Pretty impressed with these numbers on stock headers/cats

Cory Gillmore

I’ve got an 09 370 with AAM catback exhaust. Z1 CF CAI. Z1 coil packs and the Z1 silicone hose kit, Z1 ported intake plenum. Just got back today from Z1 in Georgia where they tuned it.

Definitely higher than I was expecting with the mods installed.

Pics of the hose kit, intakes and the undershrowd.

Some additional info on the car:
Z1 installed the CF CAI, ported plenum, hose kit, undershrowd and a new front lip just this past week. Then tuned the car.

Before that I had the AAM catback and a K&N Typhoon short RAM intake (AKA a hot-air intake lol).
I ran the K&N intake and an AAM muffler delete for about 3 years before I added the rest of the AAM exhaust, making it a catback system. First time the car had ever been tuned was just yesterday.

I installed the Z1 brake upgrade kit myself this past spring. Which consisted of drilled/slotted rotors, pads, Motul 600 fluid and SS lines.

I just installed new spark plugs and the Z1 high energy coil packs myself a couple months ago. Which solved my P0300 issues, rough idle issues and made a notable difference in how the car ran. Really seemed to wake it up.

Car has 107,000 miles on the clock.

After a few Dyno pulls the tech came in and asked me if I'd had my stock cats hollowed out lol. I told him no. They seemed very much impressed with these numbers on stock cats and headers.

The day I dropped the car off there was a dude there with a 2015 with full exhaust and test pipes and his car made 318whp on the same Dyno.

Yeah brother it certainly surprised the hell out of me. One thing I can say about this car is it has been babied its whole life. It was owned by a woman in Indiana before me and I bought it at 70,000 miles.

I believe the hardest day its ever had was the day it spent at Z1 getting tuned on the Dyno and then in the parking lot after where the tuner showed me how to use the launch control. I had never launched it like that before. Never even done a burnout before.

Before that I think I hit the rev limiter in this car maybe twice.

Finally got a video uploaded to YouTube lol. I wanted to just upload it here but that doesn’t seem to be possible. And I didn’t want to use my normal YouTube account because it’s a bit of a troll account and I don’t want it linked to my actual name in any way. So I made another YouTube account.
