But, indeed the PPE header would lower sound level and make most of the gains that you get with full open header (giving up just a little at top of RPMS).
Thanks Brian for your fast reply.
I love the JDM look of the GReddy so i will definitely keep it.
I've seen in your site the PPE header and the Beat Racing midpipe with the presilencer.
My thought of adding the Racing Beat midpipe with the presilencer after PPE's catalyst is right? Because the stock midpipe has a catalyst too, and the PPE comes with a 200 cells catalyst.
So, the combo PPE header and RB midpipe with silencer is sound level acceptable?
