Help Kooks Headers vs Corsa CB Exhaust

[blkout]

If anyone has ARH headers, would love the feedback. It was Kooks only for so long, but we finally have choices.

ARH are fantastic, they have always been top quality.

I have a thread here about my exhaust mods. I replaced factory mufflers with aftermarket pass-through mufflers. Re-used factory tips. Local shop custom made all the mods for under $750. It sounds much better, but still not enough for me.

Its noticeably louder than stock with the flaps open. But still quiet enough that you don't notice it while maintaining conversation with your passenger. The flaps still quiet it down if necessary, but I never find it to be so.

Unfortunately, the shop nor I knew about the procedure to re-link the ECU with the muffler flaps, so I did get a CEL even though I changed nothing related to cats or upstream from the mufflers.

I don't understand why y'all are even considering keeping stock mufflers with headers though. It defeats the whole point of headers to keep stock mufflers.

My warranty is up next Spring, so I plan to add the Kooks and get it tuned anyway. I figure the flaps will keep it contained enough if I ever need to. The tune is ridiculously expensive, but there are few conveniences I just want to have....and killing the CEL will be nice. Ironically, the CEL is hidden behind my steering wheel, so I forget about it.

Can't wait to fire it up after that

Not sure I understand regarding the CB exhaust. Many factory exhausts are made really well and sound great. Changing the CB exhaust often adds minimal power gains and often little exhaust note differences. IE my other car is an F12. If you swap out the exhaust it does next to nothing and it will cost you $10k. Swap the 800 cel cats for race/green cats, with the factory exhaust, and it’s a completely different ballgame. It fucking screams. Best upgrade by far.

In all honesty from the videos I have seen I really don’t hear that much of a difference going from factory exhaust to Corsa Extreme but that might just be the videos. That is why I was thinking about going the same route as my F12 (green cats and factory CB). If anyone lives around the Westchester, NY area and has a Corsa installed I would love to meet-up for a listen.
