I was talking about the axel back to remain compliant. Header and factory exhaust is a good power low noise solution

I have sikky headers and stock exhaust and the sound is pretty quiet and no drone at all!!

on that note I'm gonna be buying the Borla exhaust to extract the full potential of the engine, hopefully I can deal with the extra noise...

but headers and stock exhaust is definitely the way to go if you wanna stay quiet!

My friend has Borla exhaust and it was rather quiet. I got Sikky header and Borla exhaust and its been pretty pleasant in the cabin.

I would build my own dual system…. maybe look at using some parts from the dual system on the LS 460. The RC F now uses a dual system that looks like the 460 system.

Lol, getting wife approval on stuff like this is like finding the holy grail and is the ultimate stamp of approval! She will forget all about the noise when you get on that skinny pedal and she feels all those ponies the Sikky headers are uncorking!!!

^^ The OEM RC F exhaust system is NOT anything great to modify...
(same for LS460)

It has several size variations and TWO major flat spots on the rear axle pieces..

I've looked at the RCF exhaust system, and Mr. Z is exactly right.

I love how the video is titled 'Dynojet Results" and then doesn't show any results

I would not use the obviously restrictive pieces. However, the crossover H pipe and and first set of resonators, if not too small, could prove beneficial in constructing something.
