Cobb exhaust primary resonator question
 
I have an aftermarket 3"exhaust and with equal length exhaust manifold and it's super Honda now. I'm going to add a resonator and the cobb one looks like the biggest we can fit.

Anyone have this exhaust that would be willing to get a rough measurement of its overall diameter and length?

Much appreciated guys

Or just whatever monster someone has managed to fit where the stock resonator goes would help

Vibrant 3" resonator, pretty beefy, good reviews all around. $80 on Amazon, I think its something like 15 inches long.

Alternatively you could get a glasspack that's longer and weld it into the mid pipe. I'm pretty sure that would fit just like the stock resonator, but it's just longer.

The Vibrant was one first choice but I looked into it more and wanted to try and get something larger there, like:


I don't think it will fit based on the diameter. Might still go vibrant and see how I like it

Looks beefy but also consider the vibrant being beefy width wise which I think would help out more. Plus many members here seem to love it for killing unwanted sound, which is why I was suggesting it. Lot of people seem to have good results with it.

For what it's worth, my friend killed some raspyness on his gen with a long glass pack welded in. Worked out well and it's lower profile than the vibrant.

Thanks for the help man, I think the vibrant will the route I go then.

Probably won't get around to actually getting it welded in for a while but I'll do a before/after
