well I'm having mixed reactions about redoing my exhaust. i currently have stock headers, with an off road x pipe, and 40 series flows. but i have my mind made up on getting slp lm1's, because i love that sound and i want to go louder 
but a friend of mine told me that i will have backpressure issues with the lm1's and that i will actually lose power and that the end result the car wouldn't sound that good anyways. whats the real truth behind this? will i have probelms and end up losing power? thanks guys
