I drive 2006 is350. I just ordered ppe headers and soon I will order exhuast. I like the borla exhuast sound. However, another option is invidia midpipe with borla exhuast (muffler). Which is another idea.

I cannot find any videos online of the sound of ppe headers+invidia midpipe+borla. The reason Im considering invidia midpipe is because its so famous.

So: ppe headers+borla full exhaust

or

ppe headers+invidia midpipe+borla end?
