yea in my video on youtube all i had was the megan racing exhaust...i dont think i had the catless mid pipe on yet i cant remember though
but now my set up is a 4-1 header stock midpipe and megan cbe
sounds exactly the same as stock header with catless midpipe
had it with the testpipe and the header for like a day, sounded horrible, but the power gains were pretty noticable
