I based it off the Flowmaster application guide:
2005 WK 5.7L 50-series PN 9530560
3" offset in / 3" center out

..... figured they didn't change the exhaust system in following years.

Also all ram truck 5.7L applications in our model years have 3" I/O specs.

Guess there's nothing left to do but get out the tape measure! Lol

I am pretty sure your right because I measured it before and I don't think it was 2.5. However, Ahmed on JC.com had the 2.5" installed lol
