Default WHP with 3" single exhaust?

I am surveying exhausts right now, and I know I can custom make a 3" exhaust and find a universal muffler pretty easily for it. My other option is to buy a Supra exhaust system that has the 95mm piping and mod it. That is kinda how I am leaning because I don't want to buy exhaust twice.

I think a 3" exhaust may be fine for a while, but just how much power are you guys actually squeezing through a 3" single setup?

Like I said, I'm torn between custom fabbing a 3" system and getting a Nur spec or HKS muffler for it, and buying the Supra 95mm system and modding it. I'm sure the 95mm system would give me some more room down the road, but is it worth the extra cost and hassle?

At any rate, I can't find just the mufflers with the 95mm piping...

Its going to be a 2jzgte. Stock JDM twins for a while, but ultimately, hybrid twins or small single. Currently NA.

3'' is more than enough for now. You go too much larger than that while your n/a, your only killing your power. Go with a 4/5'' exhaust after 450rwhp

It should be a little less expensive finding a good muffler (HKS Hyper, Apexi N-1) and just have a good shop customize one for you. It would exactly how you want it to be

3" is enough for a single turbo setup, if you are making mad HP you could go with 4" later on but most of us don't need that much flow and over 3" clearance becomes an issue for the more basic exhaust shops.

That 95mm HKS Carbon setup for a Supra is still VERY tempting. You can get it for less than $700 new and it would be MOSTLY bolt on with little modding AFAIK...

its all in the setup, the turbo you will be running, what hp range, and where you want your power band to be. all we know is you have a gte on the way and may have a small single in the future. sounds like 3" is plenty enough for that.
If you are running a 3" downpipe then whats the point in a 95mm exhaust. see what i mean?
If you are running a 4" downpipe and midpipe, then yeah a 95mm exhaust is appropriate but at that point you may as well get a 4" exhaust all the way back.
another popular option which is my favorite is 4" downpipe/midpipe, to dual 3" exhausts to keep that SC Dual exhaust look intact.

All good info. I'll break down all the time, money, and work needed for both and make a decision that way. Sounds like performance-wise it wont matter which way I go.

I've seen quite a handful of cars with single 3" exhaust that make around 600 rwhp including the 2JGTE.
