What I Had Hoped For

Autoanything gave me great price. It was installed by my friend who has auto repair shop. It took him about 1 1/4 hours to install. I have an Off Road model of 2018 4Runner. He needed to use a longer rear tailpipe hanger to avoid potential burning of back bumper cap. System sounds great. Good rumble, but not too loud. No interior drone. My wife likes that. Really noticed an increase in power and acceleration. Too bad K&N Intake system isn't legal in WA State. Could make it even better.

Received Borla exhaust systems or my Toyota 4Runner Trail. Decided to have system professionally installed which was a good thing. The exhaust pipe is too close to bumper and bracket had to be cut and rewelded. This is something that Borla will need to fix otherwise DYI enthusiast will need to address the fit issue during installation.

The sound of the Borla exhaust on my 2018 4Runner is Awesome!

Love the sound of the Borla exhaust compared to the sound of the factory system. The Borla is loader during hard acceleration, but nice on quiet cruising on the highway - the sound is a perfect balance! I highly recommend this system. Took me 55 minutes to remove the OEM and install the Borla exhaust. Fits perfect and looks really cool.

Totally Satisfied

Looks great, sounds great, fits great. The sound is a solid growl when accelerating, and near silent when cruising, exactly what I wanted. Plus I'm already seeing performance and mileage benefits along with my aFe intake.

Overall very happy with my decision to go with Borla. AutoAnything delivered as expected. Borla has the perfect sound and installation was not to difficult with help from a friend. Gas mileage has improved and what I like most is the performance increase.

Easy to assemble, looks good, sounds great. Haven't figured out the mpg, or power yet, but I am eager to see the differences.

Happy 4Runner in Kalamazoo

Growing up in the muscle car era, I still want that "put ya back in your seat" power or at least have it on tap. However, a have stayed married for 29 years and wanted to keep it that way, when it came to aftermarket exhaust. My chat with Mike at your place set my mind ease when it came to ordering the Borla system. No drone, but just a note that says "not factory". With a cold air intake and wide open throttle, holy crap, that 4.0 V-6 felt like a V8. Great engineering and sound.

Great Exhaust System

Would have rated 5 star on quality, but I also had fittment issue on the tip to rear shirt clearance. Other than that great sound, ease of installation.

Very good exhaust. Sounds very sophisticated and not like a teenager's exhaust. Easy installation on my trail and increased power and performance. I would recommend this exhaust to any person who wants an aggressive sound and improved performance.

Good exhaust! If you want an exhaust that doesn't sound like a redneck or 20 yr old kid designed it in a muffler shop then go with a a Borla.
