decibels are a measure of loudness not tone

if your car was only making 6 dB of noise, you would not be able to hear it


I suspect you mean 6 and 8 bels, (60, 80 dB)

8 bels is 4 times louder than 6, not 9% (it's a logarithmic scale, like the richter scale)

I think you would get more droning without the resonators..ie cruising speed.

At the end, it's up to you. I can't decide for you because I don't know how loud your car is.

My last car was an Evo with a full turboback...for sure the exhaust I had was illegal, you can hear me coming from a mile away, the interior was constantly drowning at all RPM...everytime you drive there would be loud sound with deep vibration. It gets old after a while. You may want to get some giggles out of setting off car alarms for the first few days, but it gets to you sooner or later.

This was my exhaust before I even got my hi flow cat and downpipe...I thought it was cool at first to 'unleash' the beast with the sound. But I honestly got tired after a while.

i've heard a fellow member's car with an ikon and a deleted resonator. It definitely drones at lower RPM. Personally it's a little too loud for my taste. When i had my ikon installed, i decided to not delete the resonator and i'm glad i didn't. It's perfect inside the cabin, while people who've heard it outside say it's has a nice throatier tone, but not over obnoxious.

BTW - give it some time, your exhaust will get a little louder once the muffler has broken in. If you still want to delete the resonator, wait until you've put a few hundred miles on the car first.
