    • Update** Legit. Great exhaust note, nearly zero drone, excellent fit.
6 month update: still as impressed as the day I put them out. Zero rust. Have held up great. If your on the fence, just press buy. Original post: The took all of 45min to install. I was concerned about them being too loud but I decided to give them a shot. I'm glad it did. The welds looks nice and the overall quality and fit is excellent for the price. They mounted up easily and they were even in the factory exhaust location. They sound great, and aside from a growling exhaust note there is actually less low rpm drone. Those with a WRX know what I mean, the loud drone resonance of the stock mufflers. Either way, aside from a fairly loud startup when cold they calm right down and make just the right amount of sound without waking up the neighbors or droning endlessly. ... show more

    • Lovely
Relatively easy install, amazing sound, can’t beat it for the price. Some say the fit around the rear cutouts was off, but mine fit perfectly with minimal adjustment.

    • Fits 2022 wrx just fine
Product was installed in less than 15 minutes. For the money it sounds extremely good. Gave it 5 stars because of how good the quality is, only minor issue ,if you want to consider it a issue, is it slightly touches the plastic molding of the car but not enough to cause damage. Overall great product

I was a bit skeptical when comparing these muffler deletes to others on the market, but I was very wrong to assume. Right out of the box it was apparent that these are top notch quality with good welds and nice materials. The install was a breeze; made easier by the provided hardware kit, which I was thankful for as northern fasteners don't come apart easy. I'd after hearing this exhaust, it's comparable to the other muffler deletes at a much better price point. I'd buy this setup again without questions and I'm glad I didn't go elsewhere. ... show more

    • Works for 19+ STI, looks and sounds great.
I was worried about this not fitting my 2021 STI since the 2019+ mid pipe is different. This fits perfectly. The tips are of nice quality and the welds look nice. Overall great value and sounds great. It’s loud, but not as loud as you’d expect. And for the price, you can’t go wrong just trying it.

    • Easy to install
Very easy to install. Only issue is they hit against bottom of bumper very loud also. May look into something different. But works for now
