Is it a bad idea to straight pipe a stock r33 GTR ? What mods i should add to the engine before i do that ?
Those Fujitsubo titanium exhausts are great. They look amazing and flow really well too for how quiet they are. A friend of mine made 390wkw with one and the car sounds stock on idleI took my HKS off and went with a silent Fujitsubo titanium. Has the muffler mid way and the rear can. Super quiet and I love it. I can pull the car out as early or late and not bother anyone.
If you really want something to make some noise but not piss off the neighbors add a cutout somewhere before the muffler. You can have your fun and not get evicted from your 'hood. If you have a test pipe that's a perfect spot. A cutout with a turn down and done.
You really think one car will make that big of an impact on a huge rock's atmosphere? I swear, the weed laws in Commiefornia probably fried people's brains more than a straight piped car.Yeah, it's a bad idea. The exhaust will damage lungs, trigger asthma attacks, and is carcinogenic as well. Loud exhausts are also extremely obnoxious and really just a cry for negative attention. On top of that a stock RB26 has pretty poor boost control so you will probably cause boost overshoot with a straight pipe which can damage the turbos from overspeed.
Where did I say that? The point isn't about emissions at a global scale, the point is that this is something you're doing to people behind you in traffic and random pedestrians that happen to be near you. Anyone that happens to work on your car is also forced to breathe in a high concentration of the stuff. A warmed up car with a properly functioning catalytic converter has zero detectable smell unless idling in a garage. A decatted car emits enough NOx and unburned hydrocarbons to be immediately obvious to people driving behind you, even with the windows closed and HVAC set to recirculate. For pedestrians the smell is not only immediately obvious, it sticks around without wind to carry it away.You really think one car will make that big of an impact on a huge rock's atmosphere?

What are you even talking about? There are huge deals made about smoking in many places. Indoor smoking is banned in many areas. Vaping is less of an issue, but that's because it's not burning anything. Even vaping is banned in many indoor areas.They will probably smell it for a few seconds. You're making it sound like they'll be traumatized from a little bit of petrol fumes. I don't really care if they don't like the smell. How come nobody makes a big deal out of fumes from vapes, cigarettes, and weed? But a few seconds of sniffing some fumes from a car that they will probably not see again is a catastrophe. I've sniffed so many petrol products and fumes in my life, and my lungs are fine and I am alive. It's just an excuse to feel "offended" and "violated" because someone decided to have fun by removing their catalytic converters.
Are you in Northern California or something? That is the only place I can think of that makes a big deal about smoking cigarettes, yet they allow marijauna users outside to smoke with their atrocious smelling substances.
Josh, you actually believe that people in an insulated building can smell a straight piped car's exhaust fumes? How come I never witnessed myself huffing fumes when I lived in the South with no emission standards and boys pulling up with straight piped American muscle cars, yet I never smelt the fumes in an insulated building? Even my neighbor who had a straight piped Z28 didn't smell for me, even though he was next door. It's just an excuse. They're stupid loud, but the risks you're talking about are overblown like the msm tries to push. If op lived in America, he could just weld a hollow cat onto the straightpipe. Why is everyone in California so obsessed with those catalytic converters? It's funny, that even the Donut media tried to push false narratives of how cats are supposedly good.
This is a really weak rebuttal. Smoking a cigarette outside barely compares to a gasoline engine decatted because just going down the street an engine is ingesting a lot more air and creating a lot more exhaust. Indoor smoking is a much bigger issue because it's concentrated.You just proved my point with the mask. There is still smoking in public places outside. And people still do smoke out in bars, despite that map you provided.
I never said cats don't do anything. Regarding scent, you must have the sense of smell of a tyrannosaurus-rex then. Even at races I go to my friends and I cannot really smell the scent of the petrol being burned and expelled. I strongly believe you're just trying too hard to prove that a catalytic converter is such a good thing for a car. It chokes the car, reduces power, and in turn you only get happy cyclists, Karens, and city dwellers. And I still cannot believe that you can smell a car's exhaust from a building, if windows are open and the car is 8 feet away yes, but if you're in an office building working from a cubicle I highly doubt it. If John wants to straight pipe his car, I don't see the big deal. I'd just keep the muffler on to make it less loud. It's not like his 1 car without a cat will destroy glaciers, kill people, etc. Let the lemmings drive boring eco cars, enjoy life. And please don't tell me you actually believe man-made climate change is real.
It's pretty bad on the outside...
I barely ever smell anything inside the car but people behind and outside DO . You definately dont want a cop car anywhere near you and Ive had some people at stoplights pinch their nose and point at my car.
All I know is that I rode behind my buddy's WRX after we put a full catless exhaust on and it was awful - I had to change lanes to try to escape the smell.
If you have ever been at the race track with all the high performance cars zooming by, the rancid gasoline/exhaust smell is pretty much what it smells like.
Catalytic converters are there for a reason. It's not the 70s anymore, catalytic converters can flow as much power as you want them to. Their restriction is negligible when properly sized, the more power you want to make the bigger the catalytic converter you need:With no cats it smells like some *******'s ratted out 1988 Monte Carlo.
