Hey guys,

Im thinking of running 2.5 outlet tp, with 3 inch aam y pipe, to a 2.75 inch midpipe/muffler. I know it will rasp, since its going from a 3 inch to a smaller diameter piping. When i had the 2.5 inch tp with hks dual, which is 2.25, it rasped a lot. Will this setup rasp a lot too? Its a bit bigger than 2.25, so that is why I am asking.

Also, anyone interested in switching an aam 3 inch y pipe if it does rasp a lot?

Steve
