hp gain with true duals
hp gain with true duals what kinda HP gains will i see switching to a true dual exhaust? I know its not much but just kinda curious. Sig below shows current setup and im going to keep my cats/H-pipe/spiral flows over the axle. Like i said im just kinda curious. TIA guys
no im getting a true duals system with a H-pipe. I have a TSP Y-pipe and hooker catback and QTEC cutout. I might wanna add that the true dual system will be crush bends

yeah clear it up all i meant was that im keeping my cats. thas all

True duals are going to give you more midrange tq, because of the scavenging effect of the xpipe. They usually don't give much if any hp over a good ypipe setup because up top those flow pretty good. It's going to be the midrange where you're really see the benefit.

Verdad Gallardo Yes, even with crush bends. You are not going to take a huge hp hit until you are making some serious rwhp, even then the hit will be minimal. Just make sure you have a good volumetric xpipe, an hpipe is not going to scavenge nearly as well, if at all.

The speed of the exhaust gases vary as they are higher rpm. At lower RPM there is a scavenging effect of the xpipe, just like long tubes, that increases the velocity more than stock, because of the pulses of the exhaust coming from the engine. As the speed gets up there to upper RPMs, there is less scavenging effect and consequently the pulses are so bunched together they don't scavenge as much, hence the same hp as with a good flowing ypipe.
Technically you can tune an exhaust to scavenge in a certain way. That's why equal length primaries on headers are so important, because they allow the engine more scavenging. So tuning True Duals to place the xpipe in the best location possible (as close to the headers as possible) will result in more efficient scavenging, at midrange rpms, where the effect of the pulses are greatest.
