adding a tail pipe/tip

[warhog]

keep in mind, 6.9 N/A (for now )

Alright so the PO of my truck just sawed off the exhaust just past the cab...Well, i'm tired of my rear axle getting caked so it's time to finish it up. Now, my truck already has a dual system started...true duals, one pipe from each manifold. I don't need anything fancy brand, unless there's a true good reason to do so. Browsing the local parts store they have a tail pipe that'll fit my truck for 35 bucks. That's fine with me. It doesn't say, but i imagine it's the stock diameter.

a) any good reason to go up to a bigger size pipe?

b) Since I have duals...can I simply buy two of those tail pipes or are the bends going to be way off?

c) any other suggestions instead?

edit: D) do they make such a thing (no i don't want a whole Y pipe) but just a simple 2 pipe to 1 adapter? I imagine that could save me some dough and headache running an extra set of everything

If you plan to Turbo anytime soon, I would just get a single 3" system.
True Duals do sound good though.
Yes you should be able to get a y-collector. Look on jegs, summit, etc...

2.5" duals
3.5" single na (psd exhaust) my 88 had one. Cheap and it felt better then the 2.5" straight pipe
4" single turbo

3.5" aint overkill for the truck? Can I just use a y-collector to merge the two pipes where they end, then use a 3.5" "cat back"/tail pipe and be fine? I know physically i'll be able to do it, but i'm not sure about the sizes and all that fun stuff if it makes sense for back pressure and all that. I'd rather not spend $400+ on a full system if I don't have to.


edit: screw it, for $20 for a 2.5" tail pipe i'll jus go that route with a y collector. can't complain about that price
