I recently came into a ceramic coated cobb downpipe, which I installed with my stock catback on my hatch. Now my buddy just came into a cobb downpipe that the cat has been gutted out of, and wants to trade with me just so his can be a little quieter. I eventually hope to get the GReddy SP Elite catback when I can afford it, and wanted the Nameless Performance downpipe because I like their design, but I don't have the money.
So anyways just wanted opinions on catted vs catless basically, I know it's been asked a million times but figured I'd throw it in here with specifics regarding the same downpipe and how it might have an effect on noise and power. Thanks.

Stock catted dp vs aftermarket dp? That's what I'm seeing in that video.
That's not an accurate comparison unless that's what he was asking. I thought he was asking aftermarket catted dp vs non catted aftermarket dp |

Aftermarket catted vs. aftermarket catless downpipe is barely any change in sound.
You can get boost creep with either, but it's more likely with catless (which basically proves how much better flow you're getting). |

I respectfully disagree..sort of. To clarify, I noticed differences between a non-resonated midpipes and CBE, in respect to exhaust volume. The resonated midpipes really (as you said) there isn't much of a difference Last edited by Louie; 08-17-2012 at 08:20 PM. |

Do NOT use his results as a basis for your decisions. He has a sedan. You have a hatch. Completely different. This is how misinformation starts. The hatch stock exhaust is the quietest you're going to find.

Listen to him ^ as he knows his stuff!
However, keep in mind that it's not always the "loudness" of the exhaust that bothers people. Excessive vibration or drone bothers most people more than the actual volume. While I've never heard a stock hatch exhaust I can imagine if the low RPM drone is anything like the stock sedan exhaust, it gets annoying fast. That's why I have no problem upgrading to a slightly louder setup overall because I've now heard it in person and I know it sounds better in the cabin than the stock and SPT exhaust. And those two exhausts are "supposed to be" the quietest exhausts you can get on a sedan, again touching on my point about loudness (volume) versus vibration/reverberation (drone). |

ok exhaust rattle fixed!!!
kartboy exhaust hangers did not work, great product, but it brought the exhaust even colser to the frame, because they are very stiff! kartboy XL exhaust hangers also did not work, well it did work, solved the rattle problem but put the exhaut too low and i would scrape everywhere, hahaha solution was hammer the **** out of the heat shield above the midpipe, and grind down one bolt from the v-band clamp so it wouldnt scrape! |
