BORLA PRO XS review: I initially put two Carven R mufflers on my custom 1981 corvette. It was crazy loud! It was so loud that it was hard for me to gauge how fast I was accelerating when on the gas hard. Even just cruising through my neighborhood, it sounds like I’m flooring it! Too loud. So after several online searches and reading others review I decided to try the Borla Pro XS. I bought two ( dual). Omg here’s the biggest difference. It’s a tad bit quieter but because it has such a DEEP DEEP grizzly bear tone it takes away all the crackling sound from my camshaft which makes the overall muffler sound very nice, tolerable, and more pleasant to drive, and gauge my acceleration when hard on the gas pedal. It’s perfect for being very aggressive without upsetting your neighbors. And by the way my neighbors is a cop! I recommend this muffler to anyone who’s a true restomod enthusiast that still appreciates that muscle car sound but is also respectful of your neighbors too.

Borla muffler was highly recommended, instant change in performance and sounds fantastic.

Purchased this for my 2019 RAM 1500 Pentastar V6. Alot of people said not to put a muffler on a V6, but I went ahead and did it anyways! I do love the sound, but for my taste it is a bit loud during soft acceleration. If factory noise is a 2 and straight pipes are 10, I'd rate this at a 6. I could see myself removing it down the road since I'm not 17 anymore, but I do like it. Nice mellow sound on start up, nice burble when idling, real mean at WOT. DO check the muffler itself for factory defects before you install it. After it was welded on the techs noticed it was leaking, they looked where the neck meets the body and there was a hole in the factory weld. It was too late to take it off and return it; waiting to hear back from Borla about their Quality Control and "Million Mile Warranty". 5 stars if it wasn't for the shoddy craftsmanship.

I put this muffler on a Ram 1500 limited , wanted a little more growl without being obnoxious. This is perfect , love to hear it bark when I get on it , and love the quiet when I’m just cruising. Couldn’t be happier, zero drone. Took a couple months to really mature the sound of it, but it is exactly what I wanted when I purchased it.

Really amazing sounding muffler! I would consider this medium loud. Obviously considering the size of the muffler you should expect the volume to be fairly loud if you’re using it with no other resonators.

This product specifies using Borla 18006 band clamps to attach this muffler. The clamps I recieved were not as pictured and did not work. I received very cheap flat strap style band clamps that could only hold two regular 3" ID pipes together and were expensive, $91 for two clamps with tax and shipping. I emailed Borla to ask if they were aware of this and I got no response. I called support only to get their voicemail. They never called back. The muffler itself is made ok I guess but the sound is not good. Put it on a 2.3 turbo and it made it sound like a chainsaw at high rpm. Loud cold start. Not too happy with this, especially their service. A MAJOR PLUS however is that it is indeed fully 304 stainless, unlike Vibrant who are liars and use a different magnetic grade of stainless inside. Don't believe me? If you buy Vibrant than test it with a magnet and see for yourself. I am not a fan of either of these companies however. Nobody has any integrity in this industry it seems.

This Borla muffler outshines my old Flowmaster on my 95 Chevy K1500 Silverado 350 engine. It is quieter than the flowmaster, however I think in time it will open up a little. In my first city/highway drive it actually seems to run smoother than before and maybe with crossed fingers a tad better mileage and power. Time will only tell! The sound is really nice and not annoying. This is our third Borla purchase as our first two are on our 73 C10 350 that has headers with 3” out to the dual Borlas and surprisingly it is much quieter than we thought. Sounds truly awesome. If you want more noise pick a different version but this style is great. They look so nice and our hopes is they last for many years to come. We have more Chevy trucks in the family that will be needing exhaust coming up and Borla will be our go to brand!

It's good real sound of v8 , little drone in the cabine above 110km , not noisy while starting or in park

Sounds amazing! Not loud but very tight sound and when you get on it with my 5.7 hemi she sounds terrific

صوت عادي جدا والغريب لم تكلف الشركة الصانعة نفسها بوضع سهم لأتجاة تركيبها الصحيح ( المدخل والمخرج) غير معروفة وليست موضحة

Nice low rumble and no drone on my 16 Silverado 5.3. kept the resonator and ditched the flapper.

Para quien disfruta de un sonido grave pero nada escandaloso es una excelente opción. Reduce en tubería directa más menos un 40% del ruido y queda muy bien.
