How much hp with long tubes

[JOJOEGT]

I was thinking of doing long tube headers with cats on my 06 gt with kenne bell stage 2 blower.I have a cut in pro chamber now with ford racing mufflers and it made 446hp. What kind of gain would I get with long tubes.

I gained 30rwhp with Lts and O/R H pipe! How much boost you running?

6 hp

I'm running 10 pounds of boost. I don't want to hurt the motor yet.

20-30rwhp with an offroad midpipe.

Sounds reasonable.
I made 320rwhp with cai/tb, longtubes, udp and 93 octane tune.

That's what my car made with those mods.
