Washer Mod

Thanks. Pick either side. Blacked out or Subaru style. But on topic, why exhaust leak is dangerous and I think it's stupid to do it just to sound better:

Can an exhaust leak affect a car's performance?

"No, but it can kill the occupants of the car.

There is a good reason why tailpipes terminate past the rear bumper. Exhaust fumes can be sucked into the car by the partial vacuum created by the vehicle passing through the airstream. No car is completely sealed from the outside and that is why the trunk on a car has a double sealed rubber weatherstrip."

I would agree with you about the exhaust leak being bad if you were running HFC's or test pipes. But I believe the people who are doing the washer mod all have stock catalytic converters. All modern catalytic converters (our 370Z is a LEVII-ULEV cars which emit < 1.7 grams of CO/mile) convert carbon monoxide to carbon dioxide so efficiently that it will not kill you while driving if a portion of the fumes were to leak into the car. There have been a significant drop in carbon monoxide suicides from car fumes because of the more efficient cats.

People are not stupid for doing the washer mod on here. Just don't do it with HFC's, and especially not with test pipes.

I like how you think!

I've had this mod for over a year and still kickin' haha
I did it purely for sound and modding the car really is the least of my priorities right now.

So after weeks of looking at/listening to different exhaust clips I decided to see if anyone tried removing the muffler. I knew the forums wouldn't let me down! I was surprised how good it sounded in the videos. So I figured I had a half hour to kill on a Saturday why not try it out for myself...
What started as a stupid thing to do on a boring weekend turned into a mission. I have only had the car for 8 months and 2/4 nuts may as well have been welded in place. Nearly a month later and 2 exhaust nuts cut off I finally got the pipes apart.
I agree with all the naysayers on here that a real catback is the way to go, but for $1500 cheaper this produces a pretty b*tchin sound.
Cold start is very loud and there is absolutely no rasp. No drone either, cruising at 2500 rpm is nearly silent. Driving around is almost reminiscent of a V8 - it's that deep.
If you're bored one weekend and have deep 14mm sockets and a breaker bar handy (may as well hit it with some PB Blaster too) give it a try. Just take my advice and stop if you start stripping the bolts!

I think you should talk to the muscle car guys here in my town, not me. They run open headers or long tube headers that dumps right under the drivers seat.
A little thing called atmospheric diffusion is keeping me alive.
Anyways, what's more dangerous. Washer mod or removing your catalytic converters? What if you get rid of your cats and you sit in traffic and the wind carries the exhaust fumes into your car? I'd rather be stuck with the washer mod.
