sorry k-speed i never used the silencer so all those are without it. its not too loud inside sometimes i forget i have it. from the outside i have been told its pretty loud though. with the windows down i hear it, a nice deep rumble. to cut the old exhaust you make a cut right after the rear resonator i believe. i rented one of those exhaust cutting tools from autozone and it didnt do nothing but score the pipe. so i used a dremel for 40% tight fit and sucked and then hacksawed it. if you have a better cutter it can go quick but leave yourself some time for this if you are cutting. but yeah look under the car and right after the second resonator you wanna cut(this would be going back towards the tip. to install the greddy isnt hard cause its two pieces already. bolted up nice onlything i had to do was push the canister towards the drivers side of the bumper cause it was resting on the bumper. but it has never moved back and i am very happy with it. i got mine from optionsauto.com but they are in cali and saved me shipping time and money, jscspeed.com has them and he is a member here. so find someone willing to work it with you and i recommend two people for the install cause the length and weight of the pipe might be fun alone. well take care and let me know if i can help further.
