Thanks. Just for imagination, these two setups I found are probably the best so far:

http://www.apexi-usa.com/store/index...cion-fr-s.html As for why it's frustrating, it shouldn't come as any surprise. You're trying to reverse engineer what OEM engineers spent months doing: tune out unwanted noises and meet power/emissions/economy guidelines as set forth by project goals and regulations. I suggested Apex'i purely because it now gives you the option of running whatever exhaust you wanted to achieve the sound you seek, without sacrificing performance (i.e. with stock front pipe). -alex |

I personally want my car to be as quiet as possible after owning a catback with drone.
My current setup is Tomei EL Custom T1r catted front pipe (100cell) Stock everything. Stock catback does have abit rasp with this setup. Right now it is really quiet during idle and it roars when u put ur foot to the floor. I might look into getting an axleback in the future. example of sound: [ame="https://www.youtube.com/watch?v=vZQaZU5e_Ts"]UBCSCC Autox - 2016/09/25 - Personal Best - YouTube[/ame] |

Thanks! It seems it sounds good. @mav1178 Thanks. That apexi setup has one 130cel cat. I don't believe that that doesn't smell, when people reporting smell even with 200 cels. And is that dyno tuned? Because the gains are about half of what other ELs can do. |

Question for you which would sway my answer.....are you going to run FlexFuel/E85 or strictly pump gas? If you're going to be sticking with a Naturally Aspirated setup on pump then going with a catted header will be a huge compromise as that is pretty much almost all of you what you stand to gain. But, if you will be tuned for ethanol then that will get you to third base so to speak as far as N/A performance gains. This is what I suggest;
Header: See comments above. Do not opt for catted, leave the factory exhaust in further downstream if noise level is that important to you. This will save you a pretty penny in the process. Tomei headers are loud due to thin pipe walls. Front Pipe: Stock or anything with a cat in them. From what I've seen they're all similar in tone. Berk frontpipes, even HFC, seem to be loud as the walls of the pipes are pretty thin. Catback: Blitz Nur Spec C-TI Invida Q300 Perrin Resonated Milltek Greddy Supreme SP HKS Legamax Stock and just get some tips |

Not entirely true, a well designed header with a high flow cat has a pretty small impact on overall flow and helps dampen rasp.

You can believe what you want about smell and what others have reported. The facts are this:
There's a lot of questions you want to find out, I would suggest you start with Apex'i first. All I can tell you is that the car that has the Apex'i header setup is sitting about 100m away from me right now, and it doesn't smell during normal driving. Quote:
Having said that... Having (or not having a catalytic converter) in your front pipe is not what determines the sound of the entire system. It's the resonator(s) and whether the volume of the resonators work well with the rest of the exhaust to suppress sound at certain frequencies. I drove an entirely catless setup (Tomei UEL, Tomei OP, Fujitsubo FP, Blitz VSR catback) from LA to Austin, ran at COTA, and drove back to LA. It had no drone, it sounded great under WOT, it sometimes smelled, and it was otherwise uneventful. -alex |

@Amputechture as @bfrank1972 said, it is not just about the cat. Also it is true that I am not interested in E85, we have RON101 here so I will stick with that.
@mav1178 ok thanks for your input. I just red, that @P&L Motorsports has thicker walls than others. That might be cool, because they have EL catted too. |
