Message Anyone have some good information (eg personal experience) regarding the amount of noise supression when using high-flow cats vs using resonators in the test pipes? I know cats are not intended to reduce noise, but they seem to have that effect on stock systems.... was wondering if the effect is true for high flow parts as well.

Thanks!
