Thanks for the update. I had a feeling it was a resonator issue. The catback I have has resonated mid pipes so that would explain why mine sounds similar.
I have the same noise. Almost the same setup except no ghost cam and I'm using a Stainless Works catback with catless LTH. I hear mine primarily on the driver side but have no clue what's causing it and my lift is down so I haven't been able to get back under it and check.
The horsepower is doable but your still going to be below 600lb/ft. More so in the 580-590lb/ft range from most the custom tuned Roush cars including mine that was tuned by DRP.
I doubt Roush is going to change the tune. I emailed them about a month ago about seeing if they were going to do tune updates/change kinda like Whipple was doing and they were pretty adamant about what you see is what you get. Now could other circumstances come up to make them change sure but...
They'll just make another 300k+ variant and keep chasing Corvettes. New platform is also funny as they can't handle the recalls they have now much less something new.
Just backing up what Sin said. It's almost 48k for a base bare bones GT now. Overpriced IMHO. Especially now that I'm seeing some of my local dealers taking 6k off MSRP.
I think it's the headlights that actually set people off. 2 things I've heard since the s650 came out was 1. The front end looks like an Accord. 2 it looks too much like the 6th gen Camaro.
