AC Cobra exhaust noise and fumes

[CSX3183]

I really can't add much to the majority of comments, without geeting rude.

You are in the wrong hobby, have no idea what you're doing, and frankly, you sound like a government experiment that went bad!

For the fumes getting a tune will probably do the trick or go to fuel injection. I am thinking of doing a dual system . An electric cutout just past the muffler in the side pipe that would go to a turbo muffler and exit out the back. Nice and quite when I want it or to draw less attention from the boy's in blue and at the flip of a switch ROCK AND ROLL BABY. Now if I can just work it out???

Yeeesh, poor Jimmy...I don't imagine he expected this kind of response when he posted his question. Wonder if he'll ever be back.

But it also sounds to me as though Jimmy bought the wrong car. He might've been much happier had he bought one with undercar exhaust and a more modern powerplant, such as a Coyote 5.0-litre. Buying one with a Ford Racing 392 and side pipes, then converting it to what he should've bought in the first place, sounds like a lot of effort and moolah.

Not sure how he could've bought one without realizing it was loud and smelly. Heck, my Cobra doesn't even have to be running to smell like gas fumes. Just opening the garage door is enough to release a heady aroma. But the difference is, I wouldn't have it any other way.

i hope he comes back.....we are all just having our fun, at his expense of course, there are times when i putt by a 80 year old woman that i am rather taken back by blowing her off the sidewalk beside me. but i figure thats life....
jimmy should embrace his sidepipes and realize how much fun he can have by driving down a residential street with cars parked and set off every single car alarm as he goes by......

I have a 1975 ford pinto. It is just to quiet and slow, any suggestions..

[Varmit]

Hell, I just got my sidepipes back from making them louder and removing some back pressure. Iffin it ain't howling, it ain't prowlin!!!!! Love the loudness of it. Pick up some fumes at traffic lights but it is not overbearing. To each and everyone their own, You may want to consider running the pipes under the car and out the back roadster style. Kind of like cutting your dogs balls off I guess!!

I bought the car because it was scary - Noisy - And irritated my neighbours when I start it 24h00 at Night. Why? They party loud through the night at least twice a week with loud booming noises coming from the neighbours man cave. I'm also an old rocker but when you listen to Thunderstruck for the 6th time the same evening at that time its just about enough. I then go out and start the Cobra, which is actually parked right next to the Man cave with only a garden wall between us, and give it 2 good revs. They get the message - the music quits down and I can go back to sleep - Simple isn't it? So there is more to the car than just driving it - Which bring me to the question: How will Jimmy shut his neighbours up?

Jimmy,

I hope you have a sense of humor. These guys have been pretty rough, but that goes with the car. And if you think these guys are bad, just try posting something on the Viper forum!

I got a little tired of smelling like gas fumes when I drive the Cobra to the office and tired of burning up too much $5/Gal gas. So, I bought a Wide Band A/F gauge and sensor like this: PLX DM-6 Multi Gauge Display + Wideband O2 Air Fuel Ratio SM-AFR2 Combo Kit | eBay.

The neat thing about the Holley carb is that you can tune the primary for economy and the secondary for power. You can have your cake and eat it whenever you want. My goal was to get close to 14.7 at idle and cruise and down to 12.5 for power. There is a lot of excellent carb tuning information on the Internet. I bought a few squirters, cams and jets and changed one thing at a time until I got very close to my goal. The final step was to replace the old greasy K&N air filter with a new one. I now smell much better and waste a lot less fuel.

Yep, who in their right mind.....

[RodKnock]

First, there's always the choice of a Corvette. I hear the Z06's are pretty fast.

Second, you could install one of these under the hood for power instead of the Ford 392:

[RodKnock]

And I shouldn't neglect your 3rd option, which I highly recommend. And that is, keep in the garage and don't drive it. You'll certainly avoid any fumes and the noise reduction is phenomenal.

[CBattaglia]

I love the smell and really love the sound. I even love how the car makes my garage smell.

Come to think of it, is there a way to make my car smellier

Rub some 90wt gear lube under the carpets and maybe a little ATF behind the seats and then tell us how you like it.

Prior to driving your car, eat beans. Possibly a quieter form of power for the OP's Cobra too, depending on genetics.

Mongo just pawn.....in game of life.

Hey Jimmy, Kinda like everyone else has said, practally all Cobras are smelly at idle and will burn your eyes while running in your garage (with the door open of course). It's normal. Even if you could fit Catalytic converters on you car, they wouldn't quiet it down whatsoever. Cats are an emision devive, not a muffler.

[kayakjack]

Personally, I like my air with a little bite to it.

[sspano01]

that cobra sounds like it is totally screwed up. i will take it off your hands for $1200

[MRGEORGE077]

Re-engineer your exhaust system so it goes under the car and out the back, end of your problem

Piet, what year is it in South Africa?
