I have so many great things to say about Perrin and their customer service. This was my first Perrin product and I was blown away by the quality of the exhaust when I received it in the mail. The exhaust is made of stainless steel and all of the welds were absolutely flawless. The sound is just what I was looking for. The low growl that this exhaust produces really showcases the fa20's boxer rumble. The install was a breeze and I could not be happier. When I installed this on my car it was my first mod and the rest was completely stock. I noticed a lot more response from the throttle and it picked up a little bit faster than before, a real noticeable improvement. I installed this along with the Perrin 3' front pipe which they no longer produce. The guys over at Perrin Performance really know what they're doing.
