Removed Stock Muffler...My Thoughts

i don't want to see any more comments about this because:
1) i'm not going to be driving the car around as you see it in the picture
2) it's not louder than cars with test pipes or "loud" systems out there already
i took the car out for a total of about 20 minutes on a single day just to hear what it would sound like

For me.. I really like the sound of the Stock exhasut, but i am always for saving a buck or two on something that isn't rocket science. I have a local exhaust shop here that will fab up anything you want for $60, including pipe (not mufflers). I have hold friends drive in from other states just to get their exhausts done here. Its just a simple guy in a run down shop with a few basic tools and a lot of skill. I could pick up 2 Ebay Farcans for $50 and have a header back true dual put on for $110.00... But again, I really like the sound of the stock exhaust.

i think i will fab up some custom piping as well and remove stock muffler

tell you what, ill buy a real cat back system if i do this and i don't like the way it looks from the back...deal?

what's the zip code down there? kinda far, but maybe worth considering!

It is your car so you can mod it however you feel necessary. I was only stating my opinion. I will chime in once you have completed the work. Good luck

You want to put tailpipes on a 350z? Do you understand the concept of exhaust flows? Unless your pushing a turbo, you dont need that. Your exhaust needs some backpressure. If you want something a bit louder, I suggest running test pipes with stock muffler. You get a great sound, plus you wont get hassled by law enforcement.

the guys right, nomatter how good that sounds, it looks bad on a $30k car man,, break out the plastic and hook yourself up!! I got the apex- n1 for my Z and i love it!! or cant you somehow gut outthe stock muffler?? is that possible,, then just re-hang it,,, might have the same sound.... props for being creative though!

you don't think that test pipes and new high-flowing exhaust system give you less backpressure than stock exhaust minus a muffler?
im open to information...
97supratt: did you ever get newer videos of your evo2? i'm still waiting to hear how that sounds...that last video-the camera made it seem like you werent revving the car
CFaddict: i know that gutting **** does not work too well unless it's done perfectly, as that will create a lot of turbulence in the airflow

Lastly, yes you lose back pressure with test pipes but at least you're not missing your muffler. There is a reason why Nissan made two cut outs and a big gap in the middle of the rear, its for MUFFLER(S).
You will yield more power with test pipes and stock muffler than you will anyway with stock cats and no muffler.
You're thinking more along the lines of V's with no mufflers and they have tailpipes. Well the Q needs a muffler, so if you want to take it off and put tail pipes, I suggest posting pics on some mustang V forum and not this. :icon:

From http://www.sportcompactcarweb.com/te...haust_systems/
"Some self-proclaimed engine gurus claim too large of an exhaust tube on a car can cause problems; engines need a certain amount of backpressure to run correctly. Although the statement about not running too large of a tube is correct, the assumption about engines needing backpressure is not. A vehicle needs the lowest backpressure possible to produce the maximum power by keeping pumping losses low. Too big of an exhaust pipe causes power loss, especially in low-end torque, because a big pipe has less exhaust stream velocity than a smaller pipe. Velocity is essential to get the best scavenging effect from tuned headers. (We will discuss this in more detail later.) In simple terms, if the exhaust gas flow is kept high with good velocity, a vacuum can develop behind the closed exhaust valve allowing even better scavenging when the exhaust valve opens on the next exhaust cycle. Good scavenging is even more critical on valve overlap, the part of the four-stroke cycle where both the intake and exhaust valves are open."
"One thing I do want to explain before I get too far into this is backpressure. I hear "You need backpressure to make torque." all the time. And it even comes from "tuners" as well as customers. This is flat out not true. Before I arrived into the company of true tuners I fell into the same trap myself. The reality is that backpressure is the enemy. You want to keep it as low as possible. What you do want is to keep velocity up. However doing the things that keep velocity high involves slightly more backpressure under some conditions. You want to keep the gasses moving as quickly as possible to make both good torque and top end power. The perfect exhaust system would keep the gasses moving as fast as they did coming out of the cylinder and have zero backpressure. However this is impossible to achieve in the real world."

If we didnt need back pressure then why do N/A cars lose torque if we install 4" exhaust piping? It's not a myth, its a fact. Almost every N/A car needs some sort of back pressure, whether it involves cats, mufflers, or pipe diameter restrictions.
Turbocharged vehicles do not need backpressure because the turbocharger works off the exhaust system.
