Y pipe, X pipe, H pipe

[Tyler Dean]

This my exhaust set up for my 2007 chevy tahoe dual exhaust with super 44 on. Would switching to a h pipe or duals make it any louder and if so would it sound poppy/crackle which I do not want, I want it to be louder but still have the deep good sound it has right now.

True duals will make it quieter. I had true dual Flowmaster Super 40s (not as aggressive as the Super 44, but is just as loud) on my old '98 and it wasn't as loud as the single in/dual out super 44 muffler on my '14.

 

All an H pipe or X pipe does is equal out the pressure on both sides, but that's only needed for a true dual system that has the 2 separate sides with 2 cats and 2 muffler. With a single in/dual out that's done inside the muffler. Plus, an H or X pipe is usually put in front of the muffler, doesn't make much sense to have it in the tailpipes behind the muffler.

 

Like I mentioned in your 1st post about the exhaust, do you still have a resonator that's maybe in front of the muffler? If so then that's what's making it quiet. If not then I don't know because my Super 44 single in/dual out without the stock resonator or flapper valve is pretty loud and so far is the loudest truck and setup I've ever had. The only thing I can think of that would be louder (not including straight pipes and has a muffler) would be a Super 10 or a glasspack (especially if you clear out the fiberglass from the inside of the glasspack so it's just a straight pipe). If you don't have a resonator then the only way I can think of to make your system louder while keeping the Super 44 is to cut the tailpipes off and have turn downs welded on so you won't have tailpipes and the flow would end at the back of the muffler.

 

 

By the way, you don't have to make a new thread every other day. Just go to the thread and leave a comment to bump it to the top of the new list for people to see it.

So I should just keep it how it is? I'm fine with how it sounds right now I just didnt know if an h pipe would amke it louder. Does h pipe mean true duals? thanks for the help

True duals is when you have 2 separate sides instead of having the sides come together with an y-pipe right behind the engine. It usually goes from 2 to 1 before the cat. So a normal exhaust will have the pipes coming from the exhaust manifolds or headers go into a y pipe which will make it go from 2 to 1 pipe. Then you'll have only 1 cat and 1 muffler. True duals is actually without the 2 sides coming together so you have 2 pipes with 2 cats go into a single muffler that would be dual in/dual out and then the 2 tailpipes. Then you have a proper true duals which is the same as true duals except you have 2 separate mufflers, so 2 complete sides where you have 1 cat and 1 muffler for the left side and 1 cat and 1 muffler for the right side. A proper true dual system is where you'd want an X or H pipe but isn't really necessary. The X and H pipe just equals out the pressure as I said, but with a normal exhaust or true dual system with a single muffler then the 2 sides equals out in the muffler.

 

So basically:

 

A normal exhaust will be the 2 sides meet at a y pipe which turns it into a single exhaust with 1 cat and 1 muffler.

 

A true dual system is the 2 sides stay separated with 1 cat on each side (so 2 cats) goes into a single muffler so it's a dual in/dual out muffler with 2 tailpipes.

 

A proper true dual system has 2 completely separate sides from front to back. 1 cat and 1 muffler for each side so 2 cats and 2 mufflers.
