The other day I was looking around under the (driver's side) dash and noticed a unit with a mess of wires (harness) that looked a lot like the ECU that is in the engine bay. Don't even tell me that I could have tapped into this with my PNP harness instead of going through that damn firewall to the engine bay ECU...I will be so pissed!

 

Amazing install Nick Can't wait to see the dyno numbers.. I predict 263hp to the wheels once you dial her up.

 

Hey, Sean... what #'s do you think I can attain if I slap some headers on?

 

With headers you should be somewhere in the high 280's to low mid 290's maybe more. I'm at 266 with my setup now and I'm not tuned nor do I have a intake.

 

Heck, even 290WHP flat... would be awesome! That would be around 360-370HP at the crank. Combined that power with the 3.76 TT LSD and a 3K stall PI TC and your golden!!! lol. wait then you will need wider tires in the rear for more traction (which I don't have)...yet

 

I would say ~270whp, unless you have a full custom piping setup with an x-pipe. The OEM exhaust is pretty restrictive.

 

Besides headers...if I would ever want to entertain re-doing the entire exhaust, what oem components will I HAVE TO keep and what should I replace to still pass emissions? Do I replace down pipe, resinators, cats, mid-pipe etc.? I'm not really too knowledgable when it comes to the exhaust side of things...lol.

 

the cats are the only items exhaust wise you will need to keep to pass smog. everything else down there is just for flow.

 

Did you notice a difference when you installed (& tuned) your SAFC II as compared to when you just had your exhaust? Thanks...

 

Any updates on this thread? What kind of data came back from the dyno? Nice install by the way.
