Nice sounding is kinda deep
 

Nice sounding is kinda deep but not enough to hear from inside another car as anything more than just hmmm.

I'm thinking sorta like a diesel, :p

Re: Nice sounding is kinda deep
 

I've heard that the RS-R ExMag is a good choice -- slightly louder than stock. I had a Greddy Evo on my '99 Si and it was a bit louder than I liked, but the sound quality was deep and mellow. As far as air resistance goes, I'm told that the Dynomax muffler allows more flow and sound deadening.

Bunger -- this has been a tough discussion that's been going on for a while. That's cool that you're willing to test some piping -- maybe we can get somewhere on this. It's complicated, but I think we can tackle it...

not sure about latter crx's
 

not sure about latter crx's but my '85 crx-hf has a full stock exaust on it, came from honda welded as one piece, 9 feet long, bolts under the oil pan, and goes all the way back to the exaust pipe tipe, suposedly has a life time warenty on it as well, anyway, it's a small pipe, a few steps in it I think making it smaller as it goes back, and I personaly think it's to loud, because it sounds like what I think you are basicly looking for, rummbly a little corse, but it's fully stock so I suspect it's about as quite as I'll get, if you want it a little louder I supose drilling a few small holes in the muffler.
As far as I can tell what has been said about small pipe and exaust gas volisity is true, to big a pipe and it's like blowing in to a sewwer pipe, you loose all your momentum, and after market headers, altho they alow a smoother flow, they are simply to big for proper flow.

Anyone here know vector
 

Anyone here know vector calculus? If so, good stuff might happen, if not, we'll just have to wait for me to pick a little bit of it up.

Re: Anyone here know vector
 

Well crap, how long is that going to take? Sheesh, my exhaust might fall off in the meantime ;-) Geez, calm down, I'm JK.

Actually I was thinking about Vectors during the airspeed indicator thread. Since most of the time the wind isn't going to be entirely coming from the front or the back, it would attack the vehicle at a vector angle -- suggesting that FE decreases during crosswinds (since the side of the car was mentioned to not be very aerodynamic). But depending on the speed, the crosswind may hit the car at a vector angle that hits an aerodyamic piece, like the bumper, but still forces the vehicle laterally. Anyways, I gave up on Calc/Physics long ago, so we're all counting on you!

Well, vector calculus is a
 

Well, vector calculus is a little different than that. It uses gradients and what not to split up things like flow into the seperate dimensions and find speed and concentration and forces and ****. Good for magnetism I think. I've only had one class on it so far so I dunno, I just finished gradients.

Anyway, we might need to have 3 airspeed indicators and do lots of quick mental math, or get three that are electronic and build a controller, *shrug*

Not saying I'm great at it, but I'm familiar with vector calculus of multiple variables (although more than three variables can be tough **** to do by hand). MATLAB is very capable of handling this though.

Aren't you still in HS SVO? What high school level class is teaching vector calculus? We didn't cover it until the second year calc class @ GT, and it's one of the top engineering schools in the USA.

Can I run this **** in mathematica? It would give me a reason to try the trial version. Can't wait to get it when I go off to dartmouth.

Yep, I'm in high school. I am taking multivariable and discrete math now (two courses) and my multivariable teacher (who also went to dartmouth) has been teaching us vector calculus since we just finished doing multiple integrals. I'm trying to get in a solid foundation because I'm trying to skip the intro math **** and take multivariable the first trimester, which is what my teacher did.

Re: Quote:MATLAB is very capable
 

I don't know if you can run MATLAB in mathematica. I've never used that program.

Damn, I guess that's what I get for going to the lowest scoring high school in one of the lowest scoring counties in one of the lowest scoring states. Good luck with your college adventures. :)

I meant the math shit in
 

I meant the math **** in mathematica, it's like matlab but better.

Thanks for the luck. There never was a math class for me and my 4 friends, but we skipped two years and forced the school to make it. Only 3 of us in each class and I'm the only that is doubling up. :)
