Kevin W. ★★★★★

Installed these on my 2018 WRX and the weight savings over stock is immediately noticeable when you pick them up. The TIG welds look clean and the sound is aggressive without being obnoxious.

Ryan Q. ★★★★★

Pulling it out of the box, I was surprised how much lighter the whole thing feels compared to the stock setup—16 pounds is genuinely noticeable. Installed it in my driveway in about 20 minutes, and the sound is exactly what I was hoping for without any drone on the highway.

Zoe Z. ★★★★★

These TIG welds look way cleaner than the price suggests, and at 16 lbs the whole thing is absurdly light compared to the stock mufflers. Cold start is loud but the tone settles into a nice deep rumble once it warms up.
