I am going to have to disagree w/ that: when I had a straight-pipe on my
truck( no muffler, but had the cat on) I didn't seem to lose any torque,
but when I put my Flowtech on I got a very noticable increase over
stock. This tells me that even on a v8 tha cat alone does not allow
enough restriction (backpressure) much less on a v6 with the same pipe
diameter (2.5").
