Vincent@27WON · Apr 17, 2019

Well, it has been a super long journey and you guys have been with us the whole way. Extensive R7D, tons of design work, new manufacturing methods, community collaboration and more have all lead to this.

The 27WON Honda Civic SI catback (front-pipe) back exhaust is now ready. Click the link and check it out below. If you want more info just read through all the blogs or search this very forum and see what we did.

Me and my team hope to be seeing many of these on the street in the future.

If you get the full turbo-back setup, what's the size of the down & front pipes?
is it the full 2.5" all the way back w/o pinches?

what was the reason for going with 2.5" vs 3"

Thanks

It's a 3.125" starting at the downpipe then tapers into a 2.5" for the rest of the system with no step downs and pinches.

We did 2.5" because it keeps weight down, fits better, and still flows enough for power goals of up to 450. As well no exhaust out there is a true 3". They are are all 76mm and have neckdowns at the start where it attaches to the front pipe. So a true 3" still does not exist.

I have a question. If I upgraded the exhaust will it affect the performance or gas mileage in any way? Will it void warranty as my car did 4000 miles only. I am asking this as I don't wanna argue with the dealer if I get any issue with powertrain down the line

Any idea when the coupe exhuast will be released?

It will increase performance, More so if you are on a W1 turbocharger or something bigger than factory. All else remained unchanged you will see no change in gas mileage. But generally, we like turbo noises and have a tendency to get into it more. The warranty can only be voided if the cause of the said "broken part" failed due to the exhaust itself. An example they can't deny a faulty water pump and say its because of the exhaust. Those are unrelated systems.

To begin, I have one of your motor mounts ( I haven't tried it as my cusco suits my current needs) I truly love the fact that the exhaust is smooth, as in how the fit of it looks. Above and beyond what I have seen. I currently run a MAP street exhaust. From downpipe back, and its fitment is subpar. I also just ordered the stealth axle back portion from them as the sound was to much for my liking. I was pre order, so I could have has 2 exhausts for the price of this one. And they offer military discounts. (Something companies don't seem to understand hold immense weight as it's a huge tuner community) but again. MAPs cost, the fact they don't sell your products and a few others scare me.

Ooooh.. that sound... sounds so good. As 6SiX6 has asked, any idea when the coupe version will be released?

We don't have any resellers or distributors by choice. Right now we are focused on growing our brand, product, R&D, and making sure we give the customer the best possible experience end to end. We can only do that if we handle it.

@Vincent@27WON in the sound video, how were you recording the sound of the exhaust? Was it strictly from the drone or did you have a mic attached somewhere close to the exhaust tips?
