Thanks, I have looked at them, and they are def. nice. I just wanted to have some more options before I pull the trigger. If the GReddy doesn’t post good dyno results and/or sound, that may be the one. I’m really stoked about their air intake. What is admirable about the AFE products is that they post legit DYNO hp/torque gains. I’m not seeing DYNO posts for the options out there now....I’d go with black tips, but cool that they offer multiple options.
I believe Greddy would be good and more in the cheapest price range I'd say. There is also Thermal RD https://thermalrd.com/products/2016-honda-civic-si-catback-frontpipe-exhaust-system-for-coupe
Another thing to add is if you every get an intercooler. I'd say wait for Greddy's. Not saying PRL or Mishimoto aren't good or anything but wait for options on that end too.

I don’t like that they don’t post any real performance data, and not to beat a dead horse from other posts, I want to get away from the wannabe Boxster style tip. I’m okay to spend 1k on an exhaust if it’s awesome, but an $850ish GReddy may fit the bill. For instance I put Michelin PS A/S 3 on it, because I just really think Michelin’s are worth the money,pricey, but love the quality and look.

I’d be interested in HKS too, as long as it’s not a massive can. I’m old school, I had a 94 EX coupe back in the early 2000s, and like the old school cos. like GReddy and HKS. I had a Tanabe G-Power on it.
With the central location I don’t forsee a large can, unless they relocate the exhaust. But that would require new exhaust hangers and other fitment issues. I bet it will be twin exhaust tips from HKS. I’m hoping for a lightwieght exhaust from Tanabe. I have one on my Stealth and still love the exhaust note and weight savings.

So I notice that no one ever ask you guys. So my questions is what kind of tip design would you guys like to see on the SI's?

Dual is good with me. Hate the hdmi and can't do 3 pipes because we aren't a type r.

Can't stand cars pretending to be something they are not. #Chrysler

Agreed! Dual tip, no HDMI or triple or more. Do not like the Thermal one either, call me old school.

Honda Civic 10th gen SI Exhaust - think I’m waiting for GReddy 11861F1E-DC7C-4946-BBBF-5A1693BB5EFE


What about something like this? For those who may want to add to the rear bumber and complete the look. Not a round design, not hdmi looking, but some sort of pyramid like square design

I think it’s trying to be something it is not. It’s a sport compact car, not a super car Audi/Porsche style car...to each their own. Keep it simple. Part of the issue with these cars is over styling, fake vents/junk. Simple/clean/sleek

I like this design but without a dual outlet diffuser it's impossible. Only thing I would change is make it single tip.
