hahahahaha it would still hook up. Like when you hook up just a cat-back that's 3" to the stock cat.

Ok, I tested my setup today. "Stock catback, UR HFC and Megan downpipe..."
The result was: I lost 20~ 25 WHP from my previous Helix catback set up.
Guys, it looks like the stock catback is the big bottleneck. Change your catbacks before you do anything else.
