I have a speedwerx single pipe on a 05/M7. Its a stock can right now what can would work good with the pipe should I match it up with a speedwerx can not sure what to do??? thanks
I've been running the SW pipe/can combo on my 06 M7 this year. Just didn't run all that well, BUT I had an RKT head as well. Running quality improved greatly when I added a Y-Pipe and bigger air horn.
