3x3 to 3.5 out Y pipe users...
If you have LT's on your 346 except for SLP's with a 3x3-3.5 or 4' outlet Y pipe, please post up your dyno numbers. I am considering changing my 2.5x2.5-3 Y and would like to see what numbers could be had with a larger pipes.
TIA!
Joe.

I had one custom done with a 3x3 to 3 1/2 collector. We extended the 3-1/2" section about 14" and then taper back down to a 3" into the muffler. I never dynoed the difference, but I did pick up a tenth or two as compared to the original Grot Y with the Carsound cats.

Joe we dynoed before/after on my car switching from a stock FLP y-pipe to a custom 3" FLP y-pipe with 3.5" FM collector. This is when I had the tr224 and local ported stock CR heads.
