Does the '04 TL have a true dual exhaust?

GoBig

No. It's a single pipe and splits near the rear axle.

Is the exhaust same as the Honda Accord V6?

Bitium

I don't think so, but I'm not sure.

You are talking about dual in a sense of one entire pipe per side (3 cylinders)?

I know the 03 and below does not, but the 04 has the dual CAT's. One of the reasons they are normally together if because both sides have to go through a single cat, not the case for the 04 TL.

But 04 goes to CAT twice. There are two individual CAT near the engine, then they combine together to the underbody CAT. Then they split after that...

I will post four pics, you will know...

Two pipes from Engine+CAT in the bottom of Engine...


I don't know what the true dual exhaust means. Let me know what you think.

Thanks for the feedback

Another...

Also, Acura says,

HIGH-FLOW EXHAUST SYSTEM WITH CLOSE-COUPLED CATALYZERS
To reduce weight and move the engine's two primary catalytic converters as close as possible to the combustion chambers, the TL exhaust manifolds are cast right into the cylinder heads. A 900-cell per-square-inch high efficiency converter mounts directly to the exhaust port of each cylinder head for extremely rapid converter light off after the engine starts. This mounting system has the added benefit of eliminating traditional exhaust header pipes, which saves a total of 17.6 pounds.

To ensure optimum flow and reduce backpressure, a new hydroformed 2-into-1 collector pipe carries spent gases down to a 350 cell-per-inch secondary converter under the passenger cabin.

A new design for the exhaust system downstream of the secondary catalyst, including the dual silencers, further reduces back pressure and is 11 percent lighter than the comparable Type-S arrangement. Because these smaller silencers are easier to package, the rear of the new TL has a more refined appearance, finished by dual trapezoidal exhaust outlets that are tightly integrated into the rear fascia.

In the end, they split...

Another angle...


I obtained those pics from someone complaining his car having bad welding issue.

Wow; great pics. Thanks

Pices312,

Totally off topic, but may I be the first to say that the picture you attached has to be the scariest F&*$@'in thing I've every seen. I'm gonna have nightmares......:wow:

Hey, those photos look familure, 2nd day I had the car as I remember

NSXY

Chill Burr, it looks like a common bottlenose dolphin, probably in San Diego area. We see them surfing all the time here (Del Mar).

rets

Sorry, need4spd, I really cannot remember who is that "someone" providing them... Yes, it's you after I jumped back to do the search, they're your pics... sorry for all the copyright you should have... We're all shocked while seeing those welding stuff.

However, they're very useful...

Next time, We'll send NSXY into the water to find out

need4spd

Rets, no problem it was good to see the bottom and post those photos, everyone got to see the aero panels added.

BTW - J/K, I was not concerned, thats why the

great shots, thanks
