Invidia R400 Gemini Single Layer Quad Titanium Tip Cat Back Exhaust Subaru WRX / STI 2015-2021 | HS15STIGM4ST

I absolutely love the sound. Aggressive and deep not raspy, plenty of noise but once you’re up to cruising speed it’s not super loud in the cabin. Install went easy the shop was signing its praises however the tips were not even, I had to take it back and they heated up the rods a bit to bring the driver side end up and it still wasn’t even after that. I ended up using fuel line hose and metal tie clamps to stop the bars from sliding around in the urethane hangers which fixed it and now my OCD is satisfied and it looks amazing. The blue titanium finish is awesome. Definitely turns some heads. I live on a long dirt road so my car stays filthy hence all the dirt

Very good sound deep when you Step on it not too loud when you're just cruising.

Great looking exhaust

Amazing sound and install is extremely easy

Loud cold start, barely no drone on highway and sound really nice, overall good quality and sounds great.

Completely worth the money. I Love the way it sounds. It was pretty easy to Install

The exhaust sounds and looks great! A perfect fit for the WRX

Best purchase made by far, bought the r400 for my wrx came in within a week. Installed it and I looks killer. Definitely purchasing more products from here!

It has deeper tone and a bit louder than the q300. It’s also a great choice if you still want a bit of “rumble” and have equal length headers.

Great sound, not too loud or obnoxious and easy install. Fast delivery as well.
