Dual exhausts? everywhere, but not on the right cars

As for cars that didn't have them but should, the only one that immediately comes to mind was the LS1 powered Holden Monaro/Vauxhall VX-R/Pontiac GTO.

GM has a history of getting this wrong. The F-bodies (Camaro/Firebird) had Y-pipes combining both sides into a single exhaust, and then fake dual exhausts on the back splitting back out to two. Not to mention the lazy hump in the passenger foot well for the catalytic converter. That's one thing Ford's always gotten right with the Mustang, true duals.

F you GM

And those aren't the stock tips.

Lolwut, I have a civic of that type and my exhausts don't do that. They go straight out the back through those triangular fittings. The pipes also look like they take a different path to each other as they exit the cat box, even though everything looks symmetrical down there.

Just a thought though, that might be a diesel civic. I know a lot of diesel cars have their exhausts turned down ward. Not sure why, probably to do with avoiding the diesel soot from staining the body work and firing it into the Tarmac instead, keeping it low on the ground and not in the air.

I've got a feeling that it is, and I think that's the exact reason it's done. Kudos to Honda for putting the effort in to fit a functioning rear-facing exhaust though instead of making a dummy. Bet owners aren't so pleased with the extra cost of the pipe though.

I do like a good dual exhaust for balance, regardless of whether or not the car needs it. Must be connected though, dummy exhausts are not allowed in my book. I'm also a fan of the single skinny exhaust though a la Fiesta/Escort Mk1 and lots of BL cars.

For a Mercedes perspective, they have been avoiding this trend until pretty recently. Actually they've gone as far as making single sided twintip exhausts on high powered V8 models and their flagships.

This is the third-newest CLK, apparently a 2003 to be precise.

All the old performance cars like 500s, 560s, 600s and so on ran single-sided exhausts. Really they were duals underneat it all. Keeping with that tradition I had the Magnaflow exhaust on mine built to be single sided dualtip, just a more modern reinterpretation.

In "Ye Olde" top tier models, the most outrageous stock exhaust tips I can name offhand are the 300SEL 6.3

And the AMG Hammer, if you can call it stock, which you can't, since AMG wasn't exactly Mercedes at the time.

These days, dual exhausts come with at least 3XX engined models and up. If you get the AMG bodykit I guess you can have dual exhausts in like a 200 engine or the small diesels. Without the AMG package, the small engined cars usually have the exhaust tips hidden completely.

That's fantastic!
 
I believe that on the F40 the middle 'exhaust' is actually the wastegate for the turbos..
On the 458 Italia however, it's just for show.
 
I'd need to look at the rest of the exhaust system, but the Jag quad may follow the same logic as the six banger (each set of three cylinders gets it own exhaust).
 
That "fantail" is found only on V-12 E-types; notice the badge on the hatch. Straight-six E-types got a dual exhaust like the ones on your XJ6.
 
I was thinking about getting a non-true-dual racing beat muffler for my miata, i think it looks quite nice. I dont expect it to deliver more power than the single version, what do you guys think?

Oh, and the previlance of these on cars? In my opinion Blame Lancia for inventing the unibody and Colin chapman for popularizing it. The unibody chassis configuration might be the worst thing to happen to cars since the invention of the airbag. Often there simply isnt room to package 2 pipes running down the side of the car without compromising something else people want, like bracing or fuel lines.

What. the. fuck. Y'know what, never mind, I'll just remind myself who said it and move on.
 
Bah, rear exhausts are lame:

Love my true duals even if some people think I ruined my car with them... Symmetry is important.

No no wait hold on! Hear me out: Aside from me bringing it up because of the difficulty i in packaging true duals in a modern body, the stated reason for the unibody being a better option is weight reduction. Instead of the body being mounted to a frame, the body is a stressed componant. Thats all well and good, but weight reduction hardly factors in to car design anymore (satnav, heated power seats, 27 airbags, the list goes on...) and i think its a clear direction change by automakers in the last 30 years to build cars that only last a little while before needing to be replaced.

Why would the automaker make a car thats functions are seperated and compartmentalized (bad body? Get a new one, bad frame? Get a new one!) when the very structure of a car can be irreperably damaged by a minor accident, or by simple rust and weathering? They want you to drive your car for 5 years, rear end someone, and have your insurance company cut them a check for a brand new model because your old car will never drive right again.

In a world of 5000lb plus family transportation, a body-on-frame design starts to make a little bit of sense again from a durability and resiliance standpoint. Better?

And if these cars still had body-on-frame construction, they'd be even heavier. Just because people have temporarily given up on light weight doesn't mean it's pointless. Other advantages of unibody are fewer parts, so it's faster and easier to manufacture, and increased torsional stiffness, which makes for better and safer handling. And there's these things called paint and bumpers that protect the body from being rusted or corroded; plenty of unibody cars will last 10+ years even in the salt belt that's the northeast. This is on top of the fact that unibodies are inherently safer than body on frame designs, and that the health care costs of a bad accident can far outstrip any car repair costs. Save $2,000 in the building of a car and its post-crash repair costs and lose far more in gas mileage drop due to weight, increased accident likelihood due to bad handling, and medical bills for said crash.

To summarize: body on frame is heavy, floppy, and unsafe. Like the solid axle, it's effectively obsolete in mainstream and sports cars.

You say 10+ years like thats good enough. I want cars that last 60-100 years or more. There is no reason with proper maintanance your car shouldnt be able to outlive you. There are plenty of 60 year old BOF cars, im sure after that long on the road , i suspect after that amount of time many unibodies would be hopelessly floppy and damaged by weather and debris. (nobody post a picture of an old hudson or Nash ;) )

Outside of budget drag racing and towing applications the solid axle is dead, i dont want to be seen defending it. If this goes on much longer ill make a frame thread so this one isnt derailed. And none of you mentioned if the faux-duals on the miata is dumb or not

Show me 10 60+ year old cars that are used regularly, even in the winter, and are still running just fine and haven't had every part replaced. Go!

10 cars with proof of their driving habits? Im afraid im far too lazy for that.If you want proof, go to the automotve insanity forum on somethingawful.com or go to cardomain and search by year. Personally i think "could be used every day and have had a lot of the car replaced" is more than fair. Being able to replace large damaged portions of the vehicle was sort of the crux of my argument... Most of those cars dont even have oil filters, dude.

Do you think in 40 years there will really be as many Good condition, driving examples of the Geo Prizms on the road as their are 30s and 40s ford coupes today? (both very practical, popular and reliable cars in their day)
