I have the Borla system on my 2008 V-Max and its been great.

 

I have looked at several exhaust pictures but never asked the question. Sorry if it ha been asked before but what does that flapper valve do for the new trucks and why is it there?

Yours has drone in it, only the GM Borla sold only by GM doesn't.

 

Oh geez what is with the no drone crowd around here! COME ON lol. If you are buying an exhaust and it is louder than factory you are going to have to deal with things like "drone".

 

A performance exhaust is supposed to have drone. It is supposed to have more power. It is supposed to be aggressive and be louder.

 

BORLA, can you please make a video of the ATAK system on a 6.2 GMC?? That would be awesome.

My Gibson exhaust has zero drone. And I have the AFM turned off. A proper exhaust should sound good and have no drone..

I've installed a Borla exhaust on my '15 Sierra and have no issues with drone. Unfortunately, I can't say the same for their technical support. I installed my exhaust over two weeks ago and am still waiting for them to respond to my email question that I sent prior to the installation. Maybe next time I'll go with Corsa.

A good loud exhaust will have plenty of drone and sound aggressive. The drone means you can hear the exhaust all the time like you should. It shouldnt be quiet sometimes and loud others. That doesnt make any sense.

Your understanding of drone is a little off. I had a 2011 Mustang GT with 3 inch pypes cat back and it was very loud. The only time I had drone was about 3,000 rpms cruising. It has to do with the frequency of the exhaust that causes the sound to resonate in the cab. Everything, not just musical instruments, resonate at a specific frequency. Your muffler, pipes, cab, bed, etc. all have fundamental frequencies which can contribute to drone. One company sells what's called a J-pipe that you can tune to the frequency that is causing the drone. You see those used more in Camaros and other sport cars but I'm sure it's able to be put on a truck.

I understand this I play guitar and elctronic music but I dont understand the need to have a quiet exhaust when you change to one that is meant to be louder in the first place. I currently have a magnaflow and I like to hear it at all times but I certainly dont hear any abstract resonance sounds I just hear the exhaust. I'm getting electric cutouts so its even louder. I mean for people to know my truck is a beast.

We just installed a GM Borla on a 2014 double cab. Dual bumper exit. The guy called back not 20 minutes later and kept explaining how it was worth the $$$. Great tone, no drone. He said 4cyl mode sounded more or less no different than stock.

 

The flapper valve and tune pipe/bypass pipe(?) setup is slick.

Drone is caused by hooking the exhaust together (X pipe). In the days when you had true duals and smaller pipes (2 - 21/4 pipes we had no drone. I had plenty done. There is a blend, no separation. When you have increase sound and V4 your going to have the helicopter sound , no getting around it.

I have these on my camaro as it was unbearable for the wife at about 300-400 rpm range. Jpipes solved the issue without losing the tone of the exhaust. Can use them on any vehicle as they are adjustable

      AFM Experience

      By Atlas · Posted

      When I had a Bumper subscription for a few days when I needed to run title histories on cars I was looking at, I decided to look up a few of my old/past vehicles.   My 2015 Silverado was still actively registered and it last sold in 2024 with 160k on the clock. No idea if that's on the original engine but someone's keeping it on the road or the original AFM stuff is still going.   It used 0w20. I remember feeding it Mobil 0w20 AFE for the first 30k of its life on <5k OCI's.

      Bridgestone vs Goodyear tires?

      By Chuck FB · Posted

      I can't say I have ever heard of someone getting that type of mileage out of a set of tires even though they rotated on a regular basis but without a doubt if the front end gets wear and those tires are no longer able to track straight it scrubs them off, and driving style and road surface make a huge difference as well.    However that is not what prompted me to comment as it was the new tire theme of sitting in storage waiting to be used scenario. I am sure some tires can last for quite a while in storage if its not too warm and out of the sunlight but unfortunately some tires the way they their rubber compound is formulated they can age and dry out even in a reasonably decent storage location. My brother ran into this maybe three years ago when he was looking at the tires that were on his dually truck and a combination of wear on the rear ones and noticing that the front tires had some cracks around the sidewall of the tire not far from the bead but he had replaced only the front ones not long ago with 2 of the remaining 6 he had left from the initial two sets of takeoffs he had all bought at the same time .... 10 years ago ! ( the years fly by, a truck that only gets used a bit to haul a camper during the summer and sits in a shed for a large part of the year ). That second set of 6 tires, two he had put on the front prior like I said and they had very little wear but those cracks were now present. So we go into the shed where the other 4 tires had been stored all this time and every one of them had the same cracks in the sidewalls and so in the end it amounted to throwing away 6 brand new but 10 year old takeoff tires into the dump that he got a deal on at a tire shop because they aged out. They were a Ford factory equipment BFG tire and those tires did not age well compared to some tires I've seen far older then that and did not show that type of aging. True, they always say up here anyway that 7 years is sort of a limit for age by rights, we don't have the intense prolonged heat that many of you have down in the states that just cook tires and depends on where the vehicle sits when not in use. GB, another words maybe had you bought a set of tires to store it would have been fine as long as you used them up fast enough but there are no guarantees when it comes to rubber, tires or of that other type stored in some guys wallets 😆

      Open Door Chimes When Key is Out

      By Head South · Posted

      2020 2500 HD...I had some trouble getting the key into the ignition switch but went in fine after applying some extra effort. Since then, the door chimes when open when the key is out of the ignition. Also, when I lock the doors with the switch on the arm rest, the driver door locks but then unlocks. (I can lock everything fine with the fob) The message on the little screen displays the "Engine Hours"...kinda weird.   I'm guessing something happened to the ignition switch and it thinks the key is still in there. I unplugged the batteries for 20 minutes, no change. There are a number of videos on YouTube but nothing I can find that address this specific issue. Ideas appreciated, thank you.

      Based on what I can tell, yes.   As for updating it, its a mixed bag.  Updates do fix a lot of issues, but occasionally can create some oddities.  They do more good than harm though overall.     Here's what the most current one does and a  V171 Improvements Important: Improvements will vary by model, build configuration, system, and sales region.

      Front End Rattle

      By AndrewF · Posted

      Looking for help troubleshooting a metallic like front end rattle. Figured I’d see if anyone had thoughts before I schedule an appointment with the dealer.   The rattle is fairly loud and occurs primarily when the front driver side wheel hits a bump, even fairly minor road seams. Sometimes does it when the passenger hits a bump but I don’t believe when the rear hits. Rattle still occurs when foot is pressing brake peddle so I think that rules out the caliper rattle I’ve read about. I’ve also checked the running boards and they are tight.   Most noticeable at slow speeds.    Any insight is appreciated.
