Here is my email and response from Greddy regarding their exhaust system for the IS-F from SEMA.....

My email to [email protected]:


I have been researching performance mods for the IS-F for some time and noticed that there is not too many products out for the IS-F yet. I was really interested in seeing if Greddy was going to come out with an exhaust system for the IS-F? I know you guys did a system on an IS-F for the SEMA show, any chance that will come out for production? Please let me know as I am anxiously waiting.

Response from Greddy:

Thank you for your interest in Greddy Products. At this time there are no plans in mass producing this exhaust system. However, you are not the only one who has expressed interest. If you can generate 20+ serious buyers, then we may be able to do a Group buy. The price is not set, however it may be in the amount of $2000 U.S. If you are interested and can locate 20+ serious buyers via forums/ car clubs, please call 949-588-8300 for more details. Also, you are not the only one whom I've given this information to, try going through some popular IS-F forums. There might be a group already being formed.

So what say we try to get a group of 20 guys here to have them produce the exhaust? hehe.... :D

so how do we get something going here, i want to hear it on a stock f without a supercharger also and maybe get some better angle shots of the muffler on the car.

You can shoot them an email to see if they have any other videos. You could also search youtube, maybe there is one on there without the SC. :cool:
So how many buyers so far are in for the Greddy's Exhaust? would the tips be the same or would they have to be removed??
I am in for a group buy on this exhaust.
Guys, i'm in for a group buy on Greddy exhaust
im ready for one too, the damn stock exhuast is tooo quiet for 420 poines.
is there anything happening with this gb?
Someone interested in a group buy should start/gather a list of names of people willing to purchase this exhaust, contact each person via PM to make sure they still want to purchase it, and then approach Greddy as a group ready to purchase so details can be worked out :cool:
whos gonna step up and get this gb going?
Why even start a GB for the Greddy system when the JOE Z true dual exhaust system is already available and affordable. let's poll how many ISF owners are running the JOE Z system and what their feedback is. I personally have been experiencing the system for about two weeks and am truly pleased!
I dont know if anyone has started gathering names but I would be down for this as long as it is under 2K.
The JOE Z system is way less than 2K. What is it about the Greddy that has such appeal? The JOE Z sounds great fits perfect weighs less and delivers dyno proven HP and TQ improvements of 22-24 and 15-18. Can you get more out of an after market exhaust system?
how much is the joez?
How is the drone on the joe-z??
how much is the joez?
MSRP = $1599

How is the drone on the joe-z??
No real drone to speak of. It has a great sound that is a clean, deep, throaty, almost muscle car kind of sound that is, imo, the way the car should have come from the factory :cool: There are videos in a thread on here of an F with the Joe Z installed :D
just installed the joe-z and love drone and no complaints whatsoever.
Great thx guys...Looks like my first mod is about to be ordered
Any of you guys with Joe Z setup live in Northern Cal - SF Bay area? I'd like to know where you got it installed, and would love to get together to hear it in person before I buy. Thanks.
i would too
