Anyone have any thoughts on these? are they worth the money to upgrade? are they reliable? thanks

Aftermarket up pipes and headers opinions.
- Thread starter bigbird
- Start date
i am running rdl's feed pipes and i am happy with them , no problems so far and seem to help part throttle response but spool up is were they realy shine far better spool up charactoristics than stock . cant speak for the headers .
I think the jury is still out.
I would love for someone who is not involved in the mfr of them to do some unbiased dyno and drive pressure testing.
I tried last year, but things didn't work out.
I'm running the PPE Riser Pipes, and they are excellent quality, and certainly flow well from what I saw on the dyno. Hopefully I get time to test them specifically.

The ones that are currently available are not worth it in anyway. There are reasons why "fast" trucks (10's,11's) don't run what is readily available from Rick. They are made from 304SS when they should be made from 321SS. I have seen his up pipes in person and lets just say they are not something I would run on my truck. Braided mesh bellow joints are the only way to go unless your looking to spend a lot more on good slip joint's.
My advice is to talk to people that are running them.
And also Rick by my statement i'm not trying to anything against you or your craftsmanship. I do agree with you to ask peoples opinions
Here's what I do know. The factory pipes can and do deform or fail at high EGT's seen drag racing or sled pulling. That reason alone is enough to run aftermarket parts.
Prior to aftermarket tubes, I ran OEM riser pipes that SoCalDiesel had ceramic coated inside, and thermal coated outside. They held up very well.
But the factory risers are engineered for 3000rpm, so at least in theory, if you spin lots faster, you are going to need bigger pipes to free up some power when they start to choke.

Merchant wants to build a set of up pipes for my truck and for Darius's. He wants us to get dyno numbers beforehand, and then we'll go back and dyno again after the install. I guess we'll see if this goes through or not.....
From all I gathered from the LB7 turbo thread, we dont want to run pipes larger than the flange openings, correct?

When you do the dyno, run the truck up to 4000 if you can. I gots a feelin' that's where you're going to see the difference.
As far as the size goes, if you are going to run headers in the future, you might want to go 2.125" all the way to the T4 base. This is about 50% larger than stock, and the same area as a T4 charger inlet.

i have no ties to rick i bought them from txcristopher, so my description is from my opinion on the part only , i would ask people who have actually had the product and feel the results daily to get a good ideas on the gains not just personal opinions , i have never claimed a power gain though i can feel it mainly at part throttle but have continued to praise them for better spooling of the turbo , and i cant vouch for the longevity but so far so good have had my egt gauge pegged plenty of times but will know more after next season of racing , and towing the 5th wheel all summer .
Couple of years, eh?
Yeah, mapped the different mounts cross-sectional area, and I'm going by memory.
I built my own and had somebody else tig 'em together. I have no hard data either, just alot of common sense. Some things are just a no brainer.
IMO- can't do much worse than the stockers in performance terms. They are less than 1 3/4" ID bent around obstacles, ovaled in some places, not in others, short 90*'s.
take the stockers off and hold them in your hand next to (2) small 1 3/4" 90's and a straight section of pipe with a bellow. The stockers are anemic.

That is the biggest advantage in bigger up pipes and or headers are the EGT reduction. If your a 10 second truck and at the traps your hitting 1800 EGT's and then they drop to 1600 or 1650 that would help your engine and turbo live a lot longer
I tested them with back to back 1/4 mile runs. I saw no gain with the twins at 3600rpm's and 50 #'s of boost.
They then split after a short time(less than 2 weeks). I've not had problems with the stockers before or since. This was in the spring/summer of 08, not sure if material or craftmanship has changed since.
