Re: 2015 Limited V6 loses dual exhaust

What some of you don't seem to understand is that, for the most part, packages are set up the way they are because of researched demand. While YOU may not want to buy everything in a package, most do or will.

A la cart vehicle building is extremely expensive process-wise. This is also why most options are not offered individually and piece-by-piece. If you did every option individually, it would make the build process too complex, even more prone to errors, and much more expensive. In addition, most consumers DON'T want to spec out a vehicle on a piece-by-piece basis.

On top of this, imagine the nightmare of dealer inventory ordering if every option is individual. With so many choices you'd be almost guaranteed to get your stock wrong, with a commensurate loss in sales. Remember...a consumer is more likely to accept MORE options, as long as they include their "must have" option or two, rather than a vehicle that is missing an option they feel is necessary.

I disagree with you on this. By your reasoning a dual exhaust with an 'X' pipe would not be a true dual exhaust. My 2015 Altitude V6 has the dual exhaust and I really like the look. Two separate pipes come from the exhaust manifolds into a central muffler, and then out two pipes to the rear. Cars like the Mazda 6 that has one pipe from the exhaust manifolds into a single muffler with dual exits I agree is NOT a true dual exhaust.

I agree though that 95% of people buying a GC couldn't care less about the dual exhaust, let alone realize that it actually has two pipes instead of one out the back.

LOL... that's not a true dual exhaust.

Greetings,

Even through it has 2 pipes exiting the rear is not a true dual exhaust?

Their is only one muffler that excepts engine output from both sides first and mixes the exhaust. The rear muffler/resonator is a secondary system to help further keep the sound down.

A true dual exhaust can either be designed around increase the sound level or to increase engine performance. And that is where it starts to get fun.

Best for now.

Any system running two into anything and back out to two is not a true dual exhaust. True dual exhaust systems more or less disappeared with the advent of unleaded fuel and catalytic converters in the 70's as the cost was prohibitive.

A true dual exhaust runs separate catalytic converters, mufflers and/or resonators for each exhaust bank. You won't find many vehicles running that set up today.

Greetings,

I understand today, that the purist do not consider the H or the more efficient X pipe to be a dual exhaust because the exhaust pulses travel from bank to bank at the transfer point.

Best for now.

I don't consider an H or X pipe to be an issue if there's no restriction and all it's doing is balancing back pressure between exhaust banks. Those were in use (mostly aftermarket) for power gain on true dual exhaust systems before the advent of catalytic converters.

Re: 2015 Limited V6 loses dual exhaust

In general unless you have some pretty wild cams, a NA six does better with a single exhaust since there is no overlap & can do scavenging. OTOH with a V8 you need duals because it needs to be treated as two 4 cyl engines from an exhaust standpoint.

Of course if you just want glitz....

Mine just has the base radio plus A Lot of add-ns via BT. That way I can have the same experience in all of my cars because it goes with me.

ps it does have a USB in the glove box and an aux 12v socket.

Re: 2015 Limited V6 loses dual exhaust

Greetings,

I was speaking to both Borla and Flowmaster about my V6 3.6 dual exhaust upgrade. Both tech's each recommended to stick to a 2.25 pipe to keep the back pressure present. With the CAI in the loop and the V6 3.6 compression ratio, they felt this would give me better performance.

Interesting, Flowmaster recommend to stay with the scavenging via an H-pipe as opposed to exhaust pulses and the X-pipe method. Borda really did want recommend anything further since they have nothing to back up themselves, which is a extremely good policy and being honest. Although he did recommend to do some more searching and should be able find answers.

So my plan is look into a custom made 2.25 system since nobody sells a kit for it.

Best for now.

Re: 2015 Limited V6 loses dual exhaust

Gents - just picked my GC up today. Disappointing about single exhaust. Is there a kit / exhaust upgrade to have a dual exhaust or something like that is not possible?

Disappointed that there was useless extra exhaust piping and weight on the vehicle?

At the OEM levels of hp and torque, there's absolutely no need for a dual exhaust on the V6.

About as useful as dual exhaust on the Chevy 1.4 liter 4cyl engine in the Chevy Cruze.

Pure cosmetic.
