perrin 3in resonated and non resonated vs the greddy evolution gt
 

I'm currently trying to decide on a exhaust for my brz. I'm going to be going turbo this year so I'd prefer a 3in exhaust. Everything will be stock besides the catback until I go turbo. I want something that is louder than stock. Something you can definitely hear but isn't obnoxious. Deep tone with minimal rasp and drone. Perrin non resonated, resonated, or the new greddy evolution gt?

Based off my personal recommendation between the 2 PERRIN options, I would go with the resonated option we have.

I've personally had the non-resonated option on my BRZ and I did love the sound. I felt as if it was the perfect mix of loudness and deepness for the exhaust tone. However, I also had no plans to switch out the header/front pipe which would have made that exhaust too loud for me.

I feel as if the resonated option we offer is the most "mature" option that we have. It has an awesome sound and I think mated up with a header/front pipe, it would sound even better.
