Just listened to your new vid plus the older ones where you had it positioned behind the wheel, as well as the before and after the Corsa tip.
So, you got rid of the resonator and third cat and only have the muffler. You say no drone, or minimal drone while cruising on the highway around 70-80mph eh? This exhaust sounds really good, sounds sick at idle, especially when you put it in D lol these trucks have a good lope to em!!
What kind of sound difference did you notice between the single exit and twin exit tip?
I'm getting tired of driving around stock and was really hoping to do a Corsa, but I'm now a new home owner and reality is I can easily justify $300 on an exhaust, not $1100 at this time. I don't want to drive stock for another 2 years or so. I think what I'd do is buy this muffler, take it to a shop and have them remove the factory system and then just fab up a quick cat back out the one side.
Edit: just listened to your highway pull vid.... man I miss that sound!!!!
