exhaust ideas

Planning out my exhaust setup for the power ram, I'd like that muscle car sound, however I still want to make a 2 1/4 stack through the bed like a bulldozer. Any ideas?

I don't think you'll find any stacks in that small of a size, but you need to keep the pipes that size till they hit the stacks so you don't loose a lot of low end with the 318.

yes I understand about that, what I mean by a stack is just the 2 1/4 going up through the bed.. not an actually chrome stack.

I see. You know you could run 2 1/4 all the way up as your stack and place some chrome stacks over that just for looks you know. And that way it wont hurt performance at all and still look good. My main concern is getting rainwater inside the pipes and causing them to rust out from the inside out long before they should have too. The muffler shop guy can at least put the mufflers on a down hill slop so rainwater wont go inside them and rust them out.

I was also going to use a exhaust flapper on the top. hmm Wonder if I could do some kind of y pipe and have two?

What, two pipes on each side? You could do that with a Y. If you mean one for each side, just use an X pipe for more low end torque and you can run dual stacks, one on each side.

You can mount lake pipes (use to put them under our cars... long chrome pipes with a curled end for the exhaust to go back, not up)... they look great.. as for exhaust flappers... Forget It! They, at an idle, rattle so badly they'll run you out of the cab... been here, done this...
As for the rest, the vertical pipes behind the cab sound great, look great and do their job really well... If you need to know how long the exhaust pipes should be before you put the exhaust assembly together, contact me and I'll give you the length of pipe for what you do the most... you'll also get the best exhaust note out of it.

On my 68 D300 I put a 361 truck eng. in it with 2 1/2 " dual pipes into 2 1/2x36" glass packs, 2 1/2" to the back of the cab, 4" elbows and pipes up the space between the cab and bed (utility bed). It isn't real loud but has a sweet sound to it at 65 mph.
