🔊 Borla 400286 ProXS Metallic Muffler - High Performance Exhaust Upgrade (4 inch) Review

Great price for a great muffler! Put this on my 2008 Tundra (5.7L) after a dual exhaust rework. It first started with removing the muffler, which made me really loud and proud, but also created more back pressure than I wanted. I felt the difference immediately after installation. Much quieter than removing the muffler, which I'm sure my neighbors will appreciate at 4am. I can absolutely recommend and I would buy again. Very satisfied!

At first glance it looks like a high quality silencer. After installation, it sounded great, performance is good too. BUT only after 2 months it started to fail. The muffler body falls off, resulting in very annoying noise, poor performance and poor fuel economy. Revain immediately sent me a new one and the SAME SAME happened in the same timeframe! I expected more from Borla as a reputable brand, but I learned my lesson and chose Mangaflow. Thicker steal, same power and sound, and it seems like

I have to say right away that I'm a Borla fan now. I've always been a fan of the Flowmaster since I built my first exhaust. I recently installed a Flowmaster catback system on my 2014 Tundra and loved the sound, but the drone killed me with its 5.7 liter engine and long nozzles. Install this Borla silencer to tame the drone and calm it down a bit and that's exactly what I got. I like how it sounds and without drones. But the roar is audible in the cockpit. People might say you have a custom…

Great option if you don't want to buy a full Borla Cat Back Kit for over 1,000. I took this to a local muffler shop and installed a real dual exhaust (not a fake "dual exhaust" like 99% of all kits with cats do anyway) and installed new pipes and exhaust tips on the 500 after all was said and done (including the cost of this muffler). Much better option IMO. Why pay a thousand or more for an exhaust that just gives you the looks of a dual exhaust when you can have exactly the same sound, if not

Well I had three different mufflers on my 2007 v6 3.5 Dodge Charger. First I had a Magnaflow muffler which was a clumsy tube in the muffler body and rumbled a bit. Didn't like the sound. Switched to the Flow Master muffler which is chambered for a decent growl and didn't sound right for my v6. I then broke that muffler through a huge sink, so I went to twin straight pipes. Dude, that sounded LOUD, but it sounded like an imported four-cylinder car at high rpm. Fast forward to this week after…

Quality control Borla sucks! 1 star for the processing of this silencer. The first muffler came with a lot of scratches on both sides of the entire muffler! I wasn't happy considering I'm paying for something new and I need it to look new! Yes, I know it will be under my truck, but for heaven's sake, check your items before shipping! Photo attached, muffler looks the shabbiest. Finally got a second one and it wasn't scratched that badly so I kept it to myself. However, I polished the thing with
