Alpo Posted October 11, 2021 Share Posted October 11, 2021 See the exhaust pipe on that truck. Why? The man's got a pair of 2-inch exhaust pipes back to six or eight inches from the end of the pipe, and then it bulges out to four or five inches in diameter. What is the purpose of this?

Trigger Mike Posted October 11, 2021 Share Posted October 11, 2021 My teenage son said it's the rave now but it really makes it sound horrible.

Waxahachie Kid #17017 L Posted October 11, 2021 Share Posted October 11, 2021 To those of us that were raised in the muscle-car era, this is just a feeble attempt to look cool, and maybe make it sound like it really had some power. We know better. But...having said that, I am glad most of us are still free to do what we want to, to try and make our vehicles look cool, and unique.

Injun Ryder, SASS #36201L Posted October 11, 2021 Share Posted October 11, 2021 Two related stories: 1) Back in the late sixties, a friend had a '65 Mustang with a six cylinder engine. He installed a JC Whitney "dual exhaust" system which consisted of a flexible pipe and two exhausts! 2) A few years ago I saw a Toyota with two PVC pipes on each side just attached to the car, not the exhaust pipe, to make it look like a fancy exhaust system. Wish I had gotten a picture. Link to comment Share on other sites More sharing options...

Pat Riot Posted October 11, 2021 Share Posted October 11, 2021 Isn’t it great that people are free to be goofballs, dipsticks and (pick a descriptor)? I had friends that would do dumb stuff to make their cars appear to be something they weren’t. They had headers and glass packs installed on 6 cylinder engines with 2 barrel carbs and all manner of poor boy mods just to try and look cool. One friend had a 74 Plymouth Duster that had a 318 engine with an automatic transmission, but he tried to drive it and make it sound like he was shifting gears with a stick shift. He installed a Cyclone muffler on it with the factory manifolds just to make noise. The boy wasn’t wrapped real tight. He stopped doing his little shiftie maneuver when he messed up he transmission and had to pay several hundred bucks for repairs. Link to comment Share on other sites More sharing options...

When I heard about it right after it happened, my first thought was, "Please don't let her be from Alabama." Thanks Minnesota for making us look good. I figure the loud mufflers on trucks is like the jacked up 4x4's that never see dirt roads- much less going actually off road. They are trying to compensate for certain things that they are lacking. The one trend I can't stand is the nose up in the air and the tail almost dragging the ground. Not only does it look stupid but the driver can't see anything in front of him.

Smuteye John SASS#24774 Posted October 12, 2021 Share Posted October 12, 2021 What I'm referring to is the top picture. It's usually 4x4's with lift kits- but the added clearance they give is immediately counteracted by the back being down on the axles. That pitches the nose up in the air and the front bumper a couple or 3 feet off the ground. Like this one. The lower picture on your post is just a low rider that happens to be a pick up.

Cyrus Cassidy #45437 Posted October 12, 2021 Share Posted October 12, 2021 1- He is "compensating." 2- With carbureted engines, the theory was that you could reduce "back pressure" (not all of the exhaust escaping due to constrictions in the exhaust system) by making the exhaust larger. With any back pressure, the carburetor cannot push in as much fuel/air mixture, so it reduces power. While this *may* have some ring of truth, I would wager the bulk of back pressure was caused by the valves, not the exhaust pipes. Still, they sold millions of oversized exhaust pipes to hotrodders over the years. That said, IT DOES NOT WORK ON FUEL INJECTED ENGINES, because everything was designed to function correctly as designed. Link to comment Share on other sites More sharing options...
Sgt. C.J. Sabre, SASS #46770 Posted October 13, 2021 Share Posted October 13, 2021 I still don't get the fascination with spinning rims, or 22" wheels leaving about 2" of sidewall. And I'd STILL like to see a custom car show take on a pick up and NOT say "Slam it to the ground". I have no interest in a vehicle that I'd have to rappel down into.

Horsepower can be freed from fuel injected engines through lessening the exhaust restrictions. Engines are rarely design to achieve maximum power.

Alpo Posted October 14, 2021 Author Share Posted October 14, 2021 Regardless of which of you two is right, how is the end of it helping? I could see if he had 6-inch pipes all the way from the exhaust manifold to the end, having less back pressure. But 2-inch pipes most of the way, and then expanding the 6-inch for the last little bit? That's the part I don't get. Is that expansion of the last few inches supposed to do something, or is it just to look cool? And if it is supposed to do something, how? Link to comment Share on other sites More sharing options...

I don't see where he wrote anything regarding your commentary on carburated engines. Seems you're more interested in defending what you wrote than reading for comprehension yourself?

Nose in the air and back way down. A number of years ago I went to Dallas with a friend to pick up 6 rolls of carpet. On the way back we looked like that. My friend mentioned that the steering was really easier than when we were empty. I told him no weight on the front that is why. It was a wonder we made it all the way back to McAlester, OK.

The reason is that the sound basically starts at the end of the exhaust pipe and works its way forward. Large tips give a deeper tone than the pipe in front of them. It may not make a huge difference but it's not zero. In my old age I've learned to like much quieter exhaust, but I still smile when I hear a nice deep gurgle from a V8.
