Home- made EXHAUST SYSTEM ideas??? (no muffler, no cats)

[supradjza80]

I guess most of you haven't ran a straight pipe on a turbo car (not some 1000hp car, just a normal street mk3)...My car is no louder than a stock SRT-4 which also has a mufflerless exhaust straight from the factory...I wonder how they pulled that off maybe because the turbo muffles the exhaust note.

 

[supradjza80]

also if all of you are so worried about a little noise increase than just keep the stock exhaust system on the car. My opinion is a sports car can have a loud exhaust, and a straight pipe on a turbo car is not even that loud. I have heard tons of cars that are louder which have nice expensive exhaust sytems.

heres a video of the car on the dyno, you can compare it to the cars that go in front of it, my car is the red one at the end

Calm down Figgie, just calm down man. It'll be ok. I know enough fluid dynamics that the guy who coined the word back pressure needs to be curb stomped.

It's ok dude... pressure is defined as resistance to flow... no one needs to die, put down the intellectual beat stick!

I was merely pointing out that the whole "exhaust backpressure" thing is archiac thinking and complete BS. As for back resistance, I'm afraid I don't know enough about electronics to even begin to play games like that with you, figgie. I know several electricians... I call them when I have electrical issues, so that I don't fuck it up worse.

Sometimes I wonder if you lose sleep over SM threads like this. Staring at the ceiling saying "WHY CAN'T THEY JUST UNDERSTAND!"

I think this thread is discussing the merits of running straight pipe exhaust, rather than the idiocracy of "exhaust backpressure"

lol lol lol

dude you made me laugh at loud at work here

I do not lose sleep for anything, hence my absence on the weekends and night time Well at least you know what I am talking about. One person!

btw

there is no such thing as "back" resistance in electronics. But it does sound silly, don't you think

psst

The Toyota Supra is A Grand Touring car not a "sports car" .

Just thought I clarify.

i thought it did because i have this little button on my S-NES controller that said turbo. so i figured the circuits might be more free flowing. lol:naughty::biglaugh:

ed.d.

WAIT....

Stock downpipe and a straight pipe? :rofl: The downpipe is the biggest restriction in the system given it has a cat in it that clogs way before the second cat will.

I already said my piece on straight pipes, and most sports cars are NOT that loud as they use tuned exhausts...

In short, backpressure in the exhaust is a heaping pile of bullshit.

If you're running the car on the street, put a REAL exhaust system on it that meets the legal requirements to be insured and tagged in your area.

If I heard a MkIII Supra rip out my ear drums just by accellerating from a stop light, I would go home and sell mine in order to avoid being associated with that douchebaggery. Is it really neccessary to make that much noise to get to 20km/hr? I've seen (heard) civics, tiberons, neons, sunfires, and alot of other rice, that are louder at idle than my 7M is at WOT... wtf? Get a real muffler assmunch.

Let me translate the sound of a fartcan/lack of muffler, pulling away at a stop light, for you:

IIIIIIIIIIIIIIIMMMMMMMMMMMMMMGGGGAAAAAAAAAAAAYYYYYYYYYYYYYYYYYYYYY

If it's a track only car, by all means bang away without any exhaust. If you're going to street it, do us all a favour and get a real exhaust system.

/rant

ok- lets get stuff clear, 1st, i meant resistance not back pressure, yes, the setup will be for track only (im not going to spend gobs on new shit just for like 1 day out of the week), secondly, im wayyy shure (by your attitude) on a god damn toyota supra forum: assmunch, you scream IIIIIIIIIIIIIIIMMMMMMMMMMMMMMGGGGAAAAAAAAAAAAYYYYYYYYYYYYYYYYYYYYY on a daily basis; get anger therapy please

 

[Poodles]

Yeah, nice personal attack.

:ban:

I swear we got another dumptruck of stupid this month...

 

[AS_supra]

my old one got custom 4 inch dp with 4 inch straight back to jic exhaust...its loud and back fire pops alot but that only happens at wot!

 

[supradjza80]

so is a DDP a bad choice on a street car? Just wondering because it might get loud sometimes. Yeah maybe everytime you go above 2000 rpm with just about any load on the car. BTW i know the car needs a DP so i hope you have fun laughing...

And as for the supra being a grand touring car, fine call it what you want, it is still toyota's sports car...

I'm done with this thread
