X pipe, Y pipe which one is better?

Hello y'all

I was just wondering what would be the best exhaust setup for my 318. I would consist of headers, cherry bomb glass packs , then straight out under the front quarter panels on my tucks bed. (no Cat)

Ive read about x and Y pipes, and read their purpose. I was wondering what I should use. I don't want my truck sounding like one of those redneck truckers (Gibson catbacks) or a rice burner (to tinny). I want it to sound like a muscle car with a good ole' V-8 inside.

That 'good ole' V-8 inside' sound is best produced without any alphabet letters at all. No X, Y or H. It's the odd firing order of the V-8 that produces this, and any crossover device will dampen the effect.

A big single system which is what the "Y" pipe is, will work fine for your 318. I am running one on my '95 Sierra. Edelbrock mid-lengths with their 3" "Y" pipe running into a single in/dual out muffler with 2 1/4 tailpipes out the back. It sounds nice and has a very commanding rumble even with the stock cam.
Another option would be running a dual in/dual out muffler (if you can't find a "Y" pipe for your application) which will give you the same basic performance benefits as an "X" pipe with out the added cost of the "X" and another muffler. This will increase your lowend torque a bit which is what you want with a smaller cube motor.
I will tell you stay away from the glasspacks. They don't flow and can actually create an obstruction in the pipe. Go with a good aftermarket muffler, you'll be happier with the sound also.

Quick question here

I Like the idea of a dual in/dual out muffler, but I've got a question then about placement.

I freely profess to not know much about exhaust systems, but want to learn. Does the placement of the muffler then need to be closer to the front of the vehicle to reap similiar benefits of an X or H pipe? If so wouldn't that change the sound coming out at the end of the system if the exhaust tips are substantially further down the vehicle?

I guess I've just always seen those X/H pipes up front.

Again, I'm sure this is a very newbie question, but just want to learn.

I meant for the Y pipe to be on each exhaust side, coming off the glass pack like a exhaust cutout.

Put the muffler where it will fit... Your stock 318 isn't really gonna care. Optimizing the "X" pipe location will possibly benefit some but it's not really enough to worry about on a driver motor.
The sound coming out of the pipes will be mellow and smooth with the cross-over muffler and a couple feet fore and aft isn't going to have much effect on the tone.
You said you DIDN'T want a riceburner sound so stay away from the glasspacks and true duals. That set-up can get pretty sharp toned and barkie... Been there, done that.

if you want the best you need to go to jegs.com in the exhaust section and check out the electric cut out motors you put in your pipes and control from the dash.stacy put them on that 1972 C/10 truck he built on TRUCKS,spike t.v.,with the 720c.i..you open or close them at will to what ever sound or performance level you want.you will want to install the cross-over in front of the cut-outs for sound and performance though.

Do you want it to sound deep and strong or like a pissed off bumble bee? Cause youre gonna get pissed off bee if you go glasspacks. I can understand what youre going for if you want people to know youre coming from a mile down the road, but I think turbos or those Edelbrock SDTs sound so much better, man.

It was a 67 C10 with a 572 ci engine. Cutouts are a good idea though, man.

I run an x-pipe on my Chevelle and it sounds awesome. Even though it is a 6 cylender, it sounds very good. I sounds different then a v8, but great nonehteless. I run headers, to the x-pipe, to dual Flowmaster 40's to 3 inch tips. True duals, 2.5 inch piping the whole way.

Maybe this system will be of interest to you: http://www.torquetechexh.com/nascar.htm

My 3 inch system with DynoMax Super Turbos should be here next Friday and will be replacing the Flowmasters that are under my cab so I can hear the stereo.

Instead of coming out in front of the rear wheels, I'm going to try going outside the frame rails, up, and straight back with the muffs under the bed. I'll post some before and after pics if anyone is interested.
