Here's why no DUAL Exhaust for the Sedan
 

There have been several questions about why no dual exhaust
for the sedan.

FWIW....
The pic shows why....
On the right side; where a second muffler would go;
Infiniti chose to locate the fuel vapour recovery canister.

Also the spare tire wheel well is several inches off center to the right.
So the canister space on the right is smaller than the muffler space on the left

Yea, but it's just stupid that the 3.5 Altima, Maxima, Z, and G coupe all have dual exhausts except for the sedan. Even my bro's Acura TSX has dual exhausts.

Infiniti should remedy this for the next body G.

I agree completely.
The reason for the pic was that I was investigating the posibility of relocating the evap components.

It's a no go
Nowhere else to move them to. :(

Yea dude, I was away ahead of you on that one, not possible. I took it to 2 different exhaust guys, a big negative.

This is my biggest complaint with the G35. It just seems crazy that you cannot put a dual exhaust on the G but I guess that's how it is. I almost want to put a fake tube just for the look but that would be lame.

can we relocate that?

We don't need to be like everyone else. We are unique.

The G35 sedan did in fact have a dual exhaust setup prior to the final product. Take a look. This is a G35 sedan, note the large exhaust resonator, the narrow tires, and spare tire well. The picture was taken from the 1/03 issue of Motor Trend.

I have dual exhaust. :p

That's what I was looking at when I took the pin.
It's just too dam big, plus fuel evap lines test solonoid etc.... :(

I've seen that b4....one of the reasons I started looking.
That was pre production, probably b4 emmission issues were sorted out

I think once they got to production they had to find a place for the evap canister, & the dual got tossed.

The other strange thing that doesn't make sense, is why the spare tire wheel well is shifted off center.
You can see this in the MT mag pic

What's the big deal about two pipes at the rear? Before American tastes for "duals", most European cars had one exhaust, usually with a large pipe. The duals create more weight. Our cars make 280HP or more with one sided exhaust. The photo above shows you can have real "duals" while keeping the factory style, if performance is your true aim. Most of the cars with separate pipes are front drivers. More room without the axle. I don't get it.

Half the cars that have dual exhaust don't sound nearly as sweet as our sedan, nor do they have the performance edge.

Personally, I like the twin-tips. Everybody and their ricer brother has split exhaust pipes, true duals or not. I like that we're different.

I completely agree. I used to work in a muffler shop that my dad owned for 10 yrs, and I always hated the fact that someone would bring in something that was NOT supposed to have duels and have us put something there, it always looked worse than what was there originally. If you look at the setup of the duel exhaust on the coupe, Z or most other cars with duels, it's purely just for looks and not much functionality, a true duel exhaust has one tube per side all the way from engine to back of car. If you want the performance of the duel I would get what skeleton_cru has on his car, that at least is closer to a true duel exhaust. But to put another 50lb muffler on the car and say it has duels, I would rather save the weight, this is why the sedan is faster than the coupe (here come the flames) :D

i wouldn't say faster... but you kept it pretty factual. what most people don't realize is that the 350z nor the g35 coupe have dual exhausts. they have dual muffler tips. that's about all. i'd prefer our setup for the same reasons nissan did. do we need more airflow? i'd say not. not for an n/a setup. then why the two pipes? what's really the concern? looks? this used to bother me too. but performance is way too good to care anymore.
