I have them on all my cars - minimal maintenance and better performance/fuel economy

The american thunder exaust system for the V6 Bird a is nice upgrade from the stock system. It gives it a nice deeper sounding tone but it is still a far cry from the V8 version. I just thought that it would come a little closer to it's big brother. But that's a good as you are going to get in a V6.

I had the high flow lid type set up with K&N filter. so I didn't think I would see much more improvement. I was wrong I definitely noticed a difference in throttle response and torque. I had put off buying because I think it's a little pricey but I needed to maximize my air intake and all intakes out there are a little pricey anyway so I went with what I've used in the past and had good results. witch was K&N very happy with the results.
