Yes, NA cars in general are much, much louder than turbocharged ones. LOL...a turbo or two in your exhaust-system is all the muffler you need.

i just dont want this thread getting spun around the axle because you believe that larger diameter exhaust tubing in no way attributes to the loss of low end torque...

Again with this.....

I can already get to about 470 WHp on my HR-TT with 2.25" exhaust no sweat. I've been in a VHR-TT with 3" pipes and I will tell you that it is loud (to me?), especially when it is started up cold. Just some things to think about if your Z is a daily driver.

@XwChriswX: IMO, do the 2.5" now and enjoy them. No rush to do forced induction until you are sure you are ready. If / when you decide to do so, you can easily get 500WHp out of them.

XwChriswX · 11-04-2009, 09:44 AM

To give more push to why I think I need the 3" is it's my goal to double the HP that I start out with, so if I roughly get ~300HP as a start, I'd like to see if I can break 600WHP. Thats my goal, however far fetched it may be, it's where I would be happy and can say I can move on to something else...

Also, the reason why I wouldn't care is I like volume I like mashing on the throttle and HEARING the engine come to life as you rock back into your seat... So I don't mind the up front cost of getting the 3" if in the end I don't have to trade it out later. I know F.I.'s Exhaust is awesome, but I dunno how many people would want a used one when they can get a brand new one for a great deal from Tony.

Breaking 600WHp will not be a problem with a TT. Caution though ... even the VHR-TT with the 3" pipes I was in made 600+WHp. GTM and the owner decided to clip the power output in the end for reliability sake.

If you like the sound of a loud exhaust, you will surely get it with the 3". Maybe it will motivate you to hurry with the TT if it is too loud N/A?

Here in CA, being less obvious has its advantages.

Something else to think about ... if you are planning on dropping 15 large for a TT, swapping out a 2.5" for a 3" should not even be on your mind. If it were me, I'd be curious to see if I can hit 600WHp with a 2.5". I bet it can be done.

Finally, Fast Intentions can also build their Z exhaust in 3" if you want. Give them a call.

Yeah, I don't wanna push it as far as feasible cause the funding just isn't there IF something were to go wrong. This will be my DD as well as my fun car, so I can't go all out, but I would like to set a goal and achieve it.

Yeah that's what I'm thinking, I'm not worried, as far as I know Z's get attention just for being so damm sexy lol So anymore attention isn't going to matter in the long run lol.

The TT won't be anytime soon, it will be after a deployment or something like that, parents winning the littery etc. etc. lol. It will take a while to get there...

I've just heard that it's better to have the GTM Exhaust if your going with the GTM TT kit since they make them to fit eachother and so forth...

They will both physically fit. It's a matter of personal preference so you'll have to do a little research and compare the two systems.

Ok, I'mma need someone with the GTM turbo kit and the F.I. Exhaust, and someone with the GTM turbo and GTM exhaust to come over and let me test them out side by side lol

J/k. Your absolutely right, I'm just waiting to see more Z's actually having the GTM TT kit and running in public...

kannibul · 11-04-2009, 04:40 PM

IMO, 600WHP isn't going to get you much because you won't be able to put it to the ground without some help...people are already mentioning wheel-hop with car stock, you add a whole lot of HP, and you end up with a situation where the car could end up being less controllable and less effective at making the power usable...and you'd never see that 600whp...short of for an instant before your car ends up losing traction...and worse...

It will be very interesting to see how a TT 370Z does on a track. Hopefully they provide some insight regarding how oil temperatures were affected, etc.
