Uh, I doubt it... It's a Porsche not an F150. I would be interested to hear what it sounds like if you do it though.

When people risk their lives, shouldn't it be for something very important?
Well, it better be.
But what is so important about driving faster than anyone else?
Lots of people go through life doing things badly. Racing's important to men who do it well.
When you're racing, it's life. Anything that happens before or after is just waiting.

F150

F150???

Check out Fabspeed's clip of the non muffled 2004 GT3....it doesn't get any more Pure Porschefile than that. Sounds just so awesome.

You should check out the sound on the 997S with the muffler bypass pipes. Sounds even sweeter. They make the bypass pipes for the 2nd cat for the 986, but seems like no one in this forum have tried it.

I'm guessing that you'd lose some low end power because you need backpressure for low end torque.

Hey Jeph, yeah I love this forum. A lot of good threads. A lot incomplete. But mainly its because I'm up in the Northeast, the roads are icy and sloppy with snow. Although it is supposed to warm up this week! And its busy season for me so I'm in the office a lot on wknds and nights. Cabin fever.

2000 S with no muffler. Very loud when you step on it and resonance is horrible at 2000 to 2700 rpm. If all I did was drive it once in a while around town and at the track, I'd keep it this way. Using it for a commute car and doing any long distance freeway driving is rapidly becoming impossible to live with.

Personally, I find cars (of any type) with the overly loud tailpipe action to be obnoxious. A porsche is a racer, but it is also classy car, not a hoopty. All that look a me noise is for children that have no respect for their neighbors.

First off, it is illegal and likely to get you a nasty ticket in most parts.

Moreover, if it was my neighbor's car, I woud have him arrested.


Otherwise, I am sure it is fine!

Which communist state do you live in? It most certainly is not illegal. I've been pulled over for not having the current tags on my license plate and the officer complimented me on my car's sound.

With the 4 cats, the noise isn't too loud at idle and with light throttle.It's only when you step on it or drone along at 2300-2700 rpm that the dBA's go way up.

I guarantee you if you drive a Box with no muffler in CA you will be ticketed and your car will be inpounded. I can lead you to the CHP guys who will be happy to perform this task.

Nice try. I live in CA and drive all over the state.

ETA: The officer was a CHP.

You can stow the attitude here bub. I also live in CA and if you are driving in this state with no cats and no muffler, you are at risk to be cited and have you car impounded. That is simply the law.

The fact that it hasn't happened to you yet simply proves you are lucky, not correct in your assessment.

"The catalytic converter plays a major role in the emissions reduction of a motor vehicle. The vehicle manufacturer has matched a specific catalytic converter to the vehicle to minimize emissions output. Both CARB and the EPA do not allow the replacement of a catalytic converter with non-exempt "high flow" performance replacement unit. In fact, it is technically not legal to even replace a converter unless it has been proven by technician to have failed, and then it can only be replaced with an exempt OEM equivalent unit."

Hi,

I agree with Brucelee 100% on this. These are afterall Street Cars - don't try to make it everything. Get a dedicated Track Car and have at it. If you can't afford this, then too bad, leave the Cats in place.

The Greens are already trying to zero-in on Enthusiasts as creating more pollution and wasting Dino Juice - we don't need people like you giving them more ammunition...

Happy Motoring!... Jim'99

Yeah and just screaming give me a ticket. Of course if they would help us all out and just start ticketing those Honda's and Neon's with exhausts so loud it puts a Harley to shame we would all be better off.

Actually, here in CA, they are targeting these wonkers using the Smog regulations as the legal angle. Seems it is easier to ticket them and tow their cars for smog violations than it is to catch them speeding and/or endangering our lives on the freeways.

I am fine about it. They are a menace, nothing more!

Who said anything about no cats? I've got all 4. You're the one with the attitude BTW.
