Fast shipping, it arrived on time, great item, well built, I install it on a 1995 Chevrolet Tahoe , 2dr, 5.7,with JBA ceramic headers , a 12″ , 2.5″ x pipe , the sound is awesome, is quiet at normal RPM , but it rumbles at acceleration and speed. It ‘s not as loud as the flomasters and other brands. The sound of Borla’s is unique, this is my 3rd Borla, the other Borla is the S type, which is much louder and is install on a 2003 Mustang Mach 1, is music to those that like to hear the nice sound of a racing car, it rumbles and growls like a beast. The 3rd is the Turbo, witch is much quitter than the other two. All 3 would give you better acceleration, fuel economy, more throttle response and the sound is one of a kind.

Yo originalmente iba por un Magnaflow y al final me decidí por este y no me arrepiento al pisar el acelerador se escucha pero es un sonido agradable muy recomendable.

I changed a horrific cherry bomb muffler into this BORLA.The droning sound inside was unbearable.Now with Borla,it is better!Still good deep sound,and perhaps a bit better acceleration.If the droning sounds very bad /loud,pls take a look at Helmholz pipe or j-pipe.Big help,for little money! UPDATE.. 1year and it is gone.Need to change.!Droning is a killer inside the cabin.

On my 1992 Miata, the exhaust setup is: Flyin’ Miata high flow cat -> Vibrant Ultra Quiet resonator -> Borla Pro XS. The Borla reduces the annoying boomy low tones much better than the Megan Racing resonator and muffler (2 components) it replaced. It also lets through more of a throaty tone that’s satisfying to hear but not raspy, likely helped by the Vibrant resonator further upstream. Can’t speak to this muffler’s longevity yet as it’s only been on for about 500 miles, but it seems well-made enough and I’m optimistic. The Borla’s metal was very easy to weld to the rest of my stainless steel exhaust.

I put these on 5.7 2019 Charger. I have a resonator delete, still have the stock cats on and two Pro XS mufflers. These mufflers are not loud, they are maybe a touch louder than stock, however the tone is superb and that’s what I was going for. These sound great when putting the power down. No drone, in the car you can’t hear what they sound like, I had to film myself and do a couple drive byes to hear what they sounded like. Just a great sounding muffler for people who don’t want to piss off the neighbors or make the ride in the cabin uncomfortable.

Had this installed and I am pleased with the results. Not super loud but does have a slight drone at around 2500 rpm. Has a nice deep growl on my ‘23 TRD OR. Would definitely recommend

I installed Borla 40358 ProXS Performance Muffler on my 2024 Hyundai Santa Cruse Turbo. I wanted more performance and better fuel economy. It has a very low growl at idle and opens up when you accelerate, with no drone, also my MPG increased by 10% too! Very pleased with it!

Installed on my ‘20 Sierra and it woke the 6.2L up! Very reactive, yet has a good low end without being too obnoxious. Love it.
