Nice sound, killer look

Order arrived almost a week early. Love the single exit exhaust look and it has a nice bassy rumble. It doesn’t make a ton of noise in the cabin but it’s just enough to really notice and be super fun when you’re gunning it


We are glad to hear that you are satisfied with your purchase of the Invidia N1 Cat Back Exhaust with Titanium Tip for your WRX/STI. It is great that the exhaust arrived earlier than expected, and you are enjoying the look and sound it provides. The single exit design and bassy rumble add a sporty touch to your vehicle without being too loud in the cabin. It sounds like you are having a fun driving experience with it. Thank you for your 5 Star Review!

My new WRX

I've had my WRX for about a year and a half. I wanted louder exhaust because I could not hear the engine RPMs a lot of the time. I also wanted it to sound like the sports car that it is. This muffler looks great and kicks AZ.


Thank you for the 5 Star Review! The Invidia N1 Catback Exhaust has is a phenomenal exhaust setup! Invidia has made exhaust systems for almost every version of the WRX/STI and each one has gotten better and better whether it is single or dual exit! It looks and sounds fantastic whether you are just cruising around or giving it hell! Enjoy!

It sounds amazing

Once I put this exhaust on i was blown away by how good it sounds. I don’t have a tune on my car yet but but when I do a pull it still pops and when I downshift there’s nice pops but I love it because it’s still loud and you can definitely hear it but not to loud where you can’t even talk to someone in the passenger seat. Also the idle sounds amazing too


Thank you for your 5 Star Review! The Invidia N1 Cat Back Exhaust is a great exhaust no matter if you have a tune or stock! It brings our a great sound for the WRX/STI that you will never get with stock! Being 304 SS you never have to worry about corrosion of any kind! Enjoy the new pops and sounds!
