Finally installing Borla exhaust

20Sierra20 · January 16, 2015

Ordered the Borla Atak exhaust on boxing day... finally received it so putting it in this weekend. I'll post a vid once I have it up and running. Any tips to make my life easier tomorrow when I start pulling the stock exhaust out? I have jackstands so hopefully those are high enough!

Thanks in advance!

i didn't take a bunch as I didn't see this until after, but I'll write up a good description on how I did it tomorrow, and snap a couple quick pics underneath for the tricky parts. Did it by myself, with no lift just a jack stand, took some wiggling but I somehow managed to make it go

Did take a couple...

First thing I did was drop the spare tire and move it out of the way, does wonders for space.

First step is to remove the clamp from the stock exhaust right behind the cat, I did have a bit of trouble because there's a clip in the top holding it in place, so I ended up taking the bolt completely out so I could open the clamp up as much as possible.

Then I pulled out the hangers out of the rubber holders. Then was the hard part. I started to drag the exhaust back and twist, turn, roll it until it got stuck like this.

The muffler was stuck between the axle and the body lol. So I jacked the tire up 3" and stuck a jack stand under the front leaf spring mount on the passenger side, this made the suspension droop while keeping the body up and gave me enough room to roll the muffler completely over and slide out the back.

Once I finished all that it was easy. Just start at the front and start putting the pieces in. Make sure to lube up the rubber hangers first, and not tighten the clamps until it's all in place. Then my dad gave me a hand squaring up the tips at the back. Helps to have someone hold it while you tighten clamps. I went from the front back. Last note for the dual split side would be the directions don't make it very clear but on the driver rear, you actually mount the hanger using the hitch bolt.

Here's a picture of the finished product. Tips ended up about 1.5" behind the flaps. Had to play with positioning at each connection (slide them apart a bit) to line them up. I used a marker just to mark 1" of overlap to ensure I had enough overlap.

I love the ATAK can't wait to get one. Does it sound loud enough at full throttle? I want it to scream and make sure everyone around me knows whats up.

It's definitely loud at full throttle. Was driving home from site last week and another crew member behind me told me he could hear me hammer it over his blasting radio.
