Installed Borla and got a question + off-road videos

[ZR2]

Hey awesome people,

I installed the Borla ATAK catback system and the left tail pipe is a pain. It doesn’t align with the right one and its not tucked into the rear bumper. Had to do some tweaking and now it’s scratching with spare tire heat shield. Just checking if anyone experienced that. Other than that please enjoy the videos. As some videos are large i put the youtube links below:

It sounds great

I did have the same issue with my ZR2 left tailpipe. My truck has the factory Borla and it sounds great just like your truck. After the dealer replaced the engine (due to spun bearing), I noticed the left tailpipe was not tucked up behind the bumper. The dealer process was way too cumbersome (no appointments then multiple trips for assessment/repair) so I took it to a Muffler Shop. $100 and 45 minutes later and now the left pipe is matching the right side. It is not contacting the heat shield either.

Good luck with getting this resolved. I was almost ready to have the right pipe dropped to match when I saw a 2025 1500 Bison ZR2. They do not tuck up on the new ZR2's but instead show just a little bit below the bumper.

Exhaust sounds great!

They will fit right, just takes quite a bit of adjusting. Took me about and hour of crawling around under the truck and moving all the joints but ended up getting it damn near perfect. Then added chrome tips from amazon.

Would you mind taking a picture of the underneath are where the left tail pipe is buddy? If you could also show the space between the heat shield and the shock all from the bottom. Thanks alot

Just as an update, i still get the rattling noise when the left pipe contacts the heat shield especially after rough offroading.

I went snowverlanding in December in some pretty deep snow that I high centered on and it pushed my exhaust up. For the longest time I couldn't figure out what the noise was. It sounded like a vibration of a loose metal part. The truck would be in reverse on an uneven surface when I would hear the noise.

I was able to get under there while in reverse and I started feeling around while I could hear the noise, I gave the exhaust a mini Christian Ronaldo kick and boom, silence. I'm going to throw an exhaust system on it here in the next couple of months.

I also noticed when offroading and fully flexed the exhaust hits the leafsprings on either end.

 

[ZR2]

the Ronaldo kick. Yeah man its a pain honestly. I emailed Borla earlier questioning the direct fitment they advertise and will see what they say.

I'll get some pictures this weekend. You can also drop the spare tire down, loosen the six retaining bolts on the shield and move it away from the exhaust pipe. I did that on mine too.
