 Subject: dual exhaust question
IP: Logged
Message:
OK I have dual exhaust on my dakota, It has a nice mellow tone at itle but when you punch it it sounds like crap. So I am gone to either put a glasspak on it or run straight converter. It has a cheap cat back muffler on it now. I want to run it straight because it will cost around 50 bucks to do it and 75 to do a glasspak. buy my question is if i did run straight would it have worse gas milage, if so how bad would it be.

better keep a muffler on it. gas miliage will not go down but performance will. Your engine needs a certain amount of backpressure. without this it will run like crap also. Ravin mufflers sound damn good on dodge.

Its not like I am running straights from the manifold, I will still have the cat on there. That will help with some backpressure.
can any one else help me on this because I am going the get something done about it on saturday. please help if you can

So run a cherry bomb glasspack muffler. They're welded, are straight-through design, and sound great. Prices are $15-$30 at Auto Zone and any other big Auto place.

I work for salvage yard and I drive a 00 Dak 5.9 and all the bells and whistler and yadd yadda. I also found taht with littel modifying you can convert a Dual flowmaster kit for a 1999+ Dodge Ram 1500 to fit a dakota all you need to do is shorten it just a bit. However match the engines 5.9, 4.7 bl bla bla. The sound is great smooth yet non-riceburnish, get beefy with out that trailer Ford white trash rumble.
I also have a wrecked 2002 QC Dakota that I'm selling as a rebuild price includes all parts. check it out... http://shawautoparts.com/Details.asp?ID=1101

I have a 99 dakota that i ran just the converter on it. (no muffler at all just a pipe). It was pretty loud but i didn't notice any change to performance. i say if your on a budget and just want to hack it, go for it.

I still cant believe this board sometime.. Back pressure this and back pressure that. BACK PRESSURE is bad people, get it throught your skulls. Back pressure is not your friend, and never will be.

With a 2 ton truck, TORQUE is MY friend. A little less restriction can be good. Too much can kill torque.

Kowalski, does the throttle body combined with the HO cams drop low end torque and move it up the rpm scale? I'm interested in towing and hauling not racing. I've currently got headers, Int Per air and a custom PCM tune. The KRC HO cams look like the final piece of the puzzle for now.

I've heard the HO cams increase power everywhere, and my experience with them would back that up. I tow a 24.5' fifth wheel camper or a 19' cuddy cabin and didn't feel a loss of torque anywhere - felt a gain from down low. Replacing my 65mm TB with a home ported 68mm seemed to have slight higher rpm gain with no noticable loss of low end. Go for it.

bad dakota....You would not lose m.p.g. It would be potentially very loud. It would potententially backfire. I'f loud is what you want, get a flowmaster 40 series with a down turn after the muffler. You can get these muffler's pretty cheap. You'll get tired of it after a while though. A friend of mine has this setup. It gets annoying to me after about 5 minutes.
Disclaimer...the backfire comment does not apply to all daks with a glasspack. I've heard some daks equiped with glasspacks that do back fire but not all do.

listen and learn
less backpressure does not kill torque.
It shifts the torque peak to a higher rpm and/or
spreads the torque over a wider higher rpm range.
in the end you'll have more torque than you ever had...it just moved to different rpm's.
If your top end torque is great and your low end is weak..time to take advantage of the situation with gears, stall convertor, maybe a pcm flash for higher rpm shift points.
faster than ever.

bad dak,
Everyone has good recommendations, but since you're on a
budget I don't think you can afford most of them.
If money is most important, and you don't care about a ton of
noise, then by all means just put it straight. Your power/
mileage shouldn't be worse, and will potentially be better on
account of backpressure. You don't want zero pressure, but
with your cat, you should get more power. This should be cheap
and make you happy with performance. It will be obscenely loud
though, but if you don't mind then more power to you.

Folks without the proper modding process, you can open up the system and potentially lose power. This is due to a lack of exhaust gas velocity and heat (call it exhaust energy). And by the way, there is no such thing as backpressure in any 4 cycle engine (there is backpressure where turbos are concerned, but that's another issue).
What you need to remember...exhaust velocity (related to scavangeing).
What you need to forget...BACKPRESSURE!

Why do you call it DUAL EXHAUST in the first place when you are mentioning a single cat, pipe , etc. I think installing the dual exits is just FAKE sh*t in my book.
Now if you got what Demon Dak above has (it's why he has to call it TRUE DUALS) then you have dual exhaust.
If you do not have duals form the manifolds back, then call it dual exits or something.
I have a 40 series Delta Flow with the tail pipe stock. It's loud outside, almost too quiet inside when the windows are up. No Flowmaster drone at all. It sounds fukking good.
When I go duals, it will be dual cats and dual pipes all the way out. I'm just too worried it may not sound as GOOD as it does now.
In fact here, listen...
