Vibrant Performance Exhaust

[anandoc]

I know next to nothing about exhaust and gas dynamics, but the 2.5" inlet is a smaller cross-sectional area than the two 2" exhaust pipes leading into the 2.5" muffler (~19.62 inches² vs. ~25.12 inches²). I would assume that would create some back pressure, but as I said, don't really know gas dynamics. The 3" (1149) has a cross section of ~28.26 inches², greater than the two inlet exhaust pipes.

Sounds good. I was just going by what Bryant and bosszhp went with. Oh and hopefully I will have a 1148 by this weekend as well

I'm with Will, and am no expert with exhaust and gas and back pressure and everything. I just went with the 1148. That being said, I'm not sure what the difference with back pressure would be between the 1148 and the 1149.

Man, this thread was a great help for a close friend who chose to go the Vibrant route on his Imola ZHP. He's so happy with his decision. I can't get over how good the muffler/tips look with the ZHP diffuser!

Thanks Bryant. Slater helped me find a BNIB Vibrant 1148 locally at a good price, which I will hopefully pick up this weekend. Looking forward to some exhaust 'vroom'
