The HKS is one of the best sounding exhausts for our car. It is a 60mm (same as stock) but I havent seen someone bolt one on and dyno right after in the same conditions on the same dyno and lose any power. The HKS one is quiet too, almost like the Invidia q300 which you say it to quiet. So I say if you want power, dont get it. If you want it for sound, hell yeah! Yeah just get that header and test pipe like you said, and get either the Greddy Ti-C or get the HKS 75mm Single.

 

so you don't think the skunk2 is a good choice? I think its pretty good for the gains and weight loss.
