The TTi Kits do not come with an X Pipe, the cost for these components is less than $350. The intention of the kit is to mate up with the stock exhaust. There is nothing to show that the use of 2.5" exhaust hinders performance. There are a LOT of cars running around with X kits making more than 750 to the wheels with the standard setup Phil and I use.
Nick I think you misunderstood what I was trying to say. One kit comes with a 3 inch stainless steel exhaust going all the way to the catback and like you state TTi kits do not come with an X pipe.

What I meant was maybe TTi will eventually supply it's on X pipe combo...

As for the 750 to the wheels comment surrounding if 2.5" exhaust hinders performance that is an entirely different topic in itself. I have witnessed myself in the Supra world the performance gains from going from a 3 inch to a 4 inch exhaust. There is some gain in having a larger diameter pipe, but how much is the question.

If a 2.5 exhaust does not hinder performance but a full 3.0 exhaust allows for “better” performance couldn’t one make the conclusion that a 2.5 does in fact hinder performance when the option of a full 3.0 exhaust is available?

So with this said, it would be advantageous for TTi to produce a market specific full 3.0 exhaust to accompany their TT kit.



I have seen failure after failure in the 350Z arena using the single Turbonetics kits.

Are these the same product used in TTi’s kits?

I think I opened up the wrong soda. Let me make this a little clearer... The TTi X kit has put down 900 plus to the wheels with 2.5 inch exhaust. Now I personally do not have any backpressure reading, etc. I personally do not know the entire specs of the combo that put out 900rwhp plus, but I do know that my car is fully capable of making 900rwhp plus the way it sits. With that said.... If you put the APS and a TTi X car on the dyno with the exact same engine combo, but APS uses their exhaust and TTi use a customer supplied 2.5 inch exhaust will the cars put out similar #'s? That I dont have a clue about, but it should be close with all things being equal. I dont know the exact specs on the APS turbo's, but I think APS has reported 50lbs/min each. If that is true TTi's turbo's has the potential to make more power because it surpasses 50lbs/min by a good margin. Will the smaller diameter pipe hurt the TTi X car? I believe if you are going for MAX effort you will reach the limits of the turbo's b4 the exhaust.

Supra? 350Z?

We are talking about the TTiX Corvette TT kits.

Don't read into what I said... on the C5 kit there are already cars making in excess of 850 RWHP on the 2.5 downpipes. My car made 750 on just 14 psi through the stock Ti mufflers and the 2.5" exhaust.

No one has shown that there is a need for 3" or larger exhaust pipes on these kits. I am not saying there could not be potential gains from it. Exactly what I said was nothing has shown it to be a hinderance in performance.

If you put a 3.0 exhaust on your car and gained say another 50Bhp that would be the only way to determine if the exhaust is holding back any power.

I'm just learning here so please be gentle with me

I am quite sure that my factory Ti mufflers are holding back more than my 2.5" pipes. This is starting to sound like a debate about the "tiny" TTiX turbos ...

Not sure what your setup is, but 750 to the wheels is WAY more than you effectively put to the ground on any sort of DOT tire.

On 16+ psi the car is undriveable at any speed... as soon as the car gets into boost it starts to spin the tires.

At 12 psi and over 700 to the wheels, the kit is really in a nice place to be a fun street car. With drag radials the power is managable in third gear.

What does DOT tires have to do with it? You can drop a man with a .22 caliber handgun, but I prefer a .44 DE. Remember you must defeat your enemy with superior firepower..

Also, there is nothing wrong with my tiny turbo's...

You can have an 8" exhaust but if your stuffing it though a 2.5" catback whats the differance?

Second, take a look of the square area of the turbo mating component, and you will see how stupid this whole point is.

Actually Dan has a 408.

I am not sure how he can get it to hook with that kind of power.

Do these kits require you to swap out the C5 batwing oil pan for a LS2 or F-body variant?
