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 the Y-pipe and catback your currently running.

I have a ORY and borla catback with cat deletes.

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

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.

any vids of it with the magnaflow?

Im changing my set-up to this as well: one 4 inch pipe off a flowmaster merge. I believe when they calculated internal volume of the pipes, one 4 inch could flow as much as two 3 inch so performance should be top notch with both systems.

i've seen cars run low 10's on ory and magnaflow catback one cam only ran high 10's don' think you will notice enough to be worth it

true duals makes it sound much much better, go for it. I had SLP LM and then Bassani Xpipe dual's. Bassani FTW, search my username on youtube and I have a video of it before I put the cam in it.

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.

i noticed a pretty big difference from my LT lm2 setup to my TDs with bullets

food for thought guys the area of 2 3" pipes is 14 and 1 4" is 12.5 not much difference

sound and clearance at this point

i love my 4" setup, but im pondering duals so i can sump my tank.
mmmm.
been 6.20's 1/8 mile (est 9.80 ish 1/4) on a single setup. all motor.
tough desicions.
