The only reason I bought my Flowmaster kit was because it was used for a bout a week, and buddy was selling it for half the list price. They sound great, but I agree, all you hear is bad things about them rusting out, Ive even heard they have less flow then a stock system (any truth to that?)

In an ideal situation on a stock to mildly modded engine you will want 600 CFM max.

Yep Nitto, I got about 4 years out of my Flowmaster 50HD. Top looked like a brown, rotted slice of swiss cheese when I cut it out.
I debated between the Cherry Bomb Vortex and Extreme for a bit, but got an Extreme sent to me as a gift, so it made my decision easier.
Vortex sounds great and flows slightly better than the Extreme because there is no internal wing plate. Get it, you won't be disappointed...
