for true dual exhuast do you need another convertor or can it be just custom made second pipe from the orginal converter......or am i just totally missing the point of true duals and.........will i get the same increase in hp if i just add the second pipe behind the convertor without the second convertor?

True duals in my book never combine.

A true dual uses two cats - one for each manifold. As far as "never touching" is concerned, a true dual system can have both sides connected through a "balance pipe" that connects both sides behind the cats. This helps to smooth pulses through the exhaust system, decreasing back pressure and helping the engine to breathe.

do you mean like a "H" pipe? i heard someone talking about it and i just assumed thats what your refering to...... correct me if im wrong

Yes, an "H" pipe.

X pipe would be better.

yes im running true duals on my lt1, two cats and a x pipe, btw its a 2 3/4" system and it sounds dumb without the x pipe

thanx for clearing that up....is $600 a reasonable price for a dual exhaust.......originally one pipe

does that include cats? i payed 900 for mine with borla muffler and high flow cats

i think so...... its with magana flows including 3" tips

do you get inspected for cats and such where you are ?

if not then i would get long tube hedman hedders form summit for these car for 140 and the Hedman X-tensions 2.5": HED-18806 : $21.95
they are S shaped and bolt to the collectors and will get it to where you can connect straight pipes

pipe and mufflers are cheap at local store

good luck

well i have what i consider true duals on my 92 caprice and i have 2 picpes 1 from each manifold into two flowmaster mufflers i think there 40 series with two two turn down tips with no cats i would consider hat true duals .. as for the h or x pipe does that make it do any better ????? please let me know
