Can i get an opinion on this?

eBay Motors: MBRP POWER TUBE FOR ALL 4" DIESEL EXHAUST SYSTEMS (item 270091632475 end time Apr-20-07 09:08:29 PDT)

I wonder where in the exhaust system that is supposed to be placed.

IF the numbers are truly accurate, then it sounds like a pretty good deal.
Here's MBRP's install link.
I would probably contact ITP or DPPI and see what Dennis and Craig say about the item. Perhaps they could even get a better price on it??

I would think that it would go in place of a muffler. Post Cat.?

I didnt click the link but I bet its a copy of the aeroturbine. The Aeroturbine goes as far forward as you can get it to the turbo and on my truck it dropped EGT's about 75 degrees.

i think this might help explain it. MBRP Has New 5-inch Diesel Truck Exhaust Systems - Google Video the actual part you wanna watch is at about the 3:03 mark

The best place to put the Power Tube is in the downpipe. You have to cut a section of downpipe out and put the tube in. I have one in my truck.
MBRP told me installing it in the downpipe will give you the best performance, but it can be installed just after the downpipe as well.

 

[Sleeper Diesel]

did it make a difference in the downpipe.

MBRP Power Tube For all diesel trucks - Part # (1001)

Your diesel truck was designed at the factory to "push" the exhaust through the stock exhaust system. Once the maximum volume is reached, there isn't any room left for additional flow. We always recommend installing a 4.00" exhaust system and a cold air intake to make room for increased exhaust flow. This works extremely well for increasing power, torque, fuel economy and lowering EGT's. Until now, there hasn't been much more that can be done for increasing exhaust flow.

The MBRP Power Tube is engineered to accelerate exhaust flow when installed into a 4" diesel exhaust system. The Power Tube works on the venturi principle to speed up the exhaust flow. Exhaust flow in the center is always travelling faster than the exhaust flow along the outside walls of the exhaust tubing. The exhaust travelling along the walls off the tubing is slower and is commonly know as boundary layer flow. The Power Tube decreases boundary layer flow through the holes placed around the internal venturi. Decreasing the boundary layer flow will reduce flow friction and increase exhaust speed and velocity.

By increasing the exhaust flow, the engine works more efficiently in the lower and mid RPM range. The Power Tube not only creates additional torque, but tests show it also can help improve fuel economy for your diesel. Each Power Tube is full CNC built to tight tolerances; the tubing shell is stainless steel and comes complete with 4" clamps. All of the parts that you need for installation are included in the kit. Please note the Power Tube will fit and work with any 4" exhaust system on the market today. The overall length of the Power Tube is 11".
