Hi,

My '68 Dart currently has a POS dual exhaust system on it that I managed to "clearance" on a speed bump the other day (the car is lowered slightly). Currently, the car has a stock 318, but a mild 383 is in the works. What systems are out there that fit well, up tight to the chassis that I can use for my 318 and eventually the 383 when it goes in...??

Thanks,

Mark.
 
TTi makes a great system or you could just buy a uni system and build your own.
 
The TTI systems look nice. Which is better for a street car, H-pipe or X-pipe...?? Anyone have a photo of one of these systems installed ?
 
I just used a jegs bolt together one and it fit up close for me. The only thing that I hit is the hooker header on the passenger side.
 
Do NOT get Pypes! The price is tempting (for T304), but they just don't fit. The tailpipes don't match, and the rest of it is badly made universal. If you look at the Dart on their site, even THEY can't get it to fit without tweaking. I wish I was smart enough to have looked before I bought. Ugh!!!
 
I did a Jegs system and it is true dual. I liked it.
You can add in a X pipe or a H pipe for extra money, but, the worth of it all is only up to you. While the H or X pipe add's power and a few extended rpm for the power band, it is a hassle to do. If you can cut and weld pipe yourself, it will not be so bad.

True story-I bought the 2.5 dual kit + X pipe from Summit; AFAIK, the Summit and Jeg's kits are the same. The X pipe requires some fab experience, but it'll fit well-not a spec of rubbing on mine.
 
Hanging the header back kit isn't bad at all-the part that I took to a shop to do was fabbing the front side from the headers and making it fit the kit(s) I bought-if you look in the hedman tight tube header thread, you'll see the pictures (about 15) I posted on page 8. I don't have the welding experience and the equipment that muffler shops have, and this guy came with recommendation, so I was happy to have him do it.

My brother bought the same Summit header back kit a couple years ago, and he said minus some very minor issues, the kit bolted together without a hitch-just one tailpipe longer than the other for some reason. Nothing a sawsall wouldn't fix though. Buying the X pipe though, would make it a little more difficult and would require some welding and cutting.
 
I have a pypes kit. It was a pain to install. If the x pipe was an inch or two further apart it would be a cakewalk. BUT ITS NOT! it was a huge pain in the *** to install. I had to use a ratchet strap to one of the leaf springs to pull the pipe over enough. It did work and it is stainless so it should last a while. Fitment is workable it is just a pain. Now that it is in it works real good no rubbing with 2.5 inch pipe. Would i recommend it? I don't know to be honest.
 
In my experience, any kinda crossover takes away some of the "crispness" of the exhaust note. On a street car, you're never gonna feel the power difference if there is one. It's just not enough IMO to worry about and to me, takes away from the exhaust note, instead of adding to it. I think a lotta people get hung up on sheer marketing. I can throw a turd in the gas tank and show some before and after dyno numbers I made up and I bet I would sell at least one turd.

People that choose the X or H pipe wanted it...regardless of whether or not there is a perceived or noticeable difference, it's about choice more than anything...availability of services and components run a close second.

I've run straight, x, and, h pipe setups and I'm not concerned if either one has more pull than the other. The X pipe does smooth out the pulses a little therefore the note, and that's what I wanted. You do have a point about the marketing angle, and that's the beauty of the market for manufacturers...if they can convince a demographic their widget does more or will make their (add item here) better than it was before, and throw in some testing to prove it, their company makes money.
 
for the money the Summit 2 1/2" is hard to beat and I am sure Jegs to be the same. I caught mine on sale for I think $209 and love it. A friend has a muffler shop and when he saw it he said that he couldn't even buy all the bends, mufflers and material for that price plus these are mandrel bent, Joe
 
This is the Jegs kit true duals with Hooker Headers. Im pleased with what I got for the money spent, not to hard to install. Had to shorten one of the tailpipes a little, thats about it. Have been fighting a leak in the header flange, very irritating.

A friend who is a welder gave me an x pipe he fabricated. Unsure if I want to install it but I thought I might try it with the Flowmaster Super 44. Any one uses them with x pipe? I really like it loud, hence the super 44's.

Mufflers in video is Jegs though, no x pipe or h pipe.

Same deal here on my '74, stock long block 318 (With a bit of water in the exhaust, LOL!) Hooker headers into the Jegs true dual exhaust and there mufflers;

Crossovers make a difference,even on the street.Many years ago my brother had a monza spyder with a wheezy 305 and a four barrel,he had true dual exhaust put on with an h-pipe.When we picked up the car it sounded quiet and bassy and after a couple days he decided he didnt like it so he took it back and had them cut it out.He was really dissapointed he did,we both could feel a substantial difference in throttle response and low end torque and was just not as smooth a driver.I have experience with a few x and h pipes at the track since and my results back up the tests you will find around the various sites.The h gives a little more bass and low end where the x gives a bit more midrange/upstairs and sounds a bit mellower/raspy.
 
Here are a few photos for you of TTI's. This is a 64 B body with a 318
Yes they are expensive but it will be the last set you will need.
Read the instructions and always install new engine and tranny mounts for a perfect fit. I've installed about 12 of these systems so far and the only fit problem was when I didn't check the motormounts first.
Just something for you to look at..
