It’s much cooler to tell people you purchased a “full turbo back exhaust system” so you all should just buy the entire system! Sounds amazing 🏎💨💨💨

[@27WON]

I mean you're not wrong lol.

[@rdeclaro21]

Can't wait to pick up the Full system. FP And all. Priced it out and plan to get it! My Friend luis and his Type R talked well about you guys. Hes one of my Gurus. Sounds amazing!

[@joshjackson2646]

Glad to see this on the market! Now to lock down the intercooler design for the SI so I will be one step closer to getting the W1 Turbo.

[@27WON]

We agree.

[@klemenkovacic9109]

okay this one is better sounding than 95% of them, i just woke up dunno if it is very laud, but it has a nice sound to it

[@Javiwho1]

I have your downpipe on my Si and it's sounds beautiful 🔥🔥🔥

[@gabaquino]

Nice exhaust! But what’s up with the price? Damn

[@raymondamoroso2049]

I'm not seeing the "slant tip" option available on your website? What's the deal with that? Y'all did a great job filling in what would be a big gap left behind by the stock tip with your slant tips but you can't order the exhaust that way on your site anymore

[@daryllcalpito]

Been waiting since winter. By far the most uniquely designed exhaust. Does it burble in slow pulls? I understand the fuel mapping is different in revving on parking brake vs neutral

[@27WON]

It makes all the sweet sounds.

[@the_batmobile0.4]

Anything for cvt?

[@joshrodriguez5193]

Just got a 2017 SI Sedan! Would love to throw on a full Turbo back exhaust that comes with the front pipe and downpie pipe right? Well they be in stock soon?

[@27WON]

We should have more ready by Spring 2022

[@gfmathomas]

How do I get a 27won sponsorship. Do I need to buy anything? Let me know.

[@thetoneezyp]

😍😍😍😍😍

[@linkinparkdrift]

What is that spoiler lip? Looks real nice.

[@tolgaayazseven9139]

Great sound. Does it make any difference on hp or requires any tuning to get the car optimized for the exhaust? My Si is stock and I wanna keep it that way till 60k except the hdmi. I am gonna get rid of the hdmi.

[@27WON]

Would depend on if you want just the FP back or the full turbo back.

[@tolgaayazseven9139]

27WON Thanks for the reply. What is the difference between full turbo back and fp back? Is there a link that I can check it out on your website?

[@KyngShadow]

So I know nothing about any of this stuff lol. My street has a lot of folks who work really late at night so a lot are sleeping during the day. And as a courtesy to them i was wondering if it's possible to install some sort of ...noise dampener thing, I think it's called an electric cut out with this exhaust system? Any issues doing that?

[@27WON]

ShadowakaBigG one could be customized to fit but we don’t offer it.

[@XxAfroThundaxX]

I have a 2018 civic hatch ex. You guys make one to fit this?

[@27WON]

At this moment we do not.

[@edshondasi737]

So this wouldn't fit the coupe ??

[@27WON]

Coupe version is in the works.

[@ashgrove07]

Available for Si coupe?

[@27WON]

Later this year it will be.

[@anthonym6659]

Can this fit a 2018 civic si? And will it need a tune?

[@27WON]

Yes 2017+ SI sedan as in the title. It will not need a tune.

[@MANILABOYYY]

Does it drone with catless downpipe?

[@27WON]

It does not.

[@maldo72]

Looks great .... damm pricey ... would be Interested in testing and do a full review of your exhaust ... can you also do this exhaust "without" the Polish look too much Chrome for my taste... If intrested shoot me a message

[@27WON]

We only offer this system currently with polished tips.

[@maldo72]

@@27WON no I like the tips just want the pipes not to be polished can that be done?

[@pavel1809]

Sound is amazing but to expensive. For me

[@anthonysylvester4166]

Catless turbo back in this video?

[@27WON]

The sound clips with our wrapped car yes, The sound clips from the white sedan with no wrap is FP-back only.

[@gfmathomas]

How many of your bolt 🔩on can I put on my 10th with the factory tune? I really like your products. Let know something. I want to start on my car by the spring break. Thank you. Oh yeah don't be the company that don't answer your family back 😒.

[@27WON]

After about 3-4 mods is when we suggest a tune. Feel free and give us a call and we can see what works best for you.

[@gfmathomas]

@@27WON here is my email address [e-mail]. I want to start with the air intake and then exhaust. What would you suggest the third part be. Also while I got you for a second. Can round tips come with the 10th gen honda civic SI?

[@MrWinged21]

you guys going to make a updated exhaust for the Civic sport w/Helmholtz resonator?

[@27WON]

We need to get our hands on one and see what all needs to change.

[@MrWinged21]

I thought that’s what’s on this exhaust? The two rounded tubes ?

[@27WON]

Correct but you were asking about fitment on the new Civic Sport where you not? If your question is if the Helmholtz resonators you see in this video are also on the sport hatchback the question is yes. We have had that design for over a year now. That's what came first which then lead to this.

[@MrWinged21]

27WON whoops forgot that came out with the new sport n/a coup and sedan . I mean hatchback sport

[@27WON]

@@MrWinged21 all good, that's why I was not sure what you were asking. But yes the hatchback sport exhaust that we offer now and have been is this same design with the Helmholtz resonators.

[@Duubly]

I know the coupe version is in the works but how long are we thinking? I need this in my life!

[@27WON]

Aiming for late September.

[@kcvu7215]

Does this exhaust really have no highway drone? I dd the crap outta my civic

[@27WON]

That is correct.

[@malecaucasian]

Will I be able to buy one of these for my sedan slant tips turboback?

[@27WON]

Is it an SI?

So is it loud? Like does it pop? Or

[@MrTyler0115]

It's always hard to tell in videos

[@27WON]

@@MrTyler0115 any "pops" come from the engine tune causing it to pop, things like duel decel tables and such. This system is nice and throaty without being obnoxious.

The specifics of the warranty can be found on our website.
