I installed the Borla (non-GM) Touring yesterday.  Actually a bit louder than I thought it would be, but sounds great!  When I went out this morning I noticed that there seems to be a drip of water from around one of the clamps?  Anyone know if this is indicative of an exhaust leak or normal?  When I first started it yesterday, I did not hear anything that sounds like an exhaust leak...

Has anyone gone ahead and had the joints on their Borla Catback system welded vs. sticking with the clamps?  I have water leaking from the clamps and while I'm almost certain there's no exhaust leak, having the joints welded would ensure that there's no exhaust leak and would eliminate the water leaking from the joints.  Anyone gone this route...any cons?

I put my Borla Atak cat back on myself and was wondering if I should have it welded, my mechanic said that as long as everything is tightened properly that there should be no problems. I know that there is a small hole in the can for draining, so if you’re experiencing a leak from there I wouldn’t think it’d be a problem, I’ve had no leaks from the joints that I’m aware of after 15k miles with it on, so you may just need to snug things up a bit. I’m no expert, just figured I’d give my two cents worth.

Thanks for chiming in.  Ya, it drips from the hole in the can in addition to most of the joints.  I can actually feel the air blowing out when I put my hand over the hole in the can with the engine running, but can't feel or see anything (other than the drips) coming from the joints.  I'm thinking if there was a true exhaust leak, it would be noticeable...especially with me lying underneath the truck and checking the joints with it running!  Mostly a piece of mind thing for me, since I installed it myself and just want to make sure there are no issues.

It could also just be humidity in the air, just a speculation, feel free to roast me if I’m wrong

I'm not worried about the liquid, as it's just a bi-product of cold air/pipe - hot exhaust.  My concern is around there being an exhaust leak at the clamps and the liquid dripping from them a sign that there indeed is an exhaust leak.  Water leaking out of the tailpipe is a normal occurrence, but not sure if it should be leaking from the clamps/joints.

Ah gotcha, not super knowledgeable on the subject but I probably wouldn’t worry about it if it’s in the exit pipes past the muffler, if it’s in the pipes before the muffler there might be cause for worry because of the loss of back pressure, but assuming you still have the factory cats I wouldn’t think there’d be a problem

Switched up my exhaust from a side exit behind the rear tire to in front of the rear tire. Has a little deeper tone without the extra pipe. Still very little drone and more sound in the cab which I was hoping for. Let me know what you think.

Looks great! You should level it out, I’m looking at a BDS leveling kit and if you’re keeping the stock suspension it’ll run you under $150 excluding labor if you’re having someone put it on

Been watching your videos on YouTube! Looking to get a venom 250, can't decide if i want to leave the resonator or not. Cruising speeds at 75 can you still hold a conversation?

I'm not familiar with the Venom but I have the Carven R which is practically a straight through muffler and I can hold a conversation just fine.

Yes at cruising speeds it isn't loud at all in the cab.

Just listened to your new vid plus the older ones where you had it positioned behind the wheel, as well as the before and after the Corsa tip.

 

So, you got rid of the resonator and third cat and only have the muffler.  You say no drone, or minimal drone while cruising on the highway around 70-80mph eh?  This exhaust sounds really good, sounds sick at idle, especially when you put it in D lol these trucks have a good lope to em!!

 

What kind of sound difference did you notice between the single exit and twin exit tip?

 

I'm getting tired of driving around stock and was really hoping to do a Corsa, but I'm now a new home owner and reality is I can easily justify $300 on an exhaust, not $1100 at this time.  I don't want to drive stock for another 2 years or so. I think what I'd do is buy this muffler, take it to a shop and have them remove the factory system and then just fab up a quick cat back out the one side.

 

Edit: just listened to your highway pull vid.... man I miss that sound!!!!

      What have you done to your K2 today?

      By mysery1 · Posted

      I have a 2018 Silverado Custom with 156k on the odometer. In the last month I've replaced the plugs, wires and the driver side engine mount. My wife just returned from a trip of about 1500 miles and told me the brakes are making a grinding noise when applied. I drove it and looked it over and this is what I found with the driver's side rear rotor.   I'm going to order new pads and check about having the rotor resurfaced. Hopefully this is easier than the last 2 jobs.   Peace

      5.3 / 6.2 valve covers / oil burning

      By FiLo · Posted

      Any update if the new valve cover help with the oil consumption?  I have a 2014 GMC sierra and my truck is consuming a lot of oil so I’m wondering if replacing the driver side valve cover will stop some of the oil consumption. Thanks

      primary drive belt tensioner

      By Deadwood · Posted

      I bought belts and pulleys for my '20 L5P at Rock Auto a couple years ago. I have used them for many years, and almost always save significant money, especially when I buy maintenance stuff ahead of time.   They carry many OEM parts, which is all I use unless an aftermarket is shown to be same/superior, or if it is an insignificant part or unavailable OEM part anywhere else. RA is usually lower priced, often by a bunch, but parts are sometimes unavailable or out of stock, and I do shop around and sometimes find better prices at other sites.   Be aware that you pay shipping, and if you buy multiple items and they are coming from different warehouses, the shipping can kill the advantage. Planning ahead is best if possible.   If you have a transmission service in the near future, check out their OEM (AC Delco ULV) fluid, usually MUCH less than anywhere else.

      10L1000 anyone with High Mileage ? I hate Damocles....

      By Deadwood · Posted

      New member here, very long time occasional guest. Saw this thread, thought it would be a good time to contribute someting. It is only my experience and not a claim that everyone will have the same.   I bought my '20 3500 L5P new and have put 99.9% (literally) of it's current ~400k miles on it myself, with over 50% of that towing loads between 4k to 15k, and to me this truck has been nothing short of amazing. For the first 235k I had zero issues, and from there until 321k I replaced a NOx sensor, two failing glow plugs, and three of the notorious injector connectors. I believe this truck is in part, a testament to good luck, but also good care and following a decent maintenance schedule (I also keep meticulous records.) As a result, it looks as good as a well cared for 70k rig, up and down, inside and out.   At some point before that 321k mile mark I began to get a little spooked about the 10L1000, especially the valve body. Word of mouth about potential issues prompted me to jump on the net to sift through all the noise and determine what all the fuss was about. I routinely take long trips, coast-to-coast and points in between, so roadside breakdowns can be '...a thousand miles from nowhere' and a bit of a challenge, and though I had no issues, my guard was up and activated.   And then I stumbled across a chance to salvage some parts off a new 2025 that had been wrecked in transport. I grabbed a few wear items (alternator, pulleys, etc.) and on a whim asked what the ten speeder would cost me. It was cheap...really cheap. I knew some changes had been made in the '24+ version 10L and were supposedly not compatible, but I called service/parts at my local Chevy dealer and asked why and they didn't know. A call to a well known aftermarket transmission outfit revealed it was very likely it would be fine, but to them not 100% sure.   Because it was cheap (really cheap) and I was spooked, I took the chance. Had it installed by a local shop and it worked like a champ, shifted just like the original. At it's first service at 37k, I had the shop put in a Next Gen valve body kit, which after some initial hiccups and rough shifts, smoothed out though with somewhat firmer shifting.   All that said, I have a very serious concern about my newer transmission as just two weeks ago it suddenly began to exhibit a strong reluctance to engage forward or reverse. It was a bit past due anyway so I took it in for service. The reason it was sticking was due to 'glitter' in the fluid clogging the filter...not good folks, often indicates a converter giving out. We ended up going ahead with the new filter and fluid, first to see if it would move and shift, and then if so buy me a little time. It did, and I've driven it over a thousand miles and it is shifting smooth, no noises or slipping. Regardless, it looks like a third gearbox is in my future so I can resume taking long trips with some confidence. In the very short term, my curiosity will have me examining the fluid to check how much glitter has reappeared.   An earlier poster had alleged, in the context of 10L100 failures, that it is another example of how we seasoned citizens somehow descend into hysteria, lose control of our senses, and react irrationally after brief encounters with the idiocy of the internet infosphere. Let me say (and I have used and abused said internet since it's infancy) there is no segment of the populace that has a corner on over-reaction to digital garbage. Just as my offering of experience in this arena is purely anecdotal and should not be considered gospel or all-encompassing, I believe it is still worthwhile information to consider, along with other relevant anecdotal experiences about things like complex transmissions, especially when balanced with other sources.   So to answer the original question, yes I got high miles out of my first 10L, trouble free for 321,000. Now I really wonder how much longer it would have went. Did I 'overreact' to the internet ghouls by replacing a 'good' one with a 'bad' one? Maybe. Who knows, the thing might have taken a puke a 100 miles later. So I'll just fix it again, then move on and start thinking about all the other stuff that will eventually wear out. It still has the original brakes (they're at ~60%), original injectors/pump, turbo, water pump, etc....pretty much original everything. Knock on wood.

      6 Speed vs 8 Speed

      By swathdiver · Posted

      At peak temperature.  They get to cool down and warm up more, especially those with the external cooler.  I have three GMT900s and one of them has over 225K on its original transmission.  Fluid gets changed about every 36K miles, all of it.     It's not the bean counters, it was the government.  They had to meet CAFE standards and other government requirements.   To get around that, we tune them and modify them to our liking.
