RD Logics pipe

One of our staff members did a review of an RD Logics pipe for the T-Maxx.

View the link above for images of it installed on his truck. Hopefully it is the same pipe you are talking about.
 
Here is a link for the pipe in the picture in SkyMaxx's post, and for this picture: http://www.rdlogics.com/store/P_177.htm It is part #61510. I put one on my Maxx and it rips. It's very LOUD though.

Here's a pic of mine, with the P2 engine;

This pipe, or something like it, is a MUST if you install a bigger engine. However, for the stock 2.5 engine, I would look at the review that SkyMaxx references. The author put it on a 2.5 engine and gave the pipe a pretty good recommendation, plus you would have the pipe ready for a bigger engine. :devious:
 
I have the p2 on my t-maxx with the RD logics exhaust and I have split two headers already... RD logics has no explaination yet.
 
ammoguy, I have noticed some dents in my header pipe. This must be happening when I roll it over without a body on. Are you running with or without a body when this happens? Post a pic here, if you can, of a damaged piece. I would like to see what is happening. Any idea what is causing the pipe to break?
 
I have a roll cage and I have a show truck. All running has been on asfault with no roll overs. I attempted to attach a pic but the pic size was too large. I would have to e-mail it to you. The manifold was sent back to RD Logics two weeks ago.

All the header/weird damage I have incurred has been from an over flexible RPM rear shock tower.

It doesn't bend like tht with your hands, but a good hard landing, on the hweels or not, will flex that rear tower enough to beat the crap out of your header, and your fuel taks, and your nice shiny new cooling head.
 
ammoguy, you can reduce image size (maybe to 450x350) with just about any editor program and insert. Or, just email it to me at [email protected]

I am curious to see what's happening, as I have the same truck, engine and RD Logics pipe.

Thanks

EDIT: ammoguy sent me the pic, here it is:

lykan, I was thinking along the same lines, that it must be the shock tower

Hi, wanted to let everyone know that I spoke with RD Logics today and they realise the problem, and have developed a new header for those of us with customised T-maxx trucks. They have beefed up the header to deal with weight better. The release date is in Jun sometime...
I asked to be a part of their proto type testing team and it looks promissing !!!
Wow ... A company that listens and cares for their customers!!!
 
Also happened to a dynamite header with a .15 engine last month on my other Maxx... no impact/rollover .. How can this happen? Wonder if covering exhaust pipe to prime fuel contributted?

Take a look at my RD Logics header and you can see some pretty good dents. Now look at the engine and shock tower. They are much higher than the header and should be absorbing all impact in a roll. You can see the engine head is badly scratched. It must be the shock tower flexing into the pipe during a roll. Maybe this is what caused yours to break, ammoguy. I know you said you had no rolls, but maybe you don't have to roll for the shock tower to flex. Maybe just an impact.

Ammoguy,

Based on your pictures, I have one thought... chassis flex. How is the front of your pipe mounted to the chassis?

If you are having front to back flex in the chassis and the pipe is hard mounted to the front of the plate you could easily snap a very hot header in the manner shown.

Another possibility is over pressure. If the pipe and header are restrictive on the engine (as in too small for the engine in question), the exhaust pressure could cause such a fracture in, again, a very hot header.

Extreme heat tends to weaken things as does extremes of cold. Is your engine runnning at a good temperature? As in, not too hot.

Just some food for thought.
 
No, I use aluminum towers, and a thick chasis, no flex involved. RD Logics says they are aware of it and are about to release a beefed header in Jun. I think the weight of the exhaust muffler and the higher up exhaust port put pressure in the header at the header elbow causing a sress fracture. There is no impact evident with both headers that failed. The fractures failed from within, then exhaust gases probably helped the fracture to progress.
I currently use a DACE Chassis 3.5mm thick #DT1022N
