Haha who knows! My iat’s We’re solid and my car runs like a raped ape! Same with my car dude, I’ve found that with stock tires, I literally can’t hammer it with everything off, until 100! Love it!

Any rubbing sounds from the 2 " pipes? I saw a thread that someone is going down to the 1 7/8" cause of rubbing. Also just wanted to verify you only did the lower pulley?

^ that was me. I think I'm the only one so far on the Zl1. There was a guy on YouTube who had the 2" and he didn't have issues. (I hit him up to ask). And it does clear btw the headers. I can go out now and see clearance, but for some reason, under load, it's hitting them.

On my car, I don't think it's the headers. I think I might have some flex in the steering shaft, but it's weird cus it only hits the header turning to the right, not to the left.

Those are good number btw. I'm hoping to hit the 700 mark this coming up week.

Not sure. You would think not with only 500 miles on it. We are just going to go 1 7/8 and call it a day. I don't care if I lose a few HP. Would rather have clearance peace of mind.

You know what, I'm an idiot. I have my car here. I'll go out and take some pics. Don't want to thread jack this guys thread so I'll put it on my thread. (Uploaded pics on my thread).

I have 2" American racing headers and no cats. ZERO rubbing, ZERO issues. and my car makes 654/664 to the wheels through the A10 with LPE 18% lower, Roto Fab and Headers.

Good #'s man. I'm 649/610. Basically same mods, but I have the upper pulley done and Corsa exhaust.

I will say we've been doing hot runs tho since we aren't focused on final #'s as we are still building. But, this week the game changes. New mods coming, temps in the 50's. I know I'm going to see 680 at the wheels. Maybe 700's. I might have to photoshop the Dyno sheet for that to happen tho.

Those numbers are incredible for the bolt-ons you added, who tuned it for you?

Did you do your headers with a cat delete to the suitcase muffler?

Regardless of who tuned it, that's some great work. Lot of bang for the buck.

Yes headers, cat delete all the way back to the stock muffler. Josh Isaacs at Lashway motorsports tuned it. yes I agree huge performance for the money! the dyno number are not a big deal, ill be impressed if it puts down good times at the track.

Yeah, my ARH 2" headers do not contact anything...?

This was Kooks, not ARH. Looks like ARH leaves enough room for a picnic.
