Hello All..
After 3 months waiting for mods. I changed my heads and downpipes.
Before I had Patriot Stage 3 72cc and 2.5" downpipes with Borla exhaust. Now I have AFR 230 72cc big bore and 3" downpipes with 3" Straight Bullet Dynamax exhaust with 3" X pipe and dump.
The car hit the rollers today at HPSales Pompano Beach, FL on Mustang Dyno and this is the results:
Before Mods:
813rwhp and 863rwtq 20.3psi
534rwhp and 657rwtq 8.2psi
After Mods:
1009rwhp and 943rwtq 20.2psi
619rwhp and 730rwtq 8.3psi
Gained
196rwhp with 20psi
85rwhp with 8psi
These mods make the turbos spin so quick now.
Before and After with 20psi
The tires spin a lot on dyno
Before with 8psi
Now with same 8psi

Thanks guys.
The setup is a 408 iron block, AFR 230 heads, custom Intake manifold, HP Turbo Kit with Precision 57mm .67 A/R 3" downpipes, 3" X-Pipe, 3" Dynamax Straight Bullet Muffler. I also added an oversized radiator with oil cooler that helps a lot. My Patriot Heads Stage 3 didn't hold power over 800rwhp, I replaced my head gasket twice with LS9 and it's still pushing water. So I decided to fix it once and for all. AFR is the way to go. I am very pleased with it.
Do you have pics of the 3" down pipes? I don't recall there being any room for that. Who made the DPs?
I wasnt' there when they make it, but I managed to take couple pic underneat of the car. Fit's very tight. Mad's Hatter Mufflers in Pompano Beach, FL. They need the car on site so it can be done correct.
