Perfect sounding exhaust. Not too loud. Not too quiet. No drone inside. Couldn’t be happier. 1 hour install time. Easy as could be.

Sounds decent, could be better tho.

So I had a remark catback (resonated/muffler delete) and I wanted to get this system a try. Well, it’s just okay. That’s all. It’s a nice looking system for sure.

2 things: 1. It is indeed quieter obviously than the muffler delete, BUT, it’s a much deeper tone and it drones like crazy on the highway and around town from like 2.5-4K rpm. And with that drone come a lot of vibrations in the plastics on the car.

2. Fit and finish was 7/10. Exhaust rubs the interior of the exhaust cutouts on the bumper, and seems like there was a decent amount of unfinished metal there.

OEM STI exhaust vs R400

I have a 2020 wrx that had STI exhaust installed by the dealer. Good sound, but wasn't completely happy with it. When I installed my J pipe it got obnoxiously loud and had a lot of drone. When I got the R400 I paired it with the Killer b header. Got dyno tuned and the sound is amazing. Hardly any drone. It's actually significantly quieter on a cold start than with the STI exhaust. At low rpm or low load there is a nice slight rumble. Not like an EJ. Unique all on its own that turns into a wonderful growl. Install was easy. Fitment is still in the air. I cannot get the tips perfectly even in the valances. But it's close enough that my OCD has accepted it. 100% recommend

Perfect Sound

Great fitment from a quality product. Not to quiet, not to loud. Perfect balance of sound. There’s a reason the r400 is the most popular. Buy it!

Good Exhaust

The overal quality and build is nice, the sound is good, its a little too quiet for me though. The only trouble I had was the exhasut not lining up, tried everything and finaly just ended up using a zip tie to bring it over to the right spot. Import image racing does a great job and has a great support team! It was here in 4 days! Overal im happy besides it not lining up correctly.

Sounds nice but has nauseating drone and dangerous noise penetration. NOT FOR STI

Bought this for the WRX STI. I'm assuming all reviews of drone not too bad and etc. are coming from WRX with their ELH. This is a terrible exhaust for a WRX STI. It sounds amazing and sounds like what many of the youtube clips show but I dont think its worth the bodily damage you will be doing to your body with driving this at anything longer than 30 minutes. I work in a factory and the decibels being produced in cabin by this exhaust is the same as the machines I work with. Machines I would never work near unless I had ear plugs.
