GR Corolla Street Edition Valved Exhaust Quad/Triple Exit

An absolutely amazing exhaust. The quality and welds are like artwork. It was easy to install and sounds amazing. Makes a very nice raspy noise that fits well with the GRC’s angry three cylinder. It mellows out to a nice hum at cruising speeds with almost no drone at all. The resonator definitely was worth adding. Buy this exhaust…you won’t be disappointed.

This exhaust is really high quality and has such a unique tone! I love the ability to control the valve at will and saving 12lbs off the stock weight is a huge bonus. RK's customer service is fantastic, Rob answered my many emails promptly, including a few I sent from under the car the day of the install!

This is probably the most refined aftermarket exhaust system for this platform. Previously, I had tried the HKS Legamax, which was thought to be the most refined/daily friendly option. This might be quieter than that with the valve closed. It also weighs under 20 lbs instead of 40 lbs while incorporating a valve, mufflers I'd estimate at 1" bigger a piece, and a controllable third exhaust tip. There really isn't any other option on the market that has this mix of price, refinement, weight reduction, and customizability. Definitely worth the lead times.
