Custom Straight Pipe Resonator sizing question?
So I've been planning on getting a custom exhaust for my KA (which is currently NA, will be tuning and setting up for Turbo this winter possibly)
I have been thinking of going with an 3" pipe all the way to 4" tips (pretty much similar to ISIS 3 to 4" exhaust) Now I'm definitely plan on adding a resonator, but I'm not exactly what size should go with, but pretty much I have added two choices. The Vibrant Performance Bottle Style 12 inch resonator or 18 resonator. Now I haven't measured the midpipe (which I should have, but I have not be able to) and I was possibly thinking maybe the 18 would be pretty long. Also in terms of reducing rasp, which one would be better? I assume the 18, but is there really a distinguishable difference between the two lengths? I already know it's going to be loud, I run N1 Duals currently, so not pressed about loudness, but I'm worried about potentially excessive raspiness from the NA KA currently and trying to get a smoother, deeper and loud tone. I specifically would like get input from guys who is running a similar system on a NA KA, cause once I go turbo I know it will reduce the raspiness greatly, but I don't plan on installing that just of yet, so it will be on a NA KA for now. Thanks for the input.

I don't think an 18" resonator will sound drastically different from a 12" one. It's been said the longer the resonator, the less raspy the note. I would contact Vibrant if I were you and speak to a representative though as they will know best.
But personally I wouldn't worry about tuning your exhaust note just yet. Turbo KA will always throw problems at you, save your money for the problems that will without a doubt show up. |

and yes you are right man about the issues, I seen that you have been going through constant ECU changes, because your KA keeps running lean. Have you got any idea what's up with that? The car came with N1 Duals when I bought it so I don't have a stock exhaust and winter is coming and they salt the living hell out of these roads here. I pulled my exhaust because I'm replacing my trans and come to find out, it's a legit Apexi N1 Dual exhaust and with that said, I rather have something cheaper than the Apexi, IF I happen to be presented with a event that I have to drive my car this winter. Hopefully not.
