Hey Matt! Thanks for the comments about the hearse exhaust. The mufflers are "Cherry Bomb Turbos" which are made my Cherry Bomb, but are not the red-bullet glasspacks. They are offset, more typical looking mufflers. The exhaust is 2" in and out... I believe. It may be 2 and a quarter in and out... maybe. I'll have to measure it and get back to you. The mufflers were bought through Canadian Tire. Are you watching the video in the shop right after installation, or the one filmed at night pulling the car into our own garage? The second video (filmed at night) has less echo and background noise, and will give you a much better idea of the sound of the car. It is very mellow, but has a killer tone.
