Exhaust advise

Looking into upgrading my 2018 HB Touring CVT stock exhaust. I have looked into greddy and injen exhaust's. One's almost double the price of the other. Anyone have either installed in their HB? I am also running carb compliant 6+ basemap hondata tune on my car, as I live in California. Could I run the same tune with the new exhaust? Any help or suggestions would be greatly appreciated.

I had the injen for the civic sedan. It was 3" straight pipe with a muffler delete and the droning was terrible.

Just throwing my 2 cents in. Avoid exhaust on a cvt. It just doesn’t sound nice whatever you do because of the no shifting thing. It makes you sound like an annoying loud electric car with terrible drone. If you want to just be a little louder, just go with a muffler delete. It sounds more aggressive and you won’t get the terrible rasp and drone if you keep the rest of your exhaust stock.

Thank you guys for the advise. Much appreciated!

I would disagree. There are some nice exhausts that make the car sound good regardless if it's a CVT or manual. It doesn't add much to power but if you want a better growl coming from the car then an exhaust is worth it.

For sure. I just personally wouldn’t shell out the money for an exhaust on such a small engine. I went full turbo back on my 10th gen with a catless downpipe, straight through resonators and mufflers and bigger piping. It sounded like shit imo. I’m sure there’s other ways you could go about it and get a good tone, but the no breaks in the exhaust note or hearing the climb of RPMs reaching redline was a big turn off for me. But it’s your car. You do what makes you happy!

I installed a Flowmaster DBX series muffler with muffler delete. It replaces the resonator and gives a deep tone with very little droning. Very happy with the switch. Gets better gas mileage too and it breaths so much better.

Or an exhaust like the 27Won which is designed to eliminate drone.
Most Vette exhausts have drone except for Corsa, who spent the time to eliminate drone.

Have you checked out the 27WON Exhaust for the HB Sport and Touring? We put alot of developing the exhaust to provide good volume with minimal drone. We did this with unique "side-branch" resonators that are tuned to cancel drone at specific engine RPMs.
We have a handful of design blogs that show the development that went into this exhaust if your interested. If you have any questions lets us know, we are always open to helping the community learn.

how is it for 1.5T CVT

I would avoid aftermarket exhaust in Cali altogether just to not have to deal with a fix it ticket if you get pulled over. The other problem is, if you need to put the stock exhaust back on, you probably won't have it laying around unless you have a garage to store it in as they are one piece now.

I dont think a catback matters as long as cats and header is stock. Sure others will chime in

I believe he means being pulled over for the noise.

Testing was great and we've had many CVT owner purchase the exhaust and love it. We have a local customer we work with for various other test fits. He has been loving the exhaust so far.
