Might want to list what car it's on. I looked at your profile and saw it's an 11 GT. I don't have personal experience, but another forum I'm on this is a big thing. A lot of people have back pressure issues and have had to modify the hot side. A few ditched the Hellion and went with another company.

I think they have to have a bigger downpipe made. I don't know about the other wastegate. Most of what I've seen has been from reading when bored at work.
