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.

Lol.... That's it... I'm dumber now

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

300-400?? Did you mean 3000-4000?

No, i forget what the rpm rsnge was now since it's been about two years since installing them. Just remember there was a range of about 300-400 rpm that it would hit. Was around 72mph it would start since it was really on the interstate where it was an issue

You guys need to stop talking to me like I am stupid. I am the type of guy that does not hold back and I will say exactly what is on my mind, even if it makes no sense to you.

 

I dont have any "drone" or resonant frequencies that bother me in the sense you people are complaining about, but I can definitaly always hear my exhaust. Especially since I put electric cutouts on. It is loud and aggressive.

Any exhaust is quieter at low RPMs and louder at higher RPMs, you need to prof read.

Oh for crying out loud F'N forget it then.

LOL.....No need to get upset.

 

You say what's on your mind, (we get it) even when you're totally wrong and don't understand how an exhaust system works!

 

You are correct when you said "even if it doesn't make sense to you" that's for sure.

Ya no, I do know how it works. But I do think the whole "drone" thing so many people are trying to avoid is silly. Especially since putting an aftermarket exhaust on, is somehow supposed to magically be quiet when you want, then louder sometimes, but not create any resonance, and not piss off the wife, and not make anybody upset. Lol. I just don't get all the fuss. Does everyone have super sensitive hearing or something? I have had performance exhausts on all my vehicles for the last 20 years and have yet to have any "drone".

 

Lets put it this way. Im not trying to be mean or anything. I just love the sound of old muscle cars with no mufflers just screaming down the road. When you jam that pedal to the floor and you can hear and feel the natural sound of a badass GM Smallblock V8. My goal is to have the loudest exhaust I can get. But that is me. If someone wants a quieter exhaust, go for it. But I see alot of guys compromising to try and find their ideal sound without any drone and it has been hit or miss from what I've seen, because its hard to control what will happen once that exhaust is there. Which leads to guys swapping exhausts to find one that has no drone. Whats the point. Just go for it and don't look back. Let that engine been heard.

Is the GM Borla the S type ? thx

 

I believe it is a Touring muffler...at least it responds as a Touring would...not as loud as a Sport.

"BVONSCOTT",

I know exactly what you mean about the sound of a GM small block. I race dirt modified cars and absolutely love the sound of my GM 350 (358) engine. I wish I could have my trucks both sound like my race car. Long tube headers with short Borla mufflers, great sound! Nothing beats the sound after that engine starts. The dirt big blocks are even better but I can't afford one of those, a $20,000 engine is not in my hobby/toys budget.

 

This "droan" people complain about is basically terrible echoing inside the cab and you can't hear anything but that sound, it's terrible. It's not really the actual exhaust sound you are hearing, it's just a terrible annoying "droan". The exhaust on the outside of the truck sounds the same all the time, that's not what you hear in the cab with this issue.

 

Some exhaust systems do it and some don't. You can have a good, strong rumbling exhaust without the droan. Both my truck exhausts sound good, Borla & MBRP and neither produce that aweful droan inside the cab.

 

The best example I can give you is it sounds like one of those little Honda Civics that you see with the giant muffler and the 8" tailpipe! They way those things sound, it's like that inside the truck cab, horrible!

      With large equipment or deep mud it is more of a use the higher gear to avoid spinning tires, getting stuck because of spinning tires and doing damage to your machine. The idea is if you run out of torque before you spin tires you can still downshift for more torque. If you are just spinning your tires in the lowest available gear you are stuck and things break.   Automatic transmissions, traction control and electronic transfer cases change the calculation a little as you the driver have less control over each piece.

      My First Project and GMC has me stumped

      By davester · Posted

      are there any codes? with lots of rust, perhaps disconnect/clean both sides of the connection/examine cable ends (the wires) for corrosion going into the sheath & replace if necessary/reconnect ALL the power AND ground cables between the battery, engine, frame, cab, fuse box and starter charm.li (website) has a no-start diagnostic procedure you can work through to get it working.

      OCI, not when but why?

      By Chuck FB · Posted

      Its no wonder you've gravitated to the oil types and brands you have in later years after trying certain brands and one being a specialty oil or at least very hard to come by up here and the other would have been a commonly found oil of the era and the vastly different outcomes as a result to using the vehicles in question the same distance for an OCI . It shows what marketing hype can do without actually having the product to back up the claims and that is no different now with the insane claims that are written on the side of a bottle of oil from some of the off the shelf oils.    What has surprised me and I was already finding this out before I bought my truck with the GDI engine, that this newer fancy technology that seemingly would suggest better fuel economy/emissions with this high pressure spray of fuel is not in reality kind at all to the engine or at least the oils life. Yet they insist on claiming long OCI with this technology just like they did with the port or similar type fuel injection systems when in reality its a step back in oil life to have a GDI system.    I think the mistake your making Grumpy is that your not sending your samples to Blackstone and getting the feel good glowing report that you can run it another 1000 or more miles and then send another sample where they say run it yet another 1000 miles and on and on it goes until your sending in something that looks a lot like road tar and then they may suggest you change your oil within the next 1000 miles 😆

      I am guessing that engines of that design back then had a better ability to be abused and survive longer than a new design engine with the long timing chain and the overhead cams and phasers etc. But I would never guess that an engine could go that far and not fail spectacularly or at least die a slow death.
