Low end torque loss with o/r X?
I've read a bunch of these threads some saying its true some saying its not. What the scoop on this? Right now I have a mrt catted h with flowmaster weld ins. I was gonna go with a o/r H but want to switch things up a bit and get the X.

It felt like mine lost a bit of low end when I put my O/R x-pipe on. Doesn't help that I have Magnapacks either. But at top she pulled much harder. Now with 4.10's, I don't worry about low end anymore.

Technically you don't use anything your powerband gets moved up which is the whole point of doing the mod. Gears will counter the loss you feel. But like SUP3STANG said its not really noticable and exhaust (stock style mid pipe) is for sound only not performance.

Your not loosing any low end TQ with a X or H pipe... it might feel this way, but its all in your head. If anything, your just gaining more up top, so if feels like you don't have as much as you did before.
This is kinda like people who used to say the 4v makes less TQ down low... it only feels that way because it makes more power up top, but about the same TQ down low, so it feels like less.
You should not see ANY drops in the powerband on a dyno with a x pipe, if you do you need tuning. I did not see ANY TQ loss on the dyno before/after, and with full boltons including a o/r X I was making 300 WTQ peak with a super flat TQ curve.
