I was just adding on to Tim's comments yours wasnt there at that time

...we must have been typing at the same time...

 

that's cool . i understand

 

I think you should just get one beefed up exhaust...

 

Here is the thread I believe.

It's such old post the photos were gone.

I would love to do this as well. But I have a few questions. Maybe somebody more up to speed on exhaust theory can help out.

Why do the mufflers need to be at the rear? Or at the least, why would both rear mufflers need to be in the rear?

Specifically, if one were to use a setup like stock, or the stillen/borla with a single rear section on the driver's side, could an outlet be routed to run beneath the car with a curve and tip? I know it wouldn't look symmetrical.

My point is, can this problem be solved with some imaginative piping and use of off-the-shelf components(magnaflow, for example) without having to relocate the evap cannister?

 

I believe that a good muffler guy could come up with a system. I had a local old-timer, who used to build NASCAR racecars fab a system for my Ram pickup. It`s over 4 years old now, never leaked nor rattled. It was a little too loud for my liking from the beginning, but most people like it. Looks good, too. When I drive by, folks look and wonder whose truck that gray-haired old phart is driving!

 

That's right...it was his that I saw! I couldn't freaking find his thread though . He has since converted to the HKS .

 

I like the look of a clean muffler back there.

It seems like the easiest way to do this would be to have a few resonators in line and a mid-muffler like the borla has, then just have straight pipe back to two tips. No bulky muffler back there.

When I do my motor build I am going to need to go up to dual 3" so I will look into something like this at that time. Maybe before if I get anxious.

 

Here's a pic of (TunerDad) dual exhaust...

I don't like it. If he had a rear valance cut to fit them it would look 100X better.

 

Actually years ago when the G35 sedan was first tested by Motor Trend (April 2002 issue?), there was an underside picture of a pre-production sedan that had dual mufflers with single tips (exactly like the 2nd gen sedan setup). The secondary pipe simply exited from the passenger side of midpipe resonator and a muffler was located where the evap canister and plastic cover are currently located. The mufflers looked to be about 70% of the size of the single muffler setup. I was always curious as to where the evap system was located with this setup. I think Nissan decided against this design because:

1) It doesn't add anymore power
2) It's more expensive
3) It added unnecessary weight

I guess for the 2nd gen car, too many people wanted the dual tip look of the coupe along with other well-liked coupe styling cues.

 

I have enough power. I want a second muffler!

 

we dropped my exhaust on the dyno and only gained 10 HP. as much as I like the look of the duals on each side, it is not worth it.....I already dual 2.5s (similar to a borla but with separate mufflers in the back.)

 

On the dyno now or with your TN?
