Borla Exhaust Step by Step Install 5th Gen 4Runner
Borla Exhaust Overview, Sound and Full Install on 5th Gen 4Runner
We previously had an article written by the man, Blue Ox Off Road (Jeff) who installed a Borla Exhaust. This was a very early install on the website. Today, we are going to be writing a post on Jeannette’s (my girls) 2016 SR5 premium.
After we installed the MagnaFlow exhaust a while back, we fell in love. We did initially have some problems with the exhaust rattling at idle but it has since worked its self out. After a couple years of running that exhaust, we were ready for an exhaust on our other 4Runner.
The MagnaFlow has a pretty deep, throaty, beefy, growling sound which I personally love. For our other 4Runner, we wanted to go with something a little more mellow. The choice was between Borla, Gibson or aFe. After writing our article on these exhaust systems, we decided on Borla.
Borla is an exhaust that will give you much of the same power benefits of a MagnaFlow while keeping the loud growl to a minimum. Jeff said it best in his article from awhile back, Borla is the gentleman’s exhaust.
It is all personal preference, but I really feel like the Borla is the Goldilocks of exhaust systems, it will work for most owners out there. Between all of the systems out there, Borla might be the mildest.
The best exhaust system?
There is no one “best” option when it comes to an exhaust system. This is completely personal preference. If you are looking for deeper, meaner, beastly growl then you should go with the MagnaFlow. If you are looking for something a little more subtle, go with the Borla.

Step #1: Remove Spare Tire
Start by removing your spare tire. I don’t think we need to write a step by step on this one but if someone wants us too, we can. Removing the spare tire will give you much more room to work with underneath. If you do not have your car on a lift, removing your spare tire is a key step in providing space for the install.
Step #2: Loosen Flange Bolts
The Flange Bolts are pretty straight-forward. Just crack everything loose for now but do not remove the actual bolts. You want everything loose before you pull it all apart.
Step #3: Lube up those Isolators
This is an absolute must. Grab a can of WD-40 or whatever you have handy and go to town. You can use a small screwdriver to lift the insides of the rubber isolators in order to fit some lube in between the isolator and the metal sleeve. After you have you coated the inside of the isolators, rotate the isolators around a little bit so you can spread the lube around.
Step #4A: Crack Bolts on Muffler Tail Pipe
This first bolt is easy. There is plenty of room for you to crack this first bolt. On the other end, the bolt is welded to the exhaust pipe, so your only option for grip is one nut, up top.
Step #4B: Crack Inside Bolt on Muffler Tail Pipe
The second bolt on the other side is a bit more tricky. You need a long extension bar to get any type of grip on this nut. Take your time and twist hard and SLOW, you will get it.
Step #5: Remove Tail Pipe
Step #6: Disconnect Last Isolators & Remove Tail Pipe
IMPORTANT NOTE: Remove silver bracket before removing the tailpipe. This will make your life a little easier.
Step #7: Install New Tail Pipe
Step #8: Ring Clamp Muffler & Tail Pipe
I have this as a step before throwing on the muffler, even though the muffler is pictured here with the tail pip assembly.
Step #9: Install New Muffler
Step #10: Connect Muffler to Flange Bolts
Installed – Playing at the Lake
Last two are not Borla shots, just cool shots from the same day.
Just installed Borla Touring today (2017 Off Road , 42k miles , stock intake). I like the sound (little bit too loud for my preference but Hell it sounds good!) dont expect any performance changes as this part is mostly for looks and growl. Bought this for 460$ and it was totally worth it. Im not planning on replacing the air intake as it will probably make things louder.
Hi fellow Runners. Maybe I’ll get hate maybe not but my experience w a Borla free flow exhaust and cold air intake was a total waste of what I consider a fair amount of change. Had it done at a respected 4X4 shop. I have no reason to think the work done by the book. Had a chance to take a look at install while I was at a Toyota dealership and looked perfect. What did I get?, a waste of $1000 +. Yes, there was a bit of better sounding exhaust note and a loss of mpg.Total waste of money.There was no increase in power and if there was, it was negligible. My advice is save your money and buy something cool for appearance like a nice set of Nittos, which btw you can mount 71/2” tire to fit the 7” width stock tire. Forgot to mention the above work was on a 2015 Limited. I just took delivery of a 2020 TRD Off-road and had the 15’s 20” wheels mounted instead of those cheesy 17”. Tire size is 275/55/20. NO rubbing, shimmering. Toyota did have to put new pressure sensors on as they weren’t compatible with the 20”. No cost to me. I know I’ve covered two situations but that’s just me rambling. Hope all in the group is well and enjoying their sled.
Did any one have a weight comparison on stock exhaust, flow master and borla?
For the weight of the actual exhaust system, they are all pretty close. This is a pretty good question, though. We will look into the specs on this and get back to updating this.
