The Stovebolt Site Forums The Shop Area The HiPo Shop exhaust suggestions

Today I was under my 46/7 with s10 frame and was wondering what I would do for an exhaust system. The gas tank takes up the drivers side. I really want to run dual exhaust. Are lake pipes an option or are they way to loud, I want it loud but I still want to be able to think while driving. Any and all suggestions welcome. Dave

You could move the tank to the rear, behind the rear axle. I installed a NASCAR-type fuel cell in a friend's 66 Mustang because he was a little spooked by the stories of rear end wreck fires, and there are several sizes of them that can be adapted to the S-10 frame easily. They're also fairly inexpensive.

I have a set of Thrush sidepipes I'm planning on putting on my 41 3/4 ton. I don't think they'll be too loud. May get some "unusual" glances though

On my S-10, I cut the Y-pipe, (where the two pipes make one)to make duel exhaust.Ran the pipes down the passenger side. I installed mufflers just in front of the rear axle then piped over the axle and exited pipes either behind each rear wheel or both behind passenger rear wheel. I ran both configurations and also tried regular mufflers and glasspacks. Depending on the configurations all produced their own particular sound! I liked the stock mufflers exited to the same side behind the passenger tire best! (This was using the stock v-6 motor)

Built several V8 Luvs with tank on left side and did exactly as Frank suggested. First couple had one pipe bent to give traditional dual exhaust under the back bumper look but last ones had very warmed over 406 small blocks with both pipes dumping out of turn downs at the right rear wheel like some Pontiac Trans Ams. Liked this "Sleeper" look better.

Does their have to be any crossover or interconnect or whatever it is called or can I just run 2 completly seperate runs? Dave

In my opinion, it comes down to what you want to do, and how fancy you want get. All the vehicle magazines (and vehicle owners)are still arguing whats the best...... pipe diameter, mufflers, headers, manifolds, steel, aluminum..........NEVER ENDS!


"Y" pipe simply gets exhaust from both sides of a V-6 or V-8 to a single pipe or single exhaust. Older cars/trucks from the factory with duel exhaust ran what is called an "H" pipe. This was, in my understanding,to equalize exhaust pressure and help exhaust pulse. This continued for many years up to the 90's(?). Now the hot item is "X" pipes! The "H" or "X" pipe is to be installed at a point of where the duel pipes are at their hottest. (This is JUST MY understanding!) Once the duel exhaust is installed, lightly spray paint exhaust system and let dry. Start motor. Where the paint burns off on both pipes, first, (closest to each) other is where the "H" or "X" pipe should be located. REPEAT.....THIS IS JUST MY UNDERSTANDING! Hopefully, someone with "MORE KNOWLEDGE" will chime in!!!

Personally, in ALL my vehicles, with duel exhaust......I"m just running two pipes with two mufflers! I Like to keep it simple!

Had the Lake pipes, (283 SBC) they were just too loud and the fumes were just to much. I removed them and have true duals through Cherry bombs right straight out the back. Sounds good and no gas mask needed.

here are some build threads with pics of running exhaust on the passenger side

I would not move the tank. The S-10 tank is in a good spot.

What we do is have both pipes go over to the passengers side. My mufflers are upright side by side on the passengers side, and then the drivers tailpipe crosses back over after it jumps over the axle.

I wouldn't go with lake pipes, personally.

I have an h-pipe, Since I had my exhaust done by a reputable shop (only thing I didn't do myself), they knew exactly where to put it. It doesn't hurt to put it in, but it's not necessary.

As far as mufflers, flowmaster and other companies have sound clips on their websites. I went with the 40 series delta flow flowmasters and they sound great on my 455. Quiet enough, but noisy when you're on it, and no drone in the cab.

Whatever you do, make sure the exhaust exits clear of the body and behind the rear wheels for the least noise inside the vehicle.

Some thoughts about separate duals and "X" pipes. There might be a tiny scavenge effect with the "X" configuration(might). The might be less "bark" in the sound from the "X" configuration. The muffler(or lack of one) will change every thing. Warning: Opinion! I like the pipes to exit the rear. Run the duals over the rear axle, and route one to the passenger side. Use a sheet metal heat shield to protect the MC and the bed. I like the "stock" look of these trucks. I like sneaky trucks. My 2 cents.
