Remark Boso Axleback Exhaust Stainless Tips Subaru WRX / STI 2015-2021 | RO-TSVA-SL

Sounds great. Definitely a lot louder than stock exhaust. Especially with cold starts. Stock exhaust was nice but hated not hearing the car rev or really anything during daily driving. This Boso exhaust definitely did the trick to fixing that. Easy to install put the car up on ramps , took off the stock exhaust and installed the remark Boso exhaust all within 30 minutes . Great simple upgrade to do for an awesome price.

Got here as expected. Packaged well and no missing parts. Quick install and sound great.

Overall pretty impressed with the BOSO’s. Good welds, good fitment, and they sound great. There is a slight drone at highway speeds, but I do have it paired with a j-pipe.

Great sounding exhaust. Not too loud but enough to give a non oem sound as well as looking better than stock.

Very happy with the muffler delete the tips are super unique.

The quality of this product is superb. Install takes about 15 minutes. This would vary from person to person depending on tools available.

I've installed this both on my 18 and 21 WRX. However, 75mph to 115mph the drone was pretty rough on the factory midpipe. Installed the Remark resonated mid pipe and this resolved the issue.

I cant compare to any other brand or exhaust but this is EXACTLY what I was looking for, for my STi, that deep rumble. Hardly any appreciable drone (depending on person to person) or annoying frequencies. Install was done without even lifting the car lol. But needed two people.

Was hesitant on ordering from IIR as I have not before and some of the google reviews dont inspire confidence. But you cant always rely on other peoples reviews for various reasons. I ordered and they had the product out same day. Cant ask for more than that when this is out of stock everywhere else.

Sounds amazing, looks good on car and install was less than an hour. Put on 2020 STI.

Amazing.

Can’t wait for the mid pipe.

The sound of this exhaust is amazing! Lots of pops and bangs from it and it simply looks amazing too. I love how the tips slightly stick out from the bumper. I was able to install these by myself in under an hour. PB blaster is a life saver to get the stock hangers off!
