exhaust improvement on q

[DAEDALUS]

It could be a fun project. Too bad that last guy didn't follow up with results after all the work he did. I'd like to know more about who's making custom manifolds in NZ for the VH.

Are you refering to the link to another forum? That sounds like a fun/expensive project. Also, any shop with a mandrel bending machine can make custom headers for the VH

[PoorManQ45]

Unrelated, but here's a link that has body kits for the Q45. I think they're a reasonable price compared to most that are made for the Q45.

PoorManQ45,

I have seen a setup like you are describing, a while back, in a hot rod magazine . The guy had exhaust dumps with an electronic valve. Basically, he could open and close the dumps at will from inside the car.

I don't remember if there was any performance gains mentioned in the article. It seemed like the main purpose of this mod was for sound.

If you want to experiment, I say "Go for it."

I have done all kinds of stuff to my car just to test a hypothesis.

Are you going to be doing all the fabricating or is it going to be done by a shop?

I know that other people have modified their exhaust. But, it sounds like they had to spend a little too much money, to me. What have other exhaust modifications cost? $500+? I'm thinking about spending a total of $25~$50 to replace the exhaust.

I have two ideas.

Here's what I would do. First, cut the exhaust off after the headers. Remove the old exhaust system. In it's place, I would weld in pipes of ~3in on each side. The pipes would be about a foot long. They would dump the exhaust gas straight down. Underneath the car. Or, I would take them out behind the front wheels.

Another way I would do it is. I would leave the stock system alone, except for a few things. I would install an electronic bypass valve close to the headers. The valve, when opened, would dump the exhaust straight down. When it's closed, the exhaust would flow/sound stock. I would install a switch close to the drivers seat. I kind of like this idea a little more. It is very stealthy. Could you imagine the look on the guys face next to you. When you pull up next to him, your car sounds nearly silent, very luxurious. When he revs his engine(usually sounds like an angry bee), you flip the switch to open the valve. Then you rev your engine, and out comes a loud obnoxious growl. . This modification would kind of act like nitrous. HP at the push of a button.

What do you guys think of these exhaust mod ideas?

I haven't read this whole thread, but I saw the original question. I have chopped many exhaust systems off of cars(not Q45) and ran them like that just for fun before doing a custom exhaust job. The results all were: sounds like CRAP and seems like is has less power at the bottom end.

I guess it is easier to talk about experimenting on t- birds and mustang just because replacement parts are dirt cheap anyway. With the Q if you have to go back it will hurt your pocket. Maybe that is where the fears stem from.

[1992Q45A]

Or the fact those two cars are rolling POS's that are underengineered from the factory. So some rinky dink mod make may actually help

Not so on A finely engineered car like a Q45. That's the problem with this car being dirt cheap now, chronies are finding their way to them, and thinking they can perform ford like magic on them

Stop doing that. .

Ford is a company just like Nissan. They both spend millions of dollars on research a developement. And if you don't think that ford is the same as Infiniti, then lets compare SVT Ford to Infiniti. Do you think that the SVT Cobra is a POS? I personally think that it is a very nice car. I have nothing against Infiniti either. The Q45 is a great car also. People have stated this exact same thing to me. Now I will say it to you. "Don't go spewing a bunch of crap about something of which you know nothing about."

Id be willing to bet something expensive that infiniti puts more time/money into making a quality product...

There you go, wrestling the pig again Wes!

Just because I like wrestling in the mud with pigs doesnt mean I need to be made look like a fool!!!!!

The larger a company gets the more inclined it is to produce consumer appliances, and less likely is it to build fine automobiles.

Fortunately, Ford and GM (especially GM... and I hope Roger Smith drops dead) have learned a few hard lessons and began putting some personality back into their vehicles.

Put me down for a Cadillac XLR. I'll take delivery after grad school.

[elwesso]

I agree...

Cadillac, and for that matter all of GM spend their time about what people care about.. Good looks, good styling, nice features, good sound system, but everything else may be lacking...

IMHO its one of the things that makes them still around... People buy them because they make sense... If your talking to the average lay person, no one cares about what kind of engineering went into it.. Most people think that after a car has about 70k miles on it, they're worthless...

You may see it as underengineering but if you ask people who make and MOD race cars they may have a different opinion. What is rinky dink about getting another 100 HP or so with some good craftmanship. And if you consider a mustang a POS then why have they been around so long.

So you call people with new ideas chronies huh? I guess only rich guys with no imagination and/or ambition should own these vehicles. By any chance are you republican?

I think you accidentally put your paragraph into Ryan's quote.

Lets keep politics out of it.

I'll tell you what's always lacking, FIT AND FINNISH. GM and most all American cars are like this. Why can't they put these cars together like Japan or the Germans. Don't get me wrong. I'm not and American car hater. I would love that GM made a car that I like, but they always seem to F*** it up. When I first saw the GTO, I said Wow! RWD and all that power, but when I saw it in person, instead of GTO I saw POS. Same thing with the CTS-V. The next car that looks like it will be a knockout, although I wouldn't get it, is the Pontiac G6. It looks like a nice Accord alternative, but I will see it at the auto show next year, and it will look like it was put togetther by blind people. I guess you can always count on the masses buying crap. As long as Hertz, Dollor and all these rental places exsist. their will be a customer for bad cars.

[Jesda]

Yeah, the reliability these days is there, especially with Cadillac, Mercury, and Buick nearly topping JD Powers surveys. But the panel gaps and cheap materials are huge turnoffs. Pontiac interiors (except the GTO) seem like someone took the same plastic used to make happy meal toys and reshaped it into a crappy dashboard.

GM (and economically devastated parts of Michigan) are still recovering from the Roger Smith era. I wish him endless pain and suffering. Because of him, we lost Oldsmobile, but we still have Saturn.

And despite superb build quality, nothing seems to be stopping BMW, Mercedes-Benz, and Audi from building craptastic techno-junkers.

Realy? You think the GTO interior looked good? Sorry man, I cant agree. Looked like crap too.

[louiegz]

I guess they make Vauxhalls and Opels with the same lack of detail as the American GMs.
