What do you guys think of the before and after? It definitely sounds better and seems to pull a little harder in the higher RPM. The first video shot during the daylight had stock exhaust with a little intake work.

The second video shot at night is with 2in exhaust after the cat feeding into Borla mufflers.

I think it's quicker in the first video. You didn't launch the same in each video.

 

I didn't get my RPM's up before releasing the brake in the second video. I still think it pulls harder throughout the power band in the second video.

 

It pulls about the same in both vids... Sounds pretty good with the exhaust...

 

Sound bite #1 makes my ears feel better than # 2 which don't do it for me..

 

I'm kind of torn. I like the sound before I added the exhaust but I was still anxious to get a deeper sound out the back. The Borla is great but I'm not a big fan of the loud drone in the cabin. I even added an aftermarket resonator but I don't think it helped.

 

some sound deadening product and mass loaded vinyl barrer can reduce road noise in the cabin. it's possible you are exciting a mode or resonant frequency in the cabin now. i guarantee Honda engineers make sure the OEM exhaust tones don't correspond to resonance frequencies with the vehicle.

a DYNO is the most consistent way to evaluate bolt-ons, IMO.

 

What's that called K- Hope- Alive ...dyno mat if I remember correctly?
