I got this off the Magnaflow site. This is the Magnaflow 16612 that MT sells. He states that it does not lose torque at any rpm. Does this dyno prove you still have low end torque? Why does this dyno start at 3000 rpm? I want to see the results from idle (700 rpm) to 4000 rpm. I would think that would be more representing of the low end torque.
Does anyone have this Magnaflow set up...and do you lose low end torque?

 

Magnaflow I've heard you DONT lose low end torque but I know with my flowmaster I lost some low end torque...

 

thats weird with my flowmaster i gained low end torque, i reach peak TRQ at 2747 rpm and it steadily drops from there
