GReddy Exhaust Manifold???

[Howaitoguru]

Does anyone know any information on this? How would it compare in performance to some UEL headers? How would it pair with a GReddy Evo GT exhaust. Will it fit on a 2016 BRZ?

It says Greddy at least. Go for it. Honestly, after doing the whole I-H-E path, I went back to stock and don't really notice a difference. The tune helps, everything else is just like emptying out the change in your cupholder to get the last few pennies.

What’s the I-H-E path? And I’m trying to get the most power out of my BRZ NA until I can get another vehicle then I’ll probably go the FI route. That’s why I want to do some aftermarket headers and a tune. I was just trying to find information on this.

Intake Header Exhaust


Odd how it couldn't be felt. According to all the posts I've read it "really wakes up the car"

I mean I notice some power from my drop in filter and exhaust running 93 octane. But I’d like some headers and a stage 2 tune I feel like I’d be able to tell a difference.

It does make a difference, but this is all relative. The little bump in power and drivability I felt was better earned with just the tune, and a proper wheel/tire setup. I sold my exhaust mods to test this, and found that I was right - most of what I felt was in the tune, the exhaust mods did almost nothing except pad my ego. I do no have access to E85, so E85 may offer a lot more. That's tuning again, though.

As explained, intake, headers, exhaust. They're common upgrades. You can get some power out of these mods, but if you'll go FI eventually, try to wait it out. Get the car tuned, get some suspension mods and tires to feel faster and see what life brings. If you go turbo, there's a good chance those headers you spent $1,000 will get taken off and need to be sold, ouch! Whereas the tuning software you purchased will be necessary for FI anyway, so you'll be ahead of the game in terms of money spent.

It's all in what you want to do, that's why cars are fun I just wanted to share a different perspective.

Now I can quote. Go figure...


I appreciate the info. I may try just a tune first. Why not



What wheel/tire setup are you using?

The wheels aren't that great, they're Sparco Assetto Gara 17x7.5. I run the Falken Azenis RT615k in a 215/40R17 to save weight and still have good grip. Any lightweight wheel/tire combo with this car really brings it to life.

If I had a stronger budget, I'd be on a sub 17lb wheel like the RPF1. Just don't make the mistake of getting a light wheel and then putting 26lb tires on them.

Tiresize.com has a comprehensive weight list of most brands and sizes. If you look up my tire, you'll see slimming to a 215/40 from a 215/45 dropped the weight from 23 to 20 lbs. The downside is that I have even more fenderwell gap than a factory car, but oh well.

Cool, thanks. I figured you meant light weight. I'm only a couple of pounds/corner lighter than stock now but hope to improve that. Budgets...

Punch out all cats, then tune.

Profit.
