-Royalmuffler.com, exhaust, not sure on $, sounded o.k,, no power #'s
-SRT true duel exhaust, titanmotersports.com (orlando,FL), $1199, 10-12 RWH claimed
-Joe Z intake, $140, pipe only, no filter(uses stock), 5+ RWH claimed, VIP auto salon

Good research suprajones. There are some third party dyno numbers from other members you should check out on CL if you haven't already I would do your research on the SRT and single stage intake products

There hasn't been much released for the F yet. You can blame the economic times we live in and plus the IS-F is a new car.
The SRT intake also comes with the ECU mod that adjusts air to fuel ratio. Anyone knows how the ECU mod is installed? is it just plug and play and where the ports are? also, is the JOE Z intake similar to the SRT one only without the ECU mod?? Im confused as i'm hearing good things about JOE Z and less good things about SRT

The Joe Z intake is not similar to the SRT. The SRT intake removes the entire stock air intake box (filter, etc.) as well as the stock tube. This results in the F having a single stage intake instead of the stock dual stage intake. The Joe Z is an intake tube with no ECU changes that keeps the stock dual intake box and only replaces the muffled stock tube.
Here is a link to SRT's website to help you:

Thanks Big Mike... This therefore means that if I was to do the DIY intake mod which is on another thread, and install a Joe Z intake, it would do the same job excpet for the ECU mod the SRT intake has"?
If you do the DIY stock intake mod and add the Joe Z pipe, it is still not the same as adding the SRT intake.Thanks Big Mike...

The SRT intake completely removes the tube and stock intake box. You have to do the ECU changes as well to make the SRT intake works well with the engine as the F is designed for a dual stage and not a single stage intake setup. If you look at the pictures in the above link to the SRT website and then go out and look at the stock intake in your F, there is quite a difference. The SRT has a long single tube connected to an open head filter surrounded by a heat shield. The stock intake has a shorter tube connected to a box that has an air flap that opens for the second intake.
The DIY intake mod simply unplugs an air hose and forces the car to open the secondary intake earlier in the RPM band then it is supposed to (2300 or so compared with 3600). If you had the Joe Z pipe and do the DIY intake mod, you still have a dual stage intake in the F, your just forcing it to kick in earlier compared with a complete single stage intake with an open filter.
i think the dual stage intake is one of the characteristics of the F, might just go for the Joe Z plus DIY... not sure yet though! is the SRT mod reversible? thanks for the info
Yes the SRT mod is reversible
Sounds like a plan btw guys im still waiting to receive my car!! it should arrive in about 1 week or 2 hopefully and I can't wait!
btw guys im still waiting to receive my car!! it should arrive in about 1 week or 2 hopefully and I can't wait!I know for a fact that AEM has an intake in development. From what I hear they estimate a 20-30 hp gain. Knowing how thorough they are in their development and their usual hp gains, I think they will do it. Stay tuned. They should release it within the next 4-6 weeks...
Now is that a gain at the crank or RWHP where it counts?
Wow, that much horsepower just from an intake?
I will reserve my judgment until I see photos and dyno sheets

Just heard Borla is going to be releasing two versions of an exhaust for the IS-F within the next two weeks. Similar to what they offer on the IS350.
Gain is measured at the wheels. AEM posts their dyno sheets on the web when they release a kit for sale.
I know a couple of the engineers at AEM. The company is very hard core about being honest on their published stats. And, they actually publish an average of three pulls, instead of the best one like some companies do.

That's an amazing gain! Ya think it will be similar to the SRT intake setup?
BTW... does anyone ever get a drone from their JoeZ exhaust when just cruising below 2000 rpms..
AEM has gotten these types of gains in the past. Check out what they did with the original S2000....10+% gain in hp and torques! Don't forget that AEM are the real pros at intake design. Plus they have one hell of an electronics crew to back it up too.
I think it will be similar. However, I am going to put my money on AEM to do the best job and get the most out of the design.
