Exhaust, duels, crossover, H pipe, or Y pipe?
Hi all, I am starting to look into exhaust for my 76 4.8l swap. What are people running? Are there advantages to running one set up over another? I am not anticipating any thing but a daily driver with this set up, cost is a factor and if possible I would like to do it the system myself with a universal type kit.

Re: Exhaust, duels, crossover, H pipe, or Y pipe?
I'm running an H-Pipe currently and think it's great. Sounds good idling, WOT or regular driving.

Re: Exhaust, duels, crossover, H pipe, or Y pipe?
Dual (not duel, thats fighting people at dawn with muzzle loading pistols) should probably be changed to True Dual.
The h-pipe (x-pipe would be the third option), is on a dual system. True dual is individual pipes from the manifolds back. I run true dual, which is probably the less popular as its a bit noisier and doesn't scavenge. |
Re: Exhaust, duels, crossover, H pipe, or Y pipe?
Darn spell checker came up on dual. Maybe I should be a little more specific:
1. True dual exhaust, no cross over or H pipe, balance pipe, etc.. 2. Crossover or X-pipe 3. H pipe, like on a late 80's mustang. 4. Y pipe, similar to stock. |
Re: Exhaust, duels, crossover, H pipe, or Y pipe?
true duals in 2.25" with either a H or X pipe. Im running an H pipe because its easier to fab in.
don't go too big on your piping. Bigger is not better, atleast in this case |
Re: Exhaust, duels, crossover, H pipe, or Y pipe?
Mine is true dual/H pipe, complete system out the back. I am running 2 1/2" pipe (it was already on the truck before the LS swap)....longhorn

Yall are gonna make me eat a bullet.
TRUE DUALS MEANS NO X-PIPE, H-PIPE, OR ANY FORM OF CROSSOVER. TRUE DUALS MEANS SINGLE PIPES FROM HEADERS BACK, WITH NO FORM OF SCAVENGING! Duals is any 2-pipe system that uses a merge, collector, h-pipe etc etc etc. True duals are like you would find on a motorcycle, or my truck. Individual pipes only! I don't mean to yell, but after my initial post regarding clearing this up, 5 more pop up with the usage. Are we clear, better yet, are we CRYSTAL? http://upload.wikimedia.org/wikipedi...stal-pepsi.jpg |
Re: Exhaust, duels, crossover, H pipe, or Y pipe?
Im runnin true dual, x-pipe, cat back with quad tips.....lol.:lol:
|
Re: Exhaust, duels, crossover, H pipe, or Y pipe?
mines TRUE DUAL, even though I told the guy to put in a H pipe and he didn't, but I let it slide. Although it does bring up a question,,,,,,,,,,which is whenever I'm roaring down a step hill in a lower gear, or under any heavy deceleration, it will pop a time or two, and I was wandering if that had anything to do with being TRUE DUAL??? It's not a huge backfire or anything, just a annoying pop that makes my awesome sounding truck look bad.

Just my 2 bits.
I run a true dual now with side exits, and I would say a H or better jet an X pipe is very important with side exits, as you only get half the engine out each side it doesn't sound as good as both pointed in the same direction. |

Re: Exhaust, duels, crossover, H pipe, or Y pipe?
Hehe, I'm a nazi for nomenclature.
Ok no one quote the first part of that out of context.... Anyway, I just get on people for it because its one of those "buzzwords" that gets thrown around out of context and leads to further misuse. As an example, there is a difference between manifolds, and headers tho the terms are used interchangeably. The use of "true" in terms of dual exhaust has no reason to be used, if in fact, it isn't actually a true dual. I'm not upset with anyone, nor is it that big a deal...but since I have a platform, I'll run with it. FWIW, the reason it began to get misused is the prevalence of "dual exit" exhausts. They are NOT true dual, nor are they actually "dual" at all. Instead they are a single pipe exhaust with a y-pipe on the a$$-end, making two seperate exits. SRT4's, v6 mustangs and others are extremely guilty of this. |
Re: Exhaust, duels, crossover, H pipe, or Y pipe?
No "quote"....don't worry about the spell check, or the "buzz words', spend your time sharing what you know on the gen III ? Hell, I am 57 yrs old, spent 40 yrs playing with the gen I small block! The gen III is new to me, but I still have time to listen & learn ;) I thank you, & the rest of the guys for showing this old man a new way :chevy: Longhorn

I'll run 2.5" system with an X if its in the budget once i get the motor in, if not its true duals out just behind the rear tires. Not sure I'll ever tweak it enough to need 3", especially with the '10 Camaro manifolds. |

Re: Exhaust, duels, crossover, H pipe, or Y pipe?
You guys are awesome, I love a good discussion. The H-pipe definitely seems to be leading the pack. Thanks for the pic solidaxel, that is what I am looking for. I wanted some opinions from those that had actually run the different types of exhaust systems on trucks with this swap.
I had totally forgotten about Crystal Pepsi, wasn't it in between the TAB and JOLT cola's at The Stop And Go? |

Re: Exhaust, duels, crossover, H pipe, or Y pipe?
I had a mustang 5.0l with flow masters a long time ago and I hated the drone. I want a nice sound with no DRONE. I don't know if I have ever heard walker mufflers before. Ill look into it. Thanks

Re: Exhaust, duels, crossover, H pipe, or Y pipe?
I 100% agree with BR3W CITY... Duals are available in many configurations. H-pipe, X-pipe, Cat-Back, Merge and split, ect.
TRUE DUALS are what we did in high school straight off the manifolds and out the back. Mufflers were optional. I even know a guy that used pipes from an old, cheap swing set. Swing set pipes make a different, pingy kind of sound! CT |
Re: Exhaust, duels, crossover, H pipe, or Y pipe?
One knock I've heard about true duals is that it sounds like 2 4cyl engines. I was thinking of have to run either a H or X pipe so I would not have this effect. Since i have no reference to go off of, can you guys who run true duals elaborate on your sound. Thanks!

Re: Exhaust, duels, crossover, H pipe, or Y pipe?
If mine sounds like two four cylinder engines, then each of those engines is a badass.
TBSS manifolds to 2.5" true dual pipes, to (1) blowmaster resonator, then dump out the sides. The biggest gripe is the drone, which when combining flowmasters with straight pipes AND putting the resonator right under the cab....means plenty of it. I sound deadened and put a good stereo in tho, so its actually very tolerable. These two are videos from my Photobucket. This is off a cell phone back when we first had it tuned. http://i112.photobucket.com/albums/n..._VIDEO0004.jpg http://i112.photobucket.com/albums/n..._VIDEO0005.jpg And this is on a better set of cameras, cruising around in-cab.

Re: Exhaust, duels, crossover, H pipe, or Y pipe?
Ill put up a clip of mine with shorty headers and super 44s before I swap in the spintech 9000s I got yesterday!
both duals with a h pipe and dumped before the rear axle. |

on the true dual sounding like 2 4cylinders I would say that is something that comes out with side exits. If you are close to one side or the other you don't get a full v8 sound. that said it it still doesn't sound like a 4banger. look up side tubes like the ones put on corvettes and you will hear it. |
Re: Exhaust, duels, crossover, H pipe, or Y pipe?
2.25 x pipe to 2.5 mufflers and tails, used muffler back that was on the big block
pretty sure it was this kit: http://www.summitracing.com/parts/sum-642122/overview/ Jay |

Re: Exhaust, duels, crossover, H pipe, or Y pipe?
Questions:
1) what are the advantages of the H pipe 2) What is the best location for the H pipe? It looks like there is only room for one after the trans like in the pic on the first page. |
Re: Exhaust, duels, crossover, H pipe, or Y pipe?
Any crossover like an h allows the exhaust to cross paths, which helps with exhaust scavenging, takes some of the harshness and *snap* out of the tone. This is how modern exhausts are designed, and thus what would be "expected" on an LS motor. Not running one is ok as well, but as mentioned, there are a couple of percievable drawbacks.
Right after the trans is the common place for one, since its the first place where there is usually room to run a 2"+ pipe. Anywhere under the cab should be fine. |
Re: Exhaust, duels, crossover, H pipe, or Y pipe?
So my buddy just installed a 4.8 in his truck and started with the stock manifolds and ran duals straight out the back. It sounded good but a little harsh and it had a bad resonance or drone at speed. He went back in and added a small cross over and it changed it a ton. It no long has that drone and sounds good. No other changes. That said I would always suggest a cross over of some type.
His was a 2 1/2 inch system with about an 1 1/2 inch cross over "H" style pipe. Dave |
Re: Exhaust, duels, crossover, H pipe, or Y pipe?
I'm a fan of the x-pipe. I've had enough loud cars (solid lifter BBO with straight 3" true duals out the sides in front of the tires, lol) to be able to appreciate some mellow tones. I used a 2.5" summit x-pipe kit. added in some hedman s-bends and some turndowns and you got a full mandrel bent exhaust for like $200 (minus mufflers)

Re: Exhaust, duels, crossover, H pipe, or Y pipe?
Heres a crappy phone video of my spintech 9000s.
They sound SOO much better than the super 44s and not nearly as loud and annoying as they are advertised to be. https://www.youtube.com/watch?v=TmuOUt9ex9I |
