In part this is true. loss of torque directly relates to the amount of backpressure there is when talking about exhaust. however when comparing Y pipe to True Duals the diameter of the pipe will be the deciding factor. if you go with bigger pipe then what is needed in any application then torque will be lost. however, in general, the better the exhaust flows the more HP you will gain.

Ok so how do you know what size piping will be needed?

depends on HP. If you're limited on space then obviously smaller is better. 2.5 inches is good for most applications under 400 HP. 3" is needed above for cars. Smaller pipes is good for trucks as stated above because of the torque loss resulting from too little back-pressure

Basically from a performance aspect, you can't go wrong with TD's. Read deeper into this thread, scavenging>backpressure

I'll edit this post and add pics one I finish painting the tailpipes flat black.
This exhaust is 3" Mandrel bent, over the axle with X-pipe and Hooker Aerochamber mufflers.
Excellent ground clearance and sound.
Driver's side muffler is in the stock location, passenger side is between TTop and Spare tire wells. (2" x 3" BFH work required)
Materials:
- 4 Dynomax/Hooker 3" Mandrel U bends (I have 4 left over in my for sale thread)
- 1 Jegs Universal 3" X-pipe kit
- 2 Hooker Aerochamber 3" in/out Mufflers

Looks great! Not diggin the tail pipe covers though....just my opinion though. That is going to sound awesome!
Got any sound clips yet? Looks good man.
I'll edit this post and add pics one I finish painting the tailpipes flat black.
Will also add a vid, it's been too windy this week to get a decent one.
