Assuming you're using the same pipe size in both, a y-pipe will keep the low end better than true duals will. There's a reason only performance cars come with trues

What engine do you have? I have true duals on my truck and didn't have a loss of low end torque.

Guys, take it form someone that has seen too many dyno pulls to remember from many different cars and exhaust system designs. A large pipe will not kill that much low end. I have never seen a vehicle have "bad low end" from an exhaust change. Does a little move up into the midrange? Sometimes, depends on the car. A little extra midrange punch is desirable for some people.
But then, thats just my opinion...

Then again, it doesnt lose anything to them either.

the ones in the 60's needed the duals so it could breath better at least that i what i think. i mean if you look at the engine size a 327 pushin 450hp is gonna need duals now a 6cyl doesnt produce as much power and therefore duals arent required. All i want duals for is for the sound, i mean im 16 and yeah i would like alot of power but i would rather have people notice me and say WOW taht truck sounds sweet, not look at that idiot with all that power i bet taht he gets a ticket or totals in a week.

"Ha. You see those firebirds and camaro's were V6 models. "
Look again. Even the last years they were made, and back to the early '70's the pipe didnt split until the muffler, yes, even the V8s. Single exhaust until the muffler, then dual tips. NOT a dual exhaust. Let me help you out...

I could go on...
"It looks way better.."
I will agree with you on that.
" ..and performs better. "
Depends on how the exhaust is set up.
And duals were around way before '69. They offered them on '55 Fords
f250rangerexplorer- Thanks, you are pretty darn knowledgable (sp?) yourself

Those HP ratings in the 60's were also Gross Horses not Net Horses. What i am saying is that if you have a 460 from 70 and a 360 from 72 they are the same motor but the power rating is less. the reason is because of the government required them to add on the altinator, Water Pump, Fan, etc. I believe the change was in 71 or 72.
