I've noticed a lot of support for the off road Y on this forum. How much HP can a Silverado take with a good set of LT Headers and single 3" all the way out? Are there any reasons/ advantages to running the off road Y compared to running 2.5"/3" true duals? (with H or X pipe). I was pretty set on duals, but with Forced Induction being far down the road it seems I might be able to do fine with the ORY until I get into the FI realm...
Good for at LEAST 200 HP, maybe more with good quality fuel, like AVGAS.
The stock silverado makes over 200hp....
you mean 200hp over stock?
just go ahead and do the duals now if you're going to do it later. i gained hp with my dual 2.5" over my single ory setup, didn't lose any lowend either
YUP,true duals with 2.5 or smaller works great
I was just kidding.
lol ok. I read it this morning right when I woke up and I was like wtf?
Now if you go true duals what is better H pipe or a X pipe?
Either one will yeild the same results. I don't know where you live but ORY means just that Off Road Y it is not emissions legal unless you have a cat. I say do LT's Magnaflow HFC's and which ever mufflers you want, I like Flowmasters, and true 2.5" duals. You will notice the differnce.
depending on the displacement of the motor, i am thinking anything about 6.0 would work better under a 3" exhaust.. seems like i seen a chart somewhere, i'll try and find it... 5.3 or less 2.5.. i run true duals with a crossover magnaflow muffler.. no X pipe..
