x-pipe, h-pipe and other exhaust questions

hi. i have a s10 with a small block conversion (283) thats mildly souped up. my current exhaust setup is dual exhaust that goes headers- 2 1/4" pipes- 2 1/2" dynomax bullet mufflers (the shortest ones i could buy)- 2 1/2" tail pipes straight out the back with 3 1/2" chrome tips. as you can see there is no h/x pipe crossover anywhere and im wondering how big of a difference this would make. how does it affect power and how does it change the sound? i know that an x-pipe is the better of the two options but since the 2 pipes run side by side very close together pretty much all the way back a pre-fabricated x-pipe would not slide right on, making it pretty hard to do. this would also make putting a pre-made h-pipe on just as hard but im thinking a decent exhaust guy could make one pretty easily so that is the route im probably going to have to take. is there another option?? how will the h pipe effect the power and sound compared to an x-pipe? will i notice a difference if i install one? also keep in mind that since the exhaust is nowhere near stock for this truck im going to have to install whatever i choose pretty much wherever it will fit, meaning i might not be able to install it in the 100% perfect spot. is it still worth it? one more question: would it be worth it getting my headers-mufflers piping redone to 2 1/2" to match the bigger tailpipes and make it the same diameter straight through or is it fine the way it is. if i did that how would it affect sound and power? thanks alot

If you were running a high horsepower big block you would probably want an "X" pipe but for your application an "H" pipe will work just fine. In theory they work by helping scavenge exhaust gasses which helps relieve back pressure.

I doubt in your application you will notice much difference in performance but there will be a noticeable difference in exhaust sound. A crossover pipe will cut down the "Rap, Rap, Rap" sound dramatically. It won't quiet the exhaust any but will make it sound more like a "60's" muscle car than one of the old "50's" customs.

the general concensus seems to be that the x-pipe is far better than the h. some people seem to think that the h-pipe doesnt even do anything. is it worth putting it in?? should i just put it in as close to the headers as possible since with my application its going to be hard to put it in the perfect spot because of clearance issues. why would an h-pipe work fine for my application whereas an x-pipe would be recommended for a high horsepower big block?? thanks alot

Simply because you're not running big horsepower and you would never notice the difference between the two. You stated the "H" pipe would fit better in your car anyway so there is no need to go through all the hassle to install an "X" pipe when for your application an "H" pipe will work just as well.

ok i guess that does make sense. so basically your opinion is to just go with the h-pipe and the difference will pretty much be a less "raspy" sounding exhaust and maybe a small gain in bottom end? is the fact that the 2 pipes run parallel to each other fairly close together going to be a problem in installing one or should a reasonably qualified exhaust guy be able to get the job done? since i cant install it until maybe halfway back because of the way the pipes are built going to be a huge factor or will it matter much? and can you buy the t-pipe things to fabricate it or does it have to be made by an exhaust guy? thanks

You can purchase kits from Jegs or Summit for around $30. If you can weld you could do it yourself but any muffler shop should be able to install one in about a half hour.
