So I had the muffler shop remove all heat shields to see if there was a rattle and still the same sounds not even the slightest improvement... So it's deff rasp

so I know adding resonators would help but the whole reason I wanted to remove them was bc the nismo was to quite even with the berks HFC... So back to square one..

I have someone who wants to buy nismo axleback for $150 so atleast I can get some money back..

Thinking about trying the topspeed axleback first and adding resonators to help with rasp.. I assume adding the resonators to the topspeed will still be louder then the nismo.. From what I see on YouTube I like the sound.. Short tails are to loud I think..

What I really really want is some type of axleback that has resonators already on them just can't find any..

So final ? Do you adding 2 - 12 inch resonators to the topspeed axleback will limit the rasp and still have the same loudness tone as the non resonated nismo ?
