue of the kits from $40 to $350+. Kinda wonder the quality of the lesser priced kits and what makes them cheaper. If I can save a bunch here and it will go a long way for the budget. Here are a few of the listings.
One listings even had a heat wrap and although I think it's a great idea to keep temp lowered under the hood I would be concerned that it would send too much heat into the turbo and shorten it's life.
My thoughts...I just find it hard to believe that that collector (baby's butt) can be cheap to make and can't understand how a whole set can be that cheap and be any good. That places a road block that my mind just can't get past. Maybe I just need some professional counseling. I like to know that stainless steel is used in an application like this and ss costs more. I'm not sure why but keeping the heat in those pipes has more benefits than just keeping the heat down under the hood and Riffraff sells ceramic coated up pipes to assist with that, that's what I went with buy they are expensive. And the heat does not seem to be detrimental to the turbo.
All my "hot" exhaust parts are wrapped, the uppipes and the 3 exhaust pieces after the turbo underneath the crew cab. I believe i used 40' for the uppipes and another 110' for the exhaust. So far my turbo hasn't melted
Tried to find reviews with no luck. i did see some ceramic coated ones too for under $100. Don't have time to look as on my way to work. Suppose it would come down to the machining on the housings and the actual bend on the pipes. Are they rejections from the "better" manufactures? Who knows, was hoping to find someone who has ordered one and tried it.
I see some white where the exhaust manifold and the up pipe join. Did you use some kind of sealant when you mated the two together? I was thinking of using some exhaust paste there. Thinking of using a very thine amount to fill any imperfections or pits. Was not going to slather it on because of a concern that a piece could brake off and travel into the turbo. Wha do you think?
