Default X pipe or H pipe?

I'm thinking about doing the gotts o2 mod and deleting my rear two cats. I was wondering if I should run a X pipe or H pipe or just leave it alone? 5.4 true duals into flowmaster 10 series. Any opinions would be great. Thanks!

Non foulers? That's not too smart IMO. You be leaving something major out. - Unless you care nothing about performance, or , -unless you getting tuned to run TD's.

Well wait, I guess it wouldn't be too bad if you kept the upstream converters, and reduced the duals to 2 or 2 1/8".

What are your plans or what are you trying to achieve. There has to be more to it if your doing something that to the truck.

BTW- with the correct set up, X-pipes for trucks, H-pipes are usually for stang set ups.

I am trying to achieve a bit more performance. I will be getting a sct tuner here soon. I will leave the front 2 cats. So do the gotts mod and X pipe?

The difference in performance will not be noticeable with either.

The sound is what makes a difference. Bullet mufflers like LM1's & LM2's sound like wet farts with X-pipes. H pipes make it sound much less like a turd.

X pipes sound better with Flows/Turbo mufflers unless you really want that musclecar drone down low then go with the H pipe. Some people like it, some hate it.

But as was said above it's mostly a Mustang modular thing.

You'll need to take it to the shop and have them look at it. Chances are unless it's an Off Road specialty shop, they won't be able to give you an actual price unless they're going to just over charge you on purpose.



If you call, the price you get will either be high on purpose or so low that they end up charging you more.

Figure out what you want, true duals, mufflers, cat delete, etc.. get all your parts together (or at least be able to show them what parts you want) then take it to them and ask, "how much to install this?"

Cat delete (if you want to do it) could be touchy since it's federally illegal for them to take off any working emissions stuff.

As a general rule, x-pipes free up a little more HP than h-pipes, due to better exhaust scavenging but the x-pipe produces a more raspy sound whereas an h-pipe produces a deeper tone.
Either one will improve performance over the original set up or even a true dual set up without a crossover, but I doubt it will be very noticeable on a stock engine.
The biggest difference will be the sound.
I've read multiple articles about pipe sizing for dual exhaust systems and as a general rule, 2-1/4" duals are good for up to 360-370 hp and 2-1/2" duals are good for up to 400 hp.
Oversizing your pipes can hurt performance by reducing bottom-end torque.
