congrats, how much is that carbon exhaust, im really interested in it, could someone pm me to let me know? thanks

Thanks! To answer your question: my 370Z is currently at stock height.

PM Tony and I'm sure he'll be more than happy to provide pricing.. F.I. Inc

LET THERE BE VIDS!!!



hurry!

yes ^^

That looks great! Thanks for taking the time to write everything up for us and for taking so many great pictures. This system is the TITS!


Oh and that sandwich looks so good. I want one now.

Thanks for taking the time to post this phelan. Definitely adds to the anticipation even more now.

To Tony stop posting on thread and get back to work hehehe (thanks again though mate).

Now to read the review properly.

I got you covered, here is the link to my sale thread:

Call me when you are ready...

Thanks, Tony

Posted dyno results. Tony, PM.

Recieved.

Phelan,

Your Air Fuel Ratio is NOT too rich. It is on the leaner side. The higher the number the leaner the A/F. The lower the number, the richer the A/F.

Optimum A/F for a naturally aspirated car is: 12.6:1-13.0:1

You are right in the optimum area.

Now, this makes sense that you car has leaned out. When you relieve back pressure like you have you lean a car out. Now, your mass air meter is designed to compensate for modifications. It does but only to an extent. I am looking at your dyno charts and I can tell you that the car leaned out. They are higher than the previous numbers. Also one thing to keep in mind, A/F numbers will be a different number the further back the reading is taken. The optimum point to take an A/f ratio reading on a dyno is before the catalytic converters. So to recap, I know that a set of aftermarket cats and cat back exhaust system such as ours WILL NOT lean a car out to the point of DANGER. However, it doesn't hurt to get a car tuned after the fact.

The popping noise you hear sometimes on deceleration is the freed up back pressure due to the free flowing exhaust.

One more thing to add, even though you are on a dynapak you are still hooked up to the axles, that is still considered a rear wheel or (at the tires reading)! To record flywheel power you have to dyno an engine on an engine dyno out of the car.

Call me if you need anything...

Thanks, Tony

Yeah, I knew the A/F basics, but I thought 14.something was the optimum ratio ><' oops

Thanks Tony!

This is one of the things I really like about the exhaust system. The "popping" sounds awesome to me.

I love the popping sound. My bike does it too when I down shift for a hard decel. It's funny too because apparently you see flames out of my tail pipe on occasion. :D

Yup, it's just a word of warning to those who aren't prepared. I still freak out every so often at the really loud one, but I'm mostly used to it now, and it's quite nice :tup:

Gratz on the install, Phelan! and great pics!

I get the pop (more like a gurgle) too. (FI CBE w/stock cats). This happens on deceleration between shifts most noticebly 1st-2nd, 2nd-3rd gears on my car. No idea what it sounds like outside the cabin.

I was concerned at first but listened to a video I had of the my stock exhaust and had it then too, although at a lower volume. Just more noticeable on the free flowing exhaust as Tony mentioned. I got used to it. :tup:
