"Resonators
Resonators are smaller diameter mufflers. They lack the volume of larger mufflers but fit in places where a full size muffler will not. Use them to help quiet down a loud system. Different lengths will affect different sound frequencies. These will help reduce droning on systems with just a single medium muffler at the rear.

Perforated core resonators do not affect flow at all. Louvered core resonators will flow about 5% less but do a better job at silencing things."

Which do you guys think I should go with ? I installed a open track pipe/ free flowing exhaust system i have 2.5 inch piping. I think If I go with the Louvered core I might get more aggressive sound which Is what I want. Im not a 100 % so I wanted to know has anyone done this yet ?

 

What is the outcome you want to achieve? Better sound or better performance?

 

With my current setup I have the raspiness, I want to get rid of that so with the two options described above thats what i am going to choose today. I do want better performance, I guess better performance would be the louvered core and the better sound would be the perforated core am I right ?

 

That's exactly why.... You have to decide if you're interests are more towards better performance or better sound.... It's all a matter of personal preference when it comes to these things....

 

Damn man this is nuts cuz when I was there yesterday I only saw the louvered core pipes not the preforated core pipes. That might mean something lol maybe its destiny for me to get the louvered which ever I choose today should clear that raspiness ill def post a sound clip

 

Cool....

 

I need a TSX buddy would you like to be the first ? I love my car man but I dont talk to any of my bro's about it because not only do they not know anything about cars its not their hobby.

 

Did this project also this weekend. Came out great ! My exhaust sounds pretty good. I am still getting the magnaflow mufflers and it will sound even better. I also changed my spark plugs NGK Laser Iridium of course for the win !!!!. Car performs a bit better. You notice it as well. Next project getting my kyb struts done for the rear this friday.
