Greddy Titanium exhaust
Does any one have this particular exhaust or have some insight on it? I'm compelled to the fact that it's constructed from titanium and the weight reduction benefits of it but I cannot get over the the dyno sheet Greddy produced on their site.
For reference, you can find their dyno test sheet here:

Why is there such a dip in power near 130 to 140 mph. It's a bit disconcerting considering the price of the exhaust. What would cause such a thing? Is it the design decision to use a H-crossover rather than a X-crossover? I need some additional justification to get this over something like a Joe-Z or a Borla cat back. Thanks for any information/advice.

The neat thing about the Greddy are the options you have with the exhaust. You can keep your factory tips or put the Greddy ones on. There also is a big weight savings of 35lbs over stock. Now is that going to be noticable in a 3600lb car.....doubt it. To be one of the few whom own one.....might be worth the entry fee!!
It sounds meaty!! How many times are you going to be travelling in the 130-140MPH range to notice the "dip" in HP???
It is definitely a premium exhaust!

I could always tell my chick to hit the gym and drop 35 lbs then I can save some cash on the exhasut JK she would KILL me if she just read that I agree with Kramer primarily with the "entrance fee" portion, pretty illusive setup, especially with a $3500 price tag. I didn't even put Greddy in my options on this car. I had a Greddy Ti setup on my last G35 and LOVED it, same thing , looked bad ***, pricey as heck, and everyone would say "sweet exhaust"
$3500 for an exhaust?! WTF...Joe-Z + Sikky headers cost only a little more than that and its like 50whp

I think alot of us would love to own the Greddy exhuast for our cars but with a price of $3,500 ?!?!?! The price is just insane ! It really isnt in the competitive market for exhausts for the IS-F.... But if you got the dough and wanna pay for some JDM goodness then by all means have at it I think im stuck between JoeZ and ISS QES, but thats just me GL with your choice bro !

Modify? You can barely do anything to it....all the M3s, all have crazy mods available.

I'm pretty sure its worth every penny. At the moment I'm still doing a lot of reading on what aftermarket parts to get for the ISF. I just got mine 4 weeks ago. I wouldn't mind spending that much for an exhaust down the road and if the craftsmanship is excellent and the weight savings is significant.
Off topic: I'm currently running the J's Racing FX-Pro 60RS Dual Titanium Exhaust for my S2000 that retails for $3,100 and I think it was worth every penny. I had a different aftermarket exhaust before that weighed 65lbs and the J's weights about 13lbs. The car feels a lot different with all the weight savings.

I tried to push weigh savings in the past as it is a big deal. Heck adding a passenger changes the whole personality of the car. The reason there are few parts is because it will cost money to develop and most companies will not do it unless they can make a profit. That is why I feel pretty lonely sometimes in this market
That being said though Ti is expensive and getting more expensive all the time. I looked at making a full system but it would end up in the same price point. I would like to see more like 60lbs savings though since I saved over 20lbs just by moving to twin ti canisters on the rear section. But the dyno numbers will never be impressive enough to justify the price, the weight has to be considered. If you are going to spend the money do it because you want the thing. Its hard to justify if you just want to look at a dyno chart.
