Application Note 2: INLET X 5" OUTLET)

it's flow rating stinks compared to the 4" IN X 4" OUT 51" Donaldson, but it's decibal rating is almost double ... so for giggles I was just wondering ...

Additionally it would give the user 5" look since it's got the 5" out tip (the original reason I was looking at it ... 4" IN, 5" OUT)

 

i just wanted to know if 5 inch made a differents. it looks like ut does not so there is no need. am saving for my tranny any ways.
