Dual Exhaust Q&A

Dual Exhaust Q&A
The guy at Discount Muffler wants to put 2 1/4" pipe true duals on the truck with glass packs for $350 + tax. I want 2 1/2" but he says that because the exhaust manifolds are 2 1/4", he thinks i'm throwing my money away. 2 1/2" duals with glass packs would be around $370 plus.
I can also run them together in a single, large muffler and come out of that with 3" or 3 1/4", which he says would give a deeper sound. Not sure if i want a deeper sound or a little louder one.
And where should I have them run the pipes? Duals out the back? There's no spare tire rack on the truck right now but i really need to put one on, and he said that he'd have to route the pipes around it AFTER I put it on. Anyone dump duals out behind each wheel?
Thanks for the help.

All depends on what you want, if you want that annoying cackling sound you'll get from small pipe and glass packs then thats what you should do.
If you want a nice running, nice sounding system do 2.25 head pipes and blend them into a single 3.5 (3.25 if you want) into a full flowing muffler then wherever you want to dump them out. Just make sure the 2.25 is well blended into the 3.5, not restrictive like stock.
-Enjoy

nice! hey them are long glass packs.long and duel like that,i bet it's not to loud.or does she bark at ya pretty hard under load/WOT?
did you notice any gain off idle with the duals,or mainly less restrictive while going down the road?
at any rate,that's a sweet clean install.congrats!
that just set ya back a dollar,but perhaps latter on,you may or may not want to,but here's what i'd do with this setup.
right here,in front of trans cross member(if possible.the closer to the engine the better) would be to install an H pipe.all it is,is connecting both pipes.it's said to equalize pressure between the two pipes,for a smoother sounding tone.also said to help low end off idle torque/throttle response.
would be totally cool to hear someone with the IDI who ran duels with and without and H pipe.just an idea.
man,that's cool.

Ya got a bolt-action in that truck? No way you could run the pipes like that with a monster like the E4OD... I'll be doing something similar soon, only pipes will be in the over-under configuration, into my Flowmaster di-so muffler (currently used as a si-do setup, but it's reversible), with a 3" pipe all the way out back (can't exit on the side cause of mu mudflaps and the lights on them and the wires that power them)...Gotta get my new tank in first tho, cause that one will take up all sorts of space under there.

overall it is nice!! the corners are crushed down but hey, such is life! So that guy did that for 350ish? Wow if so. Still cant believe that he would have installed it like this without dropping the pipes down from the manifolds. If he did drop it down then he was a peniz for not cleaning the rest of the pipe up. hahaha. Nice pipes bro! nice pipes!!

you hear the engine more because the new pipe is single wall. I think that is why ford did that to them, the double walled pipe from the manifolds i mean. When i did mine, it sounded like something went wrong, like i had sticking valves. Get used to it, i re did the flanges and everything, still chattery. But with my new magnaflow, i make vettes jealous. hahaha.
