well, I don't detect any extra or lost power, not that I had any before anyway. Stock, I had 28" tires and 4.30 gears. Now I have (temporary, thank God) 4.10s and 35s so I'm dealing with gutlessness no matter what. I do like knowing #6 isn't getting all that extra hot air in its face now.
For anyon who is less cheap than me, I'd recommend using 2" form the manifold to the Y, then 2.5" from there to the Cat and muffler. Then 2.5 or 3" for the tailpipe.
Thanks for reading.
