my 93 camaro had original manafolds and y pipe and a flowmaster this weekend i put lt's and ory pipe and had to bolt it back to the flow it sounds better but i hate flowmaster sound im putting a dynomax bullet on it will it hurt it to split it to two 2 and a half to run out the back

 

I dont think it will hurt anything at all but whether a good catback would be better i couldnt tell you. I have Pacesetter LT's/ORY with no cats and after the Y my I-pipe goes over the axle like a regular catback with 2.5 inch piping and just splits up out the back with no muffler and some nice tips, pretty much just deleted the muffler. Its a whole lot louder this way tho but i personally like it. A bullet will help but it will still be pretty damn loud
