Default dna gt45 or on3 76mm?
Tried searching and found nothing. Which one is capable of more HP on a stock bottom 5.3?

Given the choice, I prefer the the GT45. The GT45 will have less backpressure over the mismatched On3 76 with the small 65mm turbine vs the 77mm found on the GT45.

Gt45 as well.i currently have the on3 76 makes great power but rpm range is limited due to the turbine on my ls6.
