Thank you for the review, please let us know how it goes with Injen
They basically developed the exhaust and installed it once, but really lack support. I think it’s a great system at an ever better price point, dare I say a baby magnaflow? Will get more audio clips and also stay tuned for the AA downpipe install which might make it much louder (I hope not!)

Moderate acceleration, can still hear the intake noise!

sorry for the wind noise! Gentle acceleration in sport mode. Get a better sense of the tone/deepness

Apologize for the short video. Wind gusts are like 50MPH! I promise it’s louder in person, but this does a good job to capture the tone! More videos coming! Will grab drive by and in car.


Added: Cold start = loud

Thanks for the video clips, I'm thinking about purchasing this exhaust system.

Keep them coming! It’s sounding better each video!!
The wind here is brutal! May see if I can find an empty lot tomorrow. It’s really been a pleasure. Comfort mode is pretty quiet. Sport mode has some decent volume and sounds great in the car!

Does it seem surprising, from a logical standpoint that my exhaust has 2 identical mufflers and a valve on one of them. On comfort mode, all exhaust goes through a single 3” muffler and it a little louder than stock. In sport mode, the valve flips and exhaust goes through dual 3” with identical mufflers. Would you expect a dual pipe to be much louder?? It is. I thought it would be quieter if anything, with two mufflers. Hmmmm.

Comfort is the way to go on the highway for sure. Nice and quiet. Sport is a little louder cruising, but the pops and bangs are now low booms and burbles. Sounds much better.
Yes, this is the whole point of the valve and comfort vs sport setting. Essentially air is being restricted and flowing through 1 pipe once you switch it to flow through both pipes there is more airflow. Also we don't know what they're packing in the muffler on both ends there could be different amounts of material in each.

I actually took pictures of each side before I installed! It is identical :)

That's my first suspicion as well.

Please see above. They’re identical
In the time it took me to write my comment while being interrupted at work, yours posted in between. I only saw it afterwards.

Did you happen to get any full throttle videos of this before adding the downpipe?

No but it was a bit louder in sport mode than stock, not a LOT. The comfort mode was near stock levels. The downpipe made it another step louder with more mid range noise.

OP, did the exhaust valve rattle on cold start get resolved?
I actually think I did resolve most of it….I removed the muffler section again and removed the heat shield between the mount and the motor. I also bent the clip (they have their own, you don’t use the OEM one) to gain some height. Seems tolerance is tighter but the rattle is mostly gone! Really enjoying the system with the downpipe. It’s not too loud in comfort and not any more drone than stock. Sport mode and cold starts are quite loud, I would be hesitant to run this setup catless for cold starts, but people have different tolerances for volume. I would recommend it as it sort of is a poormans magnaflow!
