Awesome sound, not tto loud.

I could not hear the stock exhaust on my new WRX so I researched which exhaust system would not be a pain for daily driving. This exhaust is perfect. Just enough growl that it sounds great without annoying drone. It's also very nice looking. I love everything about it!

Great price and fast shipping as well!

Good quality part great place to buy from.

This system is a good choice over stock, it doesn’t drone on the highway and it doesn’t scream at everyone on the street. Import image racing was the least expensive that I could find and got it to me quick will definitely do business with them again.

Thanks so much Joseph! We really appreciate your business!
super neat

beautiful construction

Great Exhaust & Great Service

The R400 turned out to be everything that I wanted, plus more. The overall quality is great & it looks amazing on the car. The sound is also a huge upgrade over stock. It’s deeper, without being too raspy... Not to mention that you can hear the stock BPV a bit better too.

On top of all this, Josh & the team did a great job of taking care of me. Fast shipping & great service. They answered all my questions in a very timely manner & made sure that I had everything to get the project done. It is highly refreshing to see a company that offers good pricing & is still very invested in creating a personal relationship with their customers. I got a great product, from a great company, at a great price.
