downpipe?

Hey guys, I was thinking about ordering a mbrp 3 inch downpipe. Just wondering if anyone has one of these and if it made much difference in power and sound?
Thanks.

don't get mbrp get a profab downpipe they are much cheaper and better imo. as for sound and performance, you will get a deeper sound (no more angry owl at WOT) and it will lower your egts a bit

I'm glad to hear that the downpipe gets rid of the "angry owl!" Whenever I get time and the money, I'm going to get the Pro Fab downpipe along with the Diamondeye 4" quiet tone exhaust. I want the performance without more sound.
