[AGR1755]

I have read a lot of posts pertaining to exhaust and the loss of low end torque and horse power (both duel and single) even with just a replacement of the factory muffler...so my question is this: since even the direct factory replacement method causes a loss in low end power, why not use a muffler with 2.5" in and 2.25" (as opposed to 2.5 in and 2.5 out) out and just get new piping from the muffler to the tip? or have a 2.5" in and 2.0" dual out (as opposed to 2.5 in and 2.25 dual out)?

Sorry if this has already been covered, but I have not been able to find any posts of anyone ever trying this particular setup and I apologize if its a stupid question...I just always thought that part of the problem with running aftermarket exhaust on our tundras was the pipe size and loss of backpressure. I just didn't know if decreasing the pipe size by a little more would help some of if not all the power loss?

Any comments or input is welcome and appreciated as always guys!
