Did you end up fitting these yet?
I sure did. It's still pretty loud. Quiet mode doesn't sound like shit anymore. Normal mode is loud but not corsa extreme loud. Not as high pitched either.

Track mode is a symphony of sexual noises with nice pops and burbles on deceleration. I'm very happy right now. It would be slightly difficult to add additional resonators unless the OD is 3.5". The exhaust tunnel seems smaller on my 18. But I know it's not.

In quiet mode is similar to normal with a res delete but a tad louder. Normal is louder than track mode was.

Just as an update. FBO with the bullet mufflers on in track mode.

That's a supercharged civic on nitrous and a tire. I was spinning earlier doing 40s in 2nd. 3rd was definitely too high

Vibrant 1794s (3" in and out, 12" long) did the trick for my ARH LTH to Corsa Xtreme setup. Calmed down overall volume some, tamed some of the rasp. More refined if you will.
Do you have any sound clips by chance?

Sure here are a few before and afters...

Warm start before


Warm start after


WOT on dyno before


WOT on dyno after


Clips don't capture true difference but gives an idea.

OP are you running stock cat-back with your catless headers?

Awesome. Thanks. I have ARH long tubes with cat deletes and MBRP Street. I'm looking for something to quiet it down some. I knew what i was getting and don't expect to be super quiet. Just looking to quiet it down some. Smooth it out.

The first start up is the stock exhaust. I went catless with long tubes because I'm boosted.

Got it. I will tell you the resonators do also clean up what I read one member describe as "an old truck " sound at idle. As you mentioned smoothed it out, took the edge off, refined it some, decreased some rasp and took the over all volume down a bit.

I used MBRP 22" body 26" overall length to get my system in order. I also have the small "8 resonators up front where the cats used to be. With the H crossover this really sounds deep and no rasp, driving around it's not too loud at all, but when you hammer it she wakes the dead in a good way.

Here I am about to go catless with the Krona catback from my current catted ARH setup with Vibrant 1794's on a Corsa Sport, lol. Expecting a volume increase, but not drastic from where I'm at now. Thankfully, the Krona has a good resonator in the mid-pipe section.

So you have the resonators where the cats are and after the H pipe?

I have the long kit, which goes to the axle back. So it necks down from 3" to 2.5" which I doubt matters. Stock active mufflers

Ahhh ok cool. A resonated H pipe like the Borla one I bought makes a world of a difference. I plan on doing headers really soon too!

I'm happy where it's at now. Xpipes are more efficient and I love the sound they make with the coyote engine. Especially on the Gen 3s. 7500rpm really is a treat for the ears.

Please post a video once yours installed. I’m looking to do the same setup with either Krona or Thermal. I would like to hear your thoughts, on it once you have yours installed.

Did you install the resonators right after the X Pipe? Any pics of your setup by chance? Thanks for the info.
