really quick exhaust question
alright ive recently figured out that efi manifolds/headers with a y-pipe make the "tri-y" effect and stimulate that torque the 300 is known for. I really like the idea of dual exhaust coming out of the back so im gonna pitch this idea; is there anybody out there that made header to y-pipe, to a 1-into-2 muffler? ind of seems hokey but i bought two exhaust tips that i want to use. i have one of them on my 302 single exhaust and it sounds great.

I am in the same boat as you, I like the dual exhaust look, too. Even though mine is a 200, I am using a Classic Inlines header (2") into a Y-pipe, thru an 18" glasspack (2 1/2"), then dual 2" pipes, followed by a h-pipe/merge pipe and out the back of the bronco. I have yet to start the engine, still awaiting parts. I think it ought to have a nice mellow idle with that rappy inline six rev. I'll let y'all know when I fianlly get the engine running.

it would be one into two muffler if i was to go that route. it is either go that route or go true duals with an H-pipe. its still a toss up on what i want to do. makes ya think huh?

No difference in performance but the H pipe may smooth the tone if your true dual system is producing the dreaded drone which may depend as much or more on the make and style of mufflers you use.

but true duals with an h pipe arent true duals anymore right? because duals with an h pipe are just called dual exhaust
ive read that our motors run best with a hedman header and i think 2.25 inch true duals might be carbed ones tho
small pipe diameter is better for bottom end right? or is it the other way around

It depends on the definitions of "dual exhaust" v "true dual exhaust" and I don't think one will find any definitive difference that really makes a difference. Even with dyno pulls I don't think one would see but little difference if any between a single 2.5 out system v a dual 2.25 out system with or without an H pipe and the ROI in dyno tuning just to satisfy a curiosity would be hugely negative.

In high performance, high rpm applications, absolutely correct. Many hours are spent on the dyno just to get collector size optomized. But on most of our 300's and the usage we put them to there is little difference if any to be realized from jumping through those kind of hoops.

or you can use the old trick and bolt on a long colector peice and draw a line down the side of it with a crayon go out for a rip run and come back to the shop look at the line and where it just stops burning off cut it there and say good enough
im just trying to say you dont need to do extensive dyno runs and all that crap... but doing little things like drawing a line with a crayon is better than taking a stab in the dark
my advice do your homework... dont just ask people... research, study, collect all your info and just make an educated decision its way better than doing it like me and being stuck with something you dont want cuz your listened to someone that "knew what they were talking about"
