Well I wasn't going to modify our HRV, but this is super simple and easily reversible if wanted.
I enjoy hot rodding everything and have a tons of experience. We have 3 other modified vehicles.
Not for everyone, not if you are worried about warranty, not if you like stock.
The mid exhaust resonator under the passenger door has always bugged me since it hangs down so low, looks terrible, plus the stock HRV sounds so lame.
While the US$1000 Mugen axle back muffler is nice, spending that much for minimal gains is not the goal.
A sawzall, a short length of 1 7/8 tubing, 5 mins of MIG'ing and done.
As suspected, the mid resonator is straight thru and weighs about 8 lbs.
You can see right thru it.

Pipe welded in place of the resonator. It's already dirty since I did this last week, plus I painted it all with high heat flat black VHT high heat paint.

So, from inside you can't really tell any sound difference. No difference at idle, driving around town, barely any difference under full throttle, even with the windows down.
Most importantly, zero drone. None. Note that I have already removed the air intake resonator prior to this.
Outside the HRV, it has a little more burble at idle and a little more raspy when revving it up.
It doesn't sound like my 5.0L Mustang but it now has a bit of attitude which was the goal.
Zero hp gains, 8 lbs lighter. Plus the HRV looks better from the passenger side.
It's louder in this sound clip than in real life. I hope this link works.
Total cost, about 1 hour and $10 worth of MIG wire and Argon, pipe in my spare steel pile, $20 worth of VHT high heat paint.
Of course, the resonator can easily be reinstalled if desired.
The off-road HRV guys should dump this resonator immediately for ground clearance!
