I would think you would want the single center in single center out. Simple is better in this case unless you see a need to move the pipes as you go towards the rear then you could do center in side out but I think center is still best but it is like 4AM so what do I know? JIM

How about asking the guy that is going to bend your exhaust.

This is crazy, I was just about to ask the same question. In my case, I'm getting a 3 inch X pipe kit, Hooker Aero Chamber mufflers, ending at the mufflers until the truck gets lowered. Eventually, the pipes will go through the crossmember.
So same question, between X pipe and crossmember, which in/out did you use?
Sorry about the thread hijack.

Well muffler shops mark up the flowmaster mufflers out here so I just know I could save $$ by ordering them with my new carb I gotta order.

Some shops wont use owner supplied parts (so they can gouge you) so i just move on. In my experience with coil spring rear axle trucks, if you ARE NOT cutting holes in the control arm crossmember to run the pipes through it, you need offset in AND out mufflers.

Btw, i recently installed a mandrel bent dual exhaust kit from LMC. It fit great after i figured out they had mislabled everything left and right (!). It fits ram horn manifolds but you could cut the primarys for headers. It was under $250(+ shipping). I am 99% sure it is made by heartthrob. Im not a big lmc fan but couldnt find any better price than lmc and had credi there for parts i was sending back. No local shops would do a crush bent system for this price. He included mufflers are pretty quiet ,but that is what i was going for anyway. My flowmaster 40 days are over. Had them in the past to attract the ladies and mission accomplished!

you go into shops in here and supply your own parts they just up the cost of the tubes on you for cheeping out and cuttin into thier profits for thier job// if they will do it alot will just show you the door for your bad manners

Well I'm sorry , I'm not paying $250 for a pair of 40 series mufflers.
Some shops may like bending people over and price gouge on parts, so if thats bad manners I wouldnt want to give them my business anyways.

Back to the original question, I'm ordering the x pipe, then ordering the mufflers later.

Draggin49, do you know where you are going to mount the mufflers? I have a long box, so I'm hoping they'll fit between the X pipe and crossmember.

[WIDESIDE72]

Your mufflers will have to go in the bed area (right behind the control arm x member on coil trucks) x pipe or not, unless you want them hanging down so low that they will drag on everything. If you search the forum you will find photos of installed exhaust system with and without x and h pipes. "A picture is worth a thousand words" when it come to how the system will be configured.

Routing is the biggie here.If you don't know how you're going to route the whole system,you're not ready to order.I've seen pipes routed to the outside of the frame and the mufflers tucked up between the inner and outer bed sides.then back under the frame and out the rear.Offset in the mufflers can make routing easier or nearly(if not) impossible.This means laying out what room you have under there for the easiest and best routing for your application.
