What are your thoughts about the Greddy Evolution GT Exhaust?

dts3 · 01-28-2019, 09:13 PM

...and are the tips removable and/or adjustable?

I actually went from a custom exhaust to the Invidia and do not plan to purchase a new exhaust anytime soon (would like the extra horsepower but can’t stomach the idea of spending another $1,000 on a new exhaust). My Invidia is paired with test pipes and while it’s loud, it’s perfectly fine for daily driving. My Z is my only car.

The Greddy is a bit louder than the Invidia as it’s more free-flowing. It also sounds a little more aggressive so I think it wins there too. I would just probably switch to HFC’s or resonated TP’s to help tame the extra volume compared to my set up. Tips on Greddy aren’t adjustable like the Invidia.

Also, your vendor might have confused the Evolution GT you’re after with the old Evo 3. Hopefully that clears it up, but you should be able to buy it elsewhere if not.

I just spoke to a local dealer that I've been going through, and he said the evolution has been discontinued. I don't know what to make of this; I thought this exhaust was relatively new.

Thanks for that, I didn't even realize that there are two similarly-named exhausts. I confirmed with z1 that they still have access to these.

Fitment is great, and built quality is top notch.

I love it but it's loud asf, especially on cold started. I just added non-resonated test pipes and I feel guilty if I start the car before 7:00am or after 10:00pm. Drones like a bitch between 2.8 and 3.2krpm when under load but you'll get used to it. I just took a sound clip the other day after putting on the test pipes. I'll try to upload tomorrow

GReddy

Absof

ckinglutely love it, but it does drone around 2,500-3k rpm. No fitment issues and the welds are perfect. If you're looking for a dual system, I honestly think Greddy and Fast Intentions are in a league of their own.

Yeah I noticed that after I bought it lol. The tips stick out a bit more than I like, but I got used to that as well. I can also vouch for amazing fitment, quality welds and nice think flanges. I feel like I got what I paid for with it.

Also, for anyone looking to buy it and seemingly can't find it:
When I bought mine, every single retailer said they were out of stock with a backorder eta of several months, including z1. When I asked z1 when they expected to get more, they said had some in stock, even though the website said they're unavailable. I suggest reaching out directly to z1, maybe they still have them

Greddy made a limited number of these in 2018 and 2019, so they are not easy to find.

3 exhaust clips of varying legality. Z1 headers -> Fast Intentions resonated test pipes -> Greddy Evolution dual

So I’ve got your setup - minus headers. Wanting to add the z1 performance headers - did the headers add a lot of sound to car?

I did cams and headers together. The car sounded noticeably different, but I'm sure it had more to do with the cams

That’s my next step - cams and headers.

Noticeably different as in noticeably louder? Haha! I don’t know how much more volume I can take - lol!

Not necessarily louder, just a different tone. It's nothing like a big displacement V8 obviously, but it was choppier. It also sounded more aggressive around 3k rpm and up under WOT. I'm sure the headers played a factor there.
