I just installed the invidia q300 true dual last week and am impressed with the quality and the sound. however i am a little disappointed with the sound level being similar to stock. The question is.... What should give me a little sound boost without sacrifices the sound quality. In a few words I don't want any rasp buy want a deeper richer louder sound. Test pipes? Which one recommended? or High flowing cats? which ones recommended?

Thanks a ton

 

fast intentions high flow cats.

 

are those the loudest or just best bag for the buck? i just want the best quality and louder

 

Berks HFC are great quality and cheaper than the others.

 

i just realized that there are resenated test pipes as well. do those have a rasp at all? how do these compare?

 

Go with the Berk HFC's. I just installed them on my car. I have the Q300 as well. Best combo. No rasp. slight drone when cruising but you will enjoy it. Trust me!!! Getting lots of compliments.
