No, the car has 2.75" stock. I had thought about going with 2.75" with my custom exhaust, however it's challenging to find the parts you want with that size. That's why I went with 3".

Oddly, my wife and I took a ride yesterday and I let her drive. I don't know why but it sounded louder sitting in the passenger seat. I think it was just because I was relaxed and not focused on driving.

I could have sworn they had 3 inch pipes I believe the 15 ss did also. (dont quote me tho)

Any videos or clips of it while not in a garage?

Promise to do another video out side and one from the inside when I get a camera mount.

sonnydurden, I was able to get some sound bites of my exhaust with the auger inserts. The first video is with camera sitting behind the car and the second is the camera behind the car with some wash mitts over it to help the mic in the camera pick up the sound a little better. These where both taken right at the garage door if that helps with what ender2664 said. I hope these help some.

Thank you!
I wouldn't mind my car being a sonic boom, infact I'd prefer it! But:
1- my dogs are in the car a lot and I don't want to make them suffer.
2- It would be nice not to piss of my neighbors eveytime I start the car.
Im far more worried about number one.

3- Is it illegal?

Ha ha, just joking.

For this sonic BOOM, I would reuse the OME tips, if find them much nicer than the aftermarket straight shaped ones.
