Tips or just larger pipe?
I have an 86 f150 efi 302. Im lookin to change out my exhaust system which is too big for the truck (3 inch). I am realy considering a true dual 2.25 from the manifolds back and than after it gets over the rear axle switching it up to a 3.5 inch exhaust exiting under the rear bumper.
Originally i was gunna run the same setup except instead of puttin the larger pipe on there i was just gunna get 3.5 x 24 tips.
To me i dont see a difference but maybe someone on here can point it out to me. Also, how would the sound of this setup be? thanks everyone, you all have helped me alot on my truck so far.

3.5x24" tips will probably go back almost to far, if you went with the pipe you would be gettin maybe another foot of 3.5 in pipe, than if you went with the tips.
Just somethin to think about.

I'd come off the manifolds and exit both pipes behind the rear wheel or go with a single exhaust. Come off the manifolds with dual 2" or so pipes into a nice smooth y, into a single 2.5" pipe.
Heres a pic of an Edelbrock cat-back for your truck that is a nice system. It exits both pipes in the stock location. Saw it reviewed in a magazine, its a nice system.

Dual 2.25" pipes is slightly larger than 3". If 3.00: is too large, dual 2.25" is going to be worse. If you want duals on your truck, I recommend dual 2.00" with 2.25" or bigger tailpipes. Or run a single 2.5" with dual tailpipes out the muffler.

BTW, 2.25" pipe isnt gonna hurt anything. IMO, 2" is an insult to a great engine.

Ya tell me bout it!! I could have got a dual exhaust glasspack system for my truck for 25 bucks. As soon as i looked at it, it had 2" pipe. I just walked away. The whole system was new tho.
4" pipe? That was my first thought for mine too but got to thinking it might be too big. Guess not. I'll look into the difference in price from 4 inch to 3.5.
What kind of mufflers did you run on yours? Im thinking about dynomax bullets but not sure yet. I want something that will be loud and deep but at the same time have a nice tone to it.

Cant remember what mufflers I was running then. I have tried at least 1 model from every manufacturer you can imagine looking for that perfect sound.
I did like the Dynomax mufflers I had. They were bullets. Pretty loud. The big pipe at the rear will give you all the "deep" you will want.

Ya I know exactly what you mean by looking for that perfect sound. I am really thinking by doing this setup I will find what I am looking for.
You wouldn't happen to know where I can find a set of bullets for fairly cheap? I know on summit they want 50 and 57 for theres.
Also, how would the the difference in case length affect the sound. 12 inches vs 18 inches
