looks like a good job there...i also did the resonator delete and the guy that did mine did it just like yours, i do like it a lot it made a great upgrade in sound and i think a little better air flow also and they are like maybe 20 lbs or so, i did not but it on a scale but i did take it with me (you never know if it is going to be needed sometime)and my back tells me at least 20lbs HAHAHA .....
