Third Party Exhaust Recommendation?

[VR30Infection]

I wish I had the money and time to mess around. I would buy a duel 2.5” with H pipe, duel 2.5 with X pipe, duel 2.5 merged into single 3” and then finally a full duel 3”. Then dyno all of them. Then I would test all of them with just lower down pipes and then also with full 3” down pipes.
I’m quite sure a lot of people would be surprised. There really is no need to argue or get upset. Everyone gets to make their own decision and spend their own money.

Couple things to point out though.
NA or supercharged vs. Turbo. Two different animals. In a turbo application the turbine is a giant restriction to exhaust flow. Apples to oranges. Also. In any application, the further down the exhaust pipe you go, the diameter matters less. This is due to the exhaust gasses cooling drastically as it travels down the exhaust pipes. Engine Masters tested this on a NA engine. Duel 3” vs a. y pipe into singe 3”. Didn’t matter if I remember correctly.

One thing is absolutely true is this. If you only have factory down pipes, it doesn’t matter at all. Next, if you keep factory upper down pipes and do catless lowers, then 3” is pointless. It won’t help make more power at all. Exhaust like the MBRP that is literally a 2.5” flange necked up to 3”. Again. The most important place to have the diameter opened up is right after the turbo. This isn’t an opinion.

First I went RAE motorsports Suck to Fart. 3" Titanium Intakes, just sick quality; 3" LDP's Resonated & 3" Catback Exhaust - both great quality, sound and fittment. I install everything myself so fittment is big. Then I went with a Sonictuned tune and the car was SLOW stock, I mean 12.99 60-130 now it is woken up. Will have new 60-130 times shortly - the weather has sucked.

Now, from what i have learned with performance turbo motors its all about flow and when you flow. Most of the restriction with this platform is in the LDP's. Basically if you do 2.5" on intakes, LDP's and exhaust basically all you are getting is better sound not performance, especially if you do not tune. 3" is the way to go. The tune adjusts AF, timing, knock for flow if you are not going the next step big turbos and fuel. I can't wait for EcuTek to come out with boost by gear, that will add a whole other dynamic. Without this the car was pedestrian at BEST, now it's fun.

I mean if it wasn't the case AMS wouldn't be testing 3.5" intakes as we speak.

Yep, if you want to chase power then you've gotta open open the system to 3". Mostly the turbo out to downpipe in which I described earlier as being most important. Left out the intake portion bc this thread was about exhaust but you're absolutely right. There's really almost zero price difference between the AWE 3" track system and the 2.5" Stillen version so I'd go AWE, although OP did ask about the touring model.

Love info like this for those of us that don't "know".

Love info like this for those of us that don't "know".

It’s tough because most everything is just marketing based. Creating a perception to make money. It’s rare to find a company that cuts through the crap and gives honest real world information. The best thing is to use this place as an information source. Don’t be afraid to ask questions more than once. Get info from as many people as you can so you can make an educated decision on how to spend those hard earned Benjamin’s! Plus it’s like a family! There are always going to be arguments. Grain of salt and move on!

I've got a type D Tomei and it's great. Gives a nice tone, not obnoxiously loud either.

This thread really went off the rails lol. Just looking for options other than Nismo (if I cannot get it for whatever reason) for an OEM+ dual exhaust that increases sound only marginally that fits the "intended" aesthetic of the car.

Although the ring of holes in the OEM exhaust isn't "bad" it is not really adding to the Z aesthetic. It is just a carried over part from a Q50 Red Sport. All the other exterior changes on the refresh of the Z was carefully thought out to bridge past version of the car. The exhaust just does not fit. Hence, I think a more traditional looking exhaust would look better.

The Nismo exhaust tips look nice. However, the AWE and other similar third party ones fills up the gap better. See attached. Hard to find pictures/videos of same angle.

Fast Intentions. True duel. Has mufflers. Can choose to have resonated as well to tone it down.

I have a stillen comp on order expected delivery next week. I was considering the Nismo track but decided to go with the dual 2.5” on the stillen over the 2.25 on the Nismo.
