Trailblazer lost acceleration?

ok so i deleted the resonator and replaced it with a cherry bomb glasspack and deleted the muffler also. now it seems like it has really crappy acceleration..(getting on the freeway i have to floor it to get it up to speed hitting 5 rpms) im guessing its because its lost almost all its back pressure??? idk.. now if i were to add a muffler to it will that create a little more back pressure?? or how can i gain more back pressure??

Was it ok before?

yes it was fine..

I would say you have too much back pressure, any check engine lite, how can you pass emissions?

no check engine light or anything. it still has the catalytic converter so it should still pass emissions?

I would disconnect the exhaust from the cat back and see how it runs, yes it will pass emissions with an oe cat in good shape.

did that before i put the glasspack on. sounded like a full blown muscle car and accelerated really well at low rpm, but was REALLY loud.

Ok let's see, if ran ok without the new muffler and died when the glaspak was hooked up, so what does that tell you?
