I want to TT my Z eventually... However the funding will take a while to aquire... so do I:

A. Go ahead and enjoy the F.I. 2.5" Exhaust for now, until I can get the GTM TT/3" Exhaust?

B. Go ahead and get the GTM 3" Exhaust so it's something I don't have to buy later?

Buy the FI exhaust and enjoy it now, then sell it when you get the twin turbo.

Sure. Or just buy the 3" exhaust now and enjoy that, while not having to deal with the hassle of buying/selling more parts in the future.

Persoanlly, If I was 110% sure I was doing a TT setup, I wouldn't waste the time going with a NA exhaust just to sell it, lose some money on the item and then purchase a new exhaust. I'd either stay stock and do it all at once or I'd get the 3" now and just eat the loss until the TT goes in.

Eat what loss?

3" pipes are great if you want to maximize output for big numbers, but are you really going to go that high? What are your realistic WHp goals?

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.

Well, you won't have to worry about that. Even with a 3" GTM cat-back, you will not lose low-end torque compared to stock.

XwChriswX and others were already discussing the topic. I'm just adding to it. One can only expect that exhaust-systems will be discussed in a thread on a turbo-kit with 150+ posts.

So long as people recognize this thread is in a Tech Forum and not OT, it shouldn't turn to crap.

But going back to XwChriswX's question...I don't see why going with the bigger exhaust now would be cause for concern, unless it it involves a noise/volume issue. In that case, I haven’t heard much about the noise-levels of GTM's 3" exhaust vs. other options.

One thing to keep in mind ... 3" on a N/A car is louder than 3" on a T/T car. Those TTs are damn good mufflers.
