[quote=High Noon]If your looking for "cheap" I would strongly consider a set of Magnaflows! I can't see how you will beat the Magnaflow "tone" that they are famous for or the performance! And the best part you will not alter the original pipes or M3W in any way. I just helped a M3W customer in California install a set of Magnaflow's yesterday. He will be very happy!

You should start selling the kits, would be a good little business here in the US.
I would certainly be a customer.
