Just curious how many of you are supercharged and still running the stock headers? I'm at that point where I've got full catless exhaust except stock manifolds, and power delivery still feels really good on the stock headers. From two days of researching, it sounds like when supercharged, scavenging is irreverent and it's more about cfm at that point, which our stock headers do alright. I'm only going for 600whp-675whp, and I understand eventually you need to go headers, but even the roush phase 3 is on stock headers. Just more curious what you guys are running?
