what is this?
http://i79.photobucket.com/albums/j141/sho...es/IMG_0610.jpg
I was looking at an S2000 on a trailer and noticed what I believe to be a pre-silencer. I had a 350Z before and it had one of those. If this is a presilencer, has anyone removed it and welded a straight pipe in its place?
I did this on my Z and it increased the sound volume drastically in higher RPMs, while maintaining stock volume under 4,000 rpm. Anyone done this? Reactions?
PS- the pipe closer to the engine with the O2 sensor is the cat, right? I was under the impression that we had more than one?
thanks

do a search and you will find threads about people doing this for sound reasons.

I thought the Helmholtz resonator was the pipe that sticks out at a 90 degree angle between the silencer that is circled and the catalytic convertor.
