True Dual exhaust

[flareside_thunder]

I was wondering if anyone had true duals coming out in front of the back tires on a truck with dual fuel tanks....and if you did I'd like to see some pics of how you did it. Eliminating one of my tanks is not an option....I like the option and I always use both tanks.Thanks.

Cant see big deal . Around here they have duals coming out right under rear tank filler to the side . As long as not running at fillups . should be OK . As for the pipe running under tank most hot rods /and small shop set go right under tank.

I did it with the 86 F350 I had .

right under the front tank?

wouldnt the heat from the exhaust cause the fuel to kinda boil?

Never had issue with it . Had 460 and 4" chrome stacks cut to run under tank. And they got hot .

Like said front, back what the difference. Put larger pipe over one used to act as a heat shield over pipe if worried about it . But I drive in country little stop and go . We'll see what others say .

Could also wrap it with header wrap if the heat is a worry.I dont see it being a problem as long as it is not touching the tank.

What about a crossover / pressure equalization pipe?

Thanks man......

I was thinkin that I think a H pipe would be absolutely needed.

 

[Skandocious]

I agree I'd go for an H pipe.

Go X like on stangs, you can get em cheap on ebay. On a 2wd truck, id say it will be easy to make duals. If I didnt have the tcase in the way I would make a sweet setup. Wail till the lightining.

Isn't an X pipe the same as running a y-pipe that splits to duals? Because at the center of the X you are essentially combining the two pipes down to 1 pipe the same way you would on a Y-pipe setup like stock. Technically my truck has true duals and an X pipe, except the center part of the X got stretched out to about 5 feet long

I prefer the sound of straight through with long tubes, no X or H. By the way im in cali right now, and Im jealous of the rustless frames.

 

[wizzard351]

an H or and X isnt goin to make much difference untill you get into big inch high HP engines. for the extra cost of installing an H or X i wouldnt bother. i run 2 1/2" pipes on my 92 and 3" with flowmasters on my 96 with a 460

Run the drivers side on the outside of the frame. My cousins trucks run that way.

ive always felt the same way too... but some "experts" claim its not cuz the flow gets divided between the 2 pipes... with the way the stangs x's are designed (since someone mentioned stangs specifically) the X isnt all that wide.. less you get a crappy designed one... where with the Y's its combining and staying that way the rest of the system...

personally id rather have the H as well mainly cuz they sound better than the X's...

theres also another thing ive never understood when people want to talk about exhaust, its the engines "firing orders"... always hear people saying how certain engines have "even firing" where others are not and are the reasons they need "balanced exhaust".. ive just never understood this point.. seeing as how no 2 cyls are firing at the exact same time to begin with.. so if it it needs done with one engine it should have to be done with the others as well imo...

Yea people say that about stangs my gen, fox bodies. I ran no H or X and it was all the same to me lol, I have a BBK X now. I think the balanced exhaust was to help with scaviging or however you spell it, I remember something about it in school.
