True dual performance gain?
True dual performance gain? Do you guys think that switching to true duals, is worth it performance wise? I know the sound is much better, but will I even notice the difference in power?
Depends on how free flowing your ORY is. Do you have a flowmaster merge? Cutout?
I believe true duals always outflow a Y-pipe set up, but with the additions above, the difference can be made minimal.

You may feel a tiny bit better performance. But probably not much at bolt on power levels. Its more about sound at this point and its an exhaust you wont outgrow. Choose 3 inch pipe.
True duals, if built correctly with a good X-pipe will perform much better in the midrange areas compared to a Y-pipe setup. Peak power doesn't change much, but I've seen a 15-20ft lbs difference in the 4000rpm range on a heads/cam car.
On a stock internal car, it doesn't make much of a difference if any.
BTW, exhaust related topics are considered EXTERNAL to the engine. I'll go ahead and move it for you.

i guess ill add some input/questions
if you consider a 3 inch true dual system with a good set of mufflers
vs
say a 4 inch single with a good flowing muffler and a flowmaster merge
would there be any difference? even in weight? i doubt it
not to mention you prolly have better clearence (if done right)
ive had a few true dual setups and now going to my first 4 inch setup so i guess we'll see

True duals I was also thinking of going true duals, but wanted to go all the way out the back. Almost impossible on our f bodys so I did a bolt on Mufflex 4" with a straight Magnaflow.
It's sweet and not too loud in the car either !
+ I think the true dual setup for me would a been too loud. Just my .02.

I'm not sure if a 4" would be necessary unless you have a 402ci or larger engine. I'd almost be willing to bet you'd lose some TQ with that sized pipe on a bolt-on or heads/cam engine. I've never tested to confirm this though, just theory.

We were discussing one single 4 inch pipe. That doesnt seem like overkill to me considering its about the equivelent of two 3 inch pipes. True you may lose some torque, with a decent sized torque converter it doesnt really matter though.
