What diamter is the collector on the slp y-pipe?
of the I-pipe. The I-pipe looks to be 3.5"
(whether or not this is SS-specific I don't
know) at its natural diameter but the front
is swaged down. I would make the SLP
collector to be 3.25". It looks well formed,
it's a formed tube that's relatively smooth.
This is all eyeball to tape measure, I can't
find my calipers.
Sounds like its a nice piece. Do you think its worth some power over the stock y collector?
