I know this probably belongs in the external forum, but i wanted to see what you guys thought on this one. Does anyone have any factual info that a xpipe system will make more power than a LM on a H/C motor. From everything i've seen peak numbers look roughly the same but is there a gain to be had under the curve with the duals? Thanks for any info.

That's exactly where true duals make more power than Y-Pipe systems: under the curve. I was skeptical of true duals myself, but there is quite a significant improvement to be had under the curve, though the peak may change only marginally.

Yeah I keep hearing that they produce more power under the curve but i have yet to see a dyno graph or time slip to back this claim up. Hey man your in my neck of the woods, do you ever go over to patton and cruise. I may be going over there this saturday night if i do ill look for ya.

not to mention the sound difference between the two. i switched to true's from the LM cause i was doing headers and cutting the cats and didnt want to bother with modding the resinator to be unsure on how it sounds. i went with the true duals and before the cam lost some low end power cause i went 3 inch all the way out but gained it up top. i plan on doing heads in the near future so thats why i didnt step it down into 2.5

Here's a good example of the power that duals provide under the curve: http://www.ls1.com/forums/showthread...51#post4168351

Hey Josh my car is a red z28 with factory ground effects and ss wheels. Its the only one like that i have seen around the area. Well it does look like the duals provide more power under the curve and definately more torque, I may have to look into a setup by Lanes for me next exhaust.
