Hi, i just recently installed a SLP LM1 catback on my 04' gt. the car used to have magnaflow magnapacks on it. when i stomp on the gas with the LM1's the car doesnt seem to be as fast as it was with the magnapacks on it...did i lose a bunch of torque down low? am i gaining it up high? im considering switching back to magnapacks but i dont know. any help please?

You shouldn't lose anything. The packs are also strait through design just with stainless steal mess inside against the walls.

i know, the magnapacks are pretty much a straight through design too. it just feels like it doesnt pull as hard down low in gears anymore.

sound is amazing though.

You have any times from the track before? Only 1 way to find out, go to the track and see what she does

Butt dyno's have been proven inaccurate on more than one occasion. I know my car feels great one day and like a turd the next w/o any changes.
